Abstract Abstract
Herminium (Orchidaceae, Orchidoideae) is a medium-sized genus widespread in the northern hemisphere, with a clear centre of diversity in the Himalayas. We present a comprehensive taxonomic revision of Herminium based on field observations and morphological studies, for which we examined about 2500 specimens. We recognize 49 species grouped into six formal sections, including one new species, Herminium tibeticum, from Tibet. We provide an identification key to the species, descriptions of the species, notes on ecology and distribution, and complete nomenclature for each species, including typifications. We here designate lectotypes for five species and reduce four taxa to synonymy.

Introduction
Herminium L. is a widely distributed genus, ranging from Europe through most of continental Asia to Japan, the Malay Archipelago and New Guinea (Fig. 1). However, most species are restricted to continental Asia, in particular to the Pan-Himalayan region, with only one, non-endemic species each in Europe (H. monorchis) and tropical Southeast Asia, including New Guinea (H. lanceum) (Hooker 1890; Tang and Wang 1937, 1940; Lang 1988; King and Pantling 1898; Press et al. 2000; Pridgeon et al. 2001; Pearce and Cribb 2002; Chen et al. 2009; Averyanov and Averyanova 2003; Averyanov 2010; Kurzweil 2010; Lee et al. 2013; Kurzweil and Lwin 2014).

Geographical distribution of Herminium.
In most of the earlier, floristic literature, such as Duthie (1906), Hooker (1890), King and Pantling (1898), and Tang and Wang (1937, 1940), Herminium was accepted in a broad sense. More recent authors, such as Seidenfaden (1977), Hara et al. (1978), Hunt (1970), Lang (1988), Pridgeon et al. (2001), Agrawala et al. (2010) and Ormerod (2013) took a more narrow view to the genus and recognized a number of small satellite genera, including Androcorys Schltr., Bhutanthera J. Renz, Frigidorchis Z.J. Liu & S.C. Chen, and Porolabium T. Tang & F.T. Wang. Raskoti et al. (2016) found that these satellite genera as well as certain misplaced members of Peristylus Blume and Platanthera Rich. were nested within Herminium s.l. This led these authors to propose a broader delimitation of the genus, which we also adopt in this revision.
As redefined, Herminium is a genus of 49 species of predominantly terrestrial orchids in the subtribe Orchidinae, characterized by having a (sub)globose tuber, a lip with a concave or spurred base, and pollinia with reduced caudicles. Unlike in the closely related genus Peristylus, the stigma-lobes are not adnate to the base of the lip. Most species have quite small, greenish, whitish or yellowish flowers arranged in racemes. Apart from regional treatments (e.g. Chen et al. 2009, Pearce and Cribb 2002, Pradhan 1976), no modern revision of the genus as a whole has been undertaken before. Here we present such a revision, which should make it easier to identify these inconspicuous orchids.
Materials and methods
Vegetative as well as reproductive characters of Herminium were examined in the natural habitats and in herbaria. Herbarium specimens collected during our fieldwork were deposited in the Chinese National Herbarium (PE) and the National Herbarium and Plant Laboratories in Nepal (KATH). Flowers were preserved in formalin-acetic-acid-alcohol (FAA) for further study. Such material was studied in the laboratory under a stereomicroscope. Photographs and measurements were taken using image software of Nikon Instruments Inc., NIS-Elements D 3.10.
Specimens deposited at CAL, CDBI, DD, E, HNWP, KATH, K, KUN, LINN, PE, SIN, TI, and TAIF herbaria were examined. Photographs of the specimens were also studied from several herbaria (such as NY, P, UPS, W) where direct access was not possible. Over 2500 specimens, including types of most species, from the distributional range of Herminium have been examined.
Vegetative characters, such as tuber, leaf shape, phyllotaxy, and peduncle scales, and reproductive characters such as sepals, petals, lip and column, were examined. Flowers of dried specimens were rehydrated in boiling water prior to dissection. Floral characters such as bracts, sepals, petals, lip, and column were observed and measured with the help of a stereomicroscope. Literature, including Hooker (1890), King and Pantling (1898), Tang and Wang (1937, 1940), Pradhan (1976), Lang (1988), Press et al. (2000), Pearce and Cribb (2000; 2001), Boufford (2003), Chen et al. (2009), Agrawala et al. (2010), Averyanov (2010), Raskoti (2012, 2013), Ormerod (2013), Kurzweil (2010), and Kurzweil and Lwin (2014), was consulted for general distribution data and to assess some morphological characters of species we have been unable to examine ourselves. Thirty-seven morphological characters were compared (see Raskoti et al. 2016), and a set of diagnostic characters was chosen for the preparation of a dichotomous key. Based on phylogenetic analyses (Raskoti et al. 2016) and comparison of morphological characters with its relatives, a new species (Herminium tibeticum) is described and illustrated (see taxonomic treatment).
Habitat information is based on field observations, literature and herbarium labels. The distribution map was produced using DIVA GIS 7.5 (www.diva-gis.org) based on labels of representative specimens as well as data in the literature (e.g., Pearce and Cribb 2002, and Chen et al. 2009). Phenology is based on field observations of authors, information of lables and data in the literature (e.g., Pearce and Cribb 2002, and Chen et al. 2009)
General morphology
Tuber: Unbranched, smooth, globose to oblong or ovoid. Slender roots are produced from the stem just above the tuber. The simple, rounded tuber in Herminium represents a major difference with the subterranean parts of Eurasian species of Platanthera, in which a tuber is either absent or is drawn out into a tapering, root-like tip (Fig. 4).
Figure 4.

Phyllotaxy: Leaf number and arrangement vary in Herminium. Leaves can be single or paired, or there can be more than two leaves; they can be basal or cauline, opposite, subopposite or spirally arranged. Except for H. monophyllum and H. monorchis, most of the subtropical and temperate species have several cauline leaves (e.g. Herminium lanceum, Herminium longilobatum, Herminium clavigerum) whereas subalpine and alpine species have only one or two basal leaves.
Leaves: Leaf shape in Herminium varies from linear, oblong, lanceolate, ovate, ovate-orbicular to sphathulate; the basal part always forms an amplexicaul sheath; the leaf apex can be obtuse, acute or acuminate. Linear leaves are restricted to subtropical and temperate species (H. lanceum, H. longilobatum, H. mackinnonii, H. quinquelobum); however; some subtropical and temperate species have ovate to oblong leaves (H. latilabre, H. clavigerum). Leaves may be shortly petiolate (H. humidicola), but are usually sessile.
Stem: Erect, glabrous. The stem may be abbreviated as in H. humidicola, H. handelii, and H. albomarginatum or elongate as in H. clavigerum, H. edgeworthii, and H. lanceum. The stem is covered by tubular sheaths but these do not produce a pseudostem, except in H. humidicola.
Inflorescence: This is almost always an unbranched raceme but in H. humidicola it is subcorymbose. The peduncle is cylindrical and smooth, except for the winged peduncle in H. hongdeyuanii. Most species have an elongate, densely many-flowered rachis (e.g. H. clavigerum, H. longilobatum, H. lanceum), but some, such as H. humidicola and H. albomarginatum have a short rachis with few, sometimes laxly arranged flowers. The peduncle may be shorter than the rachis or sometimes much longer.
Peduncle scales: In the subtropical and temperate species of Herminium, foliaceous peduncle scales are present (e.g. H. lanceum, H. latilabre, H. edgeworthii, H. fallax) but in several subalpine and alpine species, such as H. pugioniforme, H. josephi, and H. fimbriatum, they are absent.
Floral bracts: Most species have floral bracts, except Herminium humidicola, in which they are lacking. The shape of the floral bracts shows some variation. They can be ovate or triangular as in H. albomarginatum, H. oxysepalum, and H. chloranthum; reduced to tiny scales as in H. pugioniforme and H. biporosum; or they can be lanceolate as in H. monorchis, H. lanceum, and H. fallax. Floral bracts may be (sub) equal to the ovary as in H. josephi, H. himalayanum or distinctly shorter, or longer, as in H. clavigerum.
Ovary: Like all orchids, Herminium has an inferior ovary, which may be sessile or pedicelate, straight to arcuate, or twisted as in H. biporosum. Its shape ranges from cylindrical to fusiform. The ovary is usually beaked (abruptly tapered) at the apex. In Herminium monorchis and closely related species (H. ophioglossoides, H. pygmaeum) the ovaries are beaked and decurved.
Flower: Most species of Herminium have inflorescence with spirally arranged flowers, but several have subsecund flowers, e.g. H. monophyllum (Fig. 5). The flowers are resupinate (rarely not resupinate), small, usually pale to yellowish green as in Herminium monorchis, H. chloranthum, but sometimes white (H. coeloceras, forms of H. macrophyllum), whitish-green (e.g. H. mackinnonii, H. jaffreyanum), or rarely more colorful, as in the white-and-red H. albosanguineum. In some species the flowers open only slightly (e.g. H. humidicola).

Dorsal sepal: Always concave. It can be ovate (e.g. H. josephi, H. souliei, H. alaschanicum, H. macrophyllum), elliptic to ovate-oblong (e.g. H. fallax, H. latilabre, H. monorchis, H. quinquelobum), or lanceolate-oblong (H. quinquelobum, H. ophioglossoides, H. glossophyllum) (Fig. 6). Some alpine species (e.g. H. humidicola and H. biporosum) have a nearly orbicular dorsal sepal. The dorsal sepal may be spreading, as in H. monophyllum and H. mackinnonii, or connivent with the lateral sepals or petals forming a hood, as in H. biporosum, H. lanceum, H. chloranthum, H. elisabethae, H. fallax, and H. alaschanicum.

Lateral sepals: The shape of lateral sepals is rather variable: oblong-obovate (H. monorchis), ovate-oblong (H. lanceum), ovate-lanceolate (H. fallax and H. alaschanicum), oblong-lanceolate (H. macrophyllum), ovate (H. latilabre and H. elisabethae), ovate to elliptic (H. pugioniforme), obliquely elliptic (H. chloranthum), or elliptic-oblong to elliptic-lanceolate (H. clavigerum) (Fig. 7). In most species, lateral sepals are spreading but they are completely reflexed in H. clavigerum, H. latilabre, H. edgeworthii, and H. pugioniforme; in H. gracile they are reflexed so as to become parallel to the lip. In H. latilabre, H. edgeworthii, and H. clavigerum, the lateral sepals have ciliate margins, whereas these are denticulate in H. oxysepalum.

Petals: Connivent with the dorsal sepals, except in H. jaffreyanum, H. monophyllum, H. quinquelobum and some other species, which have free, spreading petals. Their shape varies considerably: linear (H. fallax, H. lanceum, H. souliei, H. quinquelobum, H. mackinnonii, H. jaffreyanum, H. monophyllum), lanceolate (H. chloranthum, H. pygmaeum), oblong-lanceolate (H. ophioglossoides), ovate-lanceolate (H. macrophyllum, H. josephi, H. elisabethae), ovate to broadly ovate (H. biporosum, H. coeloceras, H. macrophyllum, H. ecalcaratum), oblong (H. coiloglossum), rhombic (H. monorchis), or spathulate (H. himalayanum) (Fig. 8).

Lip: Usually 3-lobed and with a concave and ecallose basal part that may be dilated as in H. coiloglossum, H. lanceum or not dilated as in H. alaschanicum. Some species, such as H. coeloceras, have a callus on the lip. In a few species the lip is entire, as in H. monophyllum, or 5-partite, as in Herminium quinquelobum. The shape of the lip may be ovate (H. josephi), oblong (H. lanceum), lingulate (e.g. H. biporosum, H. latilabre), or ovate-lanceolate (e.g. H. macrophyllum) (Fig. 9).

Spur: Lacking in most of the species, but a significant minority have a spurred lip (H. alaschanicum, H. albomarginatum, H. albosanguineum, H. albovirens, H. bulleyi, H. clavigerum, H. edgeworthii, H. quinquelobum, H. fallax, H. fimbriatum, H. forceps, H. handelii, H. himalayanum, H. humidicola, H. latilabre, H. mannii, H. singulum, and H. suave). The spur may be cylindrical (e.g. H. edgeworthii) or scrotiform (H. alaschanicum, H. quinquelobum, H. fallax). It is usually shorter than the ovary (e.g. H. alaschanicum, H. quinquelobum, H. forceps) but in a few species the spur is longer than the ovary (e.g. H. latilabre, H. edgeworthii) (Fig. 5). In some species, such as H. josephi, H. monorchis, H. ophioglossoides, and H. pygmaeum, the lip has a saccate base, which can be almost like a spur.
Column: Short but well-developed (Fig. 10). The anther is adnate to the column apex, 2-locular, with the locules parallel or divergent. Pollinia 2, oblong to ellipsoid, granular-farinaceous and sectile, with very short or vestigial caudicles. Viscidia globose (H. lanceum, H. longilobatum) or often involute, naked and hornlike (H. alaschanicum, H. josephi, H. monorchis) (Fig. 11). Rostellum triangular, often with arms. Stigma lobes 2, free, sometimes confluent, usually clavate and raised, in some species, such as H. albomarginatum and H. pugioniforme, pulvinate; in H. latilabre and closely related species the stigma lobes are extended along the entrance of the spur, but not adnate to the lip base as in Peristylus. There are two, usually prominent auricles laterally at the base of the anther.

Fruits: A capsule; longitudinally dehiscent; usually erect, beaked, oblong or fusiform, in some species it may be twisted.
Ecology
Almost all species of Herminium are terrestrial, but a few, such as H. lanceum (Thunb. ex Sw.) Vuijk, H. mackinnonii Duthie and H. quinquelobum King & Pantl., occasionally grow as epiphytes on tree trunks or major branches of large trees (Fig. 2). Forests, woodlands and grasslands are a common habitat of Herminium, where the species grow in humus-rich soil in light shade. Many species are subalpine or alpine, growing fully exposed in high mountain valleys and meadows (e.g. H. albomarginatum, H. josephi, H. monorchis, H. pugioniforme) or on peaty soil in moraine areas (e.g. H. alaschanicum, H. chloranthum).
Figure 2.

Herminium pugioniforme appears to reach the highest elevation of any orchid, said to occur up to 5500 m (Pridgeon et al. 2001; but see note under H. pugioniforme below). In contrast, H. monorchis grows at sea level in part of its range, e.g. in The Netherlands. In tropical and subtropical regions, all Herminium species are mountain plants, with many species growing at an elevation of around 4000 m (Fig. 3). A few species, such as H. lanceum, H. souliei and H. monorchis, have a wide distributional range, but many more, about one quarter of the species, are narrow endemics, including H. albosanguineum, H. handelii, H. kamengense, H. oxysepalum, and H. pygmaeum.
Figure 3.
Elevational range of Herminium.
Little, if anything, is known about the pollination of nearly all species of Herminium. Only that of H. monorchis has been thoroughly studied (Nilsson 1979; Claessens and Kleynen 2016). The honey-scented flowers of this taxon produce small quantities of nectar and attract various species of minute insect, in particular parasitic wasps, flies, mosquitos and even beetles (Claessens and Kleynen 2016). The most important pollinators in Sweden were found to be female parasitic wasps of the genus Tetrastichus (Nilsson, 1979), which accounted for 65% of pollinia transfers, with other parasitic wasps accounting for 12.2%, while Diptera only accounted for 7.8%. Most Herminium species are superficially similar to H. monorchis, in that they have small greenish flowers, and they may have similar pollinators. A few species with longer spurs and larger, Platanthera-like flowers (here included in the new section Pseudoplatanthera), may well be moth-pollinated.
Phenology
In the Pan-Himalayan region, vegetative growth of Herminium species starts in March–May and flower buds appear in June. Flowering begins in June and reaches its peak in August. Fruiting occurs largely simultaneously with the flowering time. Leaf and stem decay in November–December. In the middle of winter, i.e. during December to February, plants of Herminium are dormant, surviving as subterranean tubers.

Note.
When describing Herminium gracile, King & Pantling erroneously interpreted the base of the lip with its two concavities as being part of the column, hence they and later authors believed that this species lacked the basal concavities of the lip that are seen in H. pugioniforme. In fact, the two taxa are quite similar in lip morphology, but differ in that H. gracile has well-developed caudicles (rudimentary in H. pugioniforme), distinct, elongated anther-channels (rudimentary anther channels), and deflexed lateral sepals that are held parallel with the lip (patent lateral sepals). In addition, H. gracile usually has a much more slender inflorescence with more widely spaced flowers. We find no significant differences in the protologue of Androcorys ophioglossoides; the fact that Schlechter stressed the uniqueness of this species makes us suspect that he did not compare it with Herminium gracile.

Excluded species
Herminium gongganum Ormerod, Taiwania 58: 27 (2013).
Note. Judging from the protologue, an image of the holotype, and our own field observations of similar plants (which had fleshy rootstocks, lacking a tuber), this taxon belongs to the genus Platanthera. Efimov (2016) transferred this species to Platanthera.
Herminium orbiculare Hook.f., Fl. Brit. India 6: 129 (1890).
Note. Based on an examination of living and type material as well as a phylogenetic analysis using DNA data (Jin et al., unpublished) it is apparent that this species belongs in Platanthera, necessitating the following new combination.
