Abstract
Two new species from Borneo that have been described in the genus Callerya are shown here to belong in Adinobotrys. The new combinations A. katinganensis and A. sarawakensis have consequently been made, bringing the total number of species in the genus to four. A morphological key and taxonomic conspectus is provided for all species.

Introduction
Schot (1994: 15) included Pongamia atropurpurea Wall., in her revision of the genus Callerya Endl. (Endlicher 1843) as Callerya atropurpurea (Wall.) Schot., the species having already been segregated from Millettia (Wight & Walker-Arnott 1834) and Padbruggea Miq. (Miquel 1855) into the genus Adinobotrys Dunn, on the basis of apparently having a stipitate ovary and one-seeded pods (Dunn 1911: 194). Schot regarded Adinobotrys to be synonymous with Padbruggea Miq. The distinction between Adinobotrys and the genera Padbruggea and Whitfordiodendron Elmer, 1910 was fully discussed in Compton et al. (2019: 35). Adinobotrys was typified on the species A. atropurpureus (Wall.) Dunn by Geesink (1984: 83) based on Pongamia atropurpurea Wall. (Wallich 1830).
Research based on morphology, NrDNA and CpDNA sequence data has led to the redefinition of the Callerya Group of genera within the Inverted Repeat-lacking clade (IRLC) of legumes as an enlarged Tribe Wisterieae Zhu (Zhu 1994) comprising 36 species within 13 genera (Compton et al. 2019). The same research revealed that the genus Adinobotrys (Dunn 1911) was sister to Glycyrrhiza L., (Linnaeus 1753) and Tribe Wistereae and that another tree species Callerya vasta (Kosterm.) Schot, also belonged in Adinobotrys (Compton et al. 2019: 20).
Adinobotrys as circumscribed by Compton et al. (2019) comprised two species; A. atropurpureus (Wall.) Dunn and A. vastus (Kosterm.) J.Compton & Schrire. Adema (2019) has subsequently described two new tree species in Calleryasens.lat. (Schot 1994) from Borneo, which are placed here in Adinobotrys, bringing the total to four species.
Several morphological characters separate Adinobotrys from Calleryasens.str. (Compton et al. 2019: 35): Adinobotrys comprises species of evergreen trees (vs. lianes in all genera of Tribe Wisterieae); its bracteoles are persistent, placed on the calyx (vs. mostly caducous and placed on the pedicel in Calleryasens.str.); its standards are glabrous (vs. sericeous in Calleryasens.str.) and its wing petals are ± equal to the keel in length (vs. much shorter than the keel in Calleryasens.str.).
Although the position of Adinobotrys with respect to its sister genus Glycyrrhiza and the other genera in tribe Wisterieae is not yet fully resolved (see discussion in Compton et al. 2019), it is nevertheless fully supported in being excluded from Tribe Wisterieae and is morphologically distinct from Calleryasens.str. as noted above. Accordingly we make the two new combinations here in Adinobotrys with a new key emended from Adema (2019).
