Abstract

The paper presents Aspilia kotschyi (Sch.Bip. ex Hochst.) Oliv. (Asteraceae), a newly recorded genus of vascular plants, during the fieldwork in Fayfa region in the Southwest of Saudi Arabia. Flora books and scientific research papers dealing with the flora of Saudi Arabia have not mentioned any species of Aspilia genus. The taxon was found for the first time in Saudi Arabia, which makes a new addition and significant contribution to the flora of Saudi Arabia. The plant was seen near cultivated terraces and collected in September and October 2020 from Fayfa mountains, Jazan province, Southwest of Saudi Arabia. Morphological description, taxonomic remarks, distribution map, plant illustration, and plant photographs are provided.

Keywords: Aspilia kotschyi, Asteraceae, Arabian Peninsula, New record, Fayfa region

1. Introduction

Aspilia Thouars is native to Africa, Southern America and Yemen. The genus belongs to the family Asteraceae Bercht. & J. Presl. Aspilia plants are annual or perennial herbs, less often shrubs, Leaves opposite, scabrid or hispid, Capitula terminal, solitary or in lax cymes, or axillary and in congested corymbs, radiate; phyllaries 2–3-seriate, the outer herbaceous, the inner scarious; receptacle with conduplicate paleae, Ray florets with the ray 2-lobed at apex, with or without style, not producing mature achenes; disc florets tubular; anther bases obtuse or shortly sagittate, thecae and appendages often black; style branches gradually narrowing, pubescent at margins, fruits achenes obovoid, compressed, pubescent; pappus a laciniate cupule, often with a few setae (Beentje et al., 2005).

Aspilia Thouars is represented by 125 to 140 species (Ogundipe and Adegbite, 2008, Komakech et al., 2019, Okwuonu et al., 2017). The genus Aspilia has 261 scientific names for species; 103 are accepted species names (The Plant List, 2020).

Aspilia genus is native to Africa, Southern America, and Yemen, according to the flora of tropical East Africa (Beentje et al., 2005). There are 21 species of the genus Aspilia recorded from Africa (Wild, 1966).

Some authors have compounded the genus Aspilia, and considered it as a synonym of Wedelia Jacq. Still, others request more study to decide (Tadessa, 1999, Kadereit and Jeffrey, 2007). The distinction between Aspilia and Wedelia is in ray florets' capacity to develop mature (Adams, 1956).

The name kotschyi in Aspilia kotschyi (Sch.Bip. ex Hochst.) Oliv. is after Karl Georg Theodor Kotschy (1813–1866), an Austrian botanical explorer and plant collector. He collected thousands of plant specimens from Iran, Sudan, Cyprus, and northeast Africa (Edmondson and Lack, 1960). Within Aspilia, some characters such as the color of ray florets are detected; This leads to species varieties such as var. kotschyi, and var. alba (Mesfin, 2004) and even to different species such as A. kotschyi and A. helianthoides (Wood, 1997).

Aspilia kotschyi is recognized in many research studies and plant taxonomic sites. A. kotschyi var. kotschyi is a synonym of A. kotschyi (The Plant List, 2020).

2. Materials and methods

A field trip to Fayfa region was conducted searching for unknown and undescribed plant species on 2 September 2020. The plant was observed in two geographical locations, predominantly agricultural mountain terraces, between latitude 17.2326017 and 17.229361; Longitude, 43.0772566, and 43.075971; elevations between 1055 and 1130 m (Fig. 1).

Plant observations and measurements were made on both vegetative and morphological characters compared with taxonomic key and description in the published sources (Mesfin, T. (2004)). Botanical identification was confirmed at King Abdulaziz University and the University of Albaha by using available references and literature (Mesfin, 2004, Wood, 1997). The plant species was deposited at the herbarium of the University of Albaha, department of biology, Baljurashi, under the name (Alfaifi, 9-2020), duplicates are available in King Abdulaziz City for Science and Technology Herbarium (MUZ), Riyadh, under the name (Al-Namazi and Alfaifi, 10-2020), for future references.

Literature and herbarium searches (Collenette, 1999, Chaudhary, 1999, Chaudhary, 2000, Chaudhary, 2001, Qashash, 2007, Al-Surour, 2018) revealed that the plant and the genus had neither been reported nor collected in any herbarium in Saudi Arabia before.

3.5. Distribution and habitat

Widely distributed in tropical Africa. It is native to Angola, Benin, Botswana, Burkina, Cameroon, Central African Repu, Chad, Congo, Eritrea, Ethiopia, Gabon, Guinea-Bissau, Kenya, Mali, Mozambique, Nigeria, Senegal, Sudan, Tanzania, Togo, Uganda, Yemen, Zambia, Zimbabwe (POWO, 2020). In Saudi Arabia, the plant grows successfully in moisture soil on a mountain terrace following a rainy season. Flowering and fruiting were observed from August to October.

3.6. Conservation status

Not Evaluated, the plant is generally rare in its locality, only seen twice. Intensive fieldwork is highly recommended for further information on its density and frequency to get a good conservation status for this newly discovered plant.

4. Discussion

In Arabian Peninsula, only one species of Aspilia (A. kotschyi) and one subsp. (A. helianthoides subsp. ciliata) are recorded from Yemen (Wood, 1997, Al-Khulaidi, 2013). Aspilia kotschyi can be utilized economically (e.g. medicinal) (Adamu et al., 2018); another plant of this genus (A. africana), is widespread in Africa and considered as an important economic plant, and is used to treat numerous disease conditions such as healing of wounds and stop bleeding (Komakech et al., 2019, Oluyemi et al., 2007).

Fayfa region is very rich in flora and characterized by high plant diversity. Few new plant species for the flora of Saudi Arabia were discovered from this region. It is expected with the extra exploration of the vegetation and the flora of the region, to discover new plants that have not been previously recorded in the Flora of Saudi Arabia and the Arabian Peninsula.

To conclude, this study has been recorded the occurrence of Aspilia kotschyi in Saudi Arabia for the first time. The plant is characterized by its hispid indumentum with simple, opposite, sessile leaves and dark red flower colour. The present work will aid in the evaluation of the plant conservation status in Saudi Arabia and the Arabian Peninsula in general.
