Known only from a single collection made by Balfour on Jebel Ma’alih in the 19th century. Although insignificant and easily over-looked the site where this mysterious plant was originally found has been surveyed many over the last one hundred years and consequently it must now be considered Extinct.

Habitat and Ecology [top]

Habitat and Ecology:Annual on dry hill slopes near Galonsir [Qallansiyah] Balfour 1888.

Only one other species of this predominantly Meditearranean and North African genus is recorded from the region, V. microcarpa Lois from Kenya and Ethiopia. However, V. microcarpa is widespread in the Mediterranean region and it is not clear whether it is native to or introduced into tropical Northeast Africa. The status of the Soqotran V. affinis, a rare Mediterranean outlier, which is only known from a single dried specimen, needs further investigation. For the time being it remains an example of a rare Mediterranean–Soqotran geographical disjunction and has interesting biogeographical implications.
