Endemic to the unique island ecosystem of Socotra, Withania sphaerocarpa var. grisea stands out due to its distinctive greyish pubescence. This wild plant grows in rocky habitats and dry shrublands, adapting to arid tropical conditions. Its survival depends on the preservation of its restricted island habitat.
This variety grows as a small, branched shrub covered with dense, stellate hairs that give it a characteristic greyish tint. The leaves are simple, alternate, and ovate-oblong with entire margins. Its flowers are small, greenish-yellow, and grow in axillary clusters.
The spherical fruits are fleshy berries. They are completely enclosed in an inflated, papery calyx that aids in wind dispersal.
