About

Begonia samhaensis is a species in the family Begoniaceae. Similar to Begonia socotrana but separated by the asymmetrically ovate leaves and the unequal tepals in the male flowers; outer tepals broadly orbicular, 1.5–2.2 × 1.7–2.5 cm; inner obovate elliptic, 1.4–2.0 × 0.8 × 1.4 cm.

Where it grows

It grows in damp and shady cracks in north-facing limestone cliffs, 600–700 metres (2,000–2,300 ft) on the island of Samhah in the Socotra Archipelago, Yemen. It grows on north facing cliffs on the summit pinnacle and escarpments of the limestone plateau at the centre of Samhah island. Its area of occupation is less than 10 km2. The cliffs where it grows catch precipitation and mists principally from the NE monsoon and represent a unique habitat on Samhah island.
