Aspidistra umbrosa is a species of flowering plant. Given it was described from an unclassified Aspidistra specimen from another study, neither its distribution nor habitat are known.[1]

Description

This species is a perennial herb. Its rhizome is creeping, and measures 5 millimetres (0.20 in) in diametre. Its leaves are 1.5 to 2.5 centimetres (0.59 to 0.98 in) apart, its strong petiole measuring about 30 to 35 centimetres (12 to 14 in); the lamina is obovate and acuminate, measuring about 30 by 10 centimetres (11.8 by 3.9 in).[1]

Its peduncle measures 0.2 to 0.5 centimetres (0.079 to 0.197 in) long; its perigone is campanulate and purple, measuring 15 millimetres (0.59 in) long and 7 millimetres (0.28 in) in diametre, possessing 6 lobes, each with 2 keels. It counts with 6 stamens, while its anthers are subsessile and linear, and measures 4.5 by 1.5 millimetres (0.177 by 0.059 in); the pistil is thin and 10 millimetres (0.39 in) long, while the ovar is inconspicuous. Its style distally widens towards the smooth stigma, which measures 3 millimetres (0.12 in) in diametre.[1]
