Each flower is 1 to 1.5 inches wide, fragrant and greenish-white. Petals are absent but four greenish sepals present which are oblong-ovate and covered with soft down.

Natural history

C. gouriana is a vigorous climber spreading on thickets and climbing on trees. Principally in tropical and subtropical forests.[5] It occurs up to 5,000 feet (1,500 m) in the Himalayas; in the hilly districts of the peninsula it occurs between 1,000 feet (300 m) and 3,000 feet (910 m).[9] Flowering takes place from August to February, while fruits appear from September to May.[5]

Medicinal uses

C. gouriana is recognised as a medicinal herb in traditional medicine and amongst tribal communities. It has been investigated for its medicinal properties.[10] It has been found to possess steroids and emodins as secondary metabolites.[11]

The bruised leaves and stem act as a vesicant and are poisonous.[12] In Ayurveda, the leaves of the plant have been used for treating puerperal fever and bruises.[13] Leaf paste is applied to wounds of cattle by Jatapu, Khond and Savara tribals of Andhra Pradesh, India.[5] The crushed leaves and stems are also used for treating lice in India.[11]

gollark: Are syscall numbers scarce somehow?
gollark: I don't see the value in packing multiple different things into one syscall because the arguments happen to be the same when the kernel will have to check and dispatch to different things *anyway*, and user code also has to use a specific known form anyway.

gollark: yes.
