Seemingly distinguished from other species of Ipomoea by the dense, yellowish hirsute indumentum on all vegetative parts and short glabrous filaments. The fruits of this species are as yet unknown, and when they are discovered it may prove that this is actually an Argyreia. A number of yellowish hirsute species of Argyreia with purple-red flowers are known from the Indian subcontinent and northern Myanmar that could well range into Xizang. Only further collections will illuminate the true generic relationships of this species.
