These slender tapered seedpods, which in Burmese are called kyat paung thee, belong to a plant in the milkweed family.

It has the botanical binomial names Cynanchum louiseae, Dregea volubilis and Vincetoxicum nigrum, and is commonly known in English as Black Swallow-wort, Louise's Swallow-wort and Black Dog-strangling Vine, and nicknamed Green Wax Flower.

In Myanmar, these pods which are tightly packed with seeds attached to puffy fibers (fig.), are used in home cuisine.
