Notes: In the study area, this vine can be compared to I. quamoclit due to its red, hypocrateriform corolla with exserted stamens. However, they differ in the leaf shape and sepal characteristics: I. hederifolia has entire or 3-lobed leaves and sepals with a subapical rostrum, whereas I. quamoclit has pinnatisect leaves divided into 8–15 pairs of linear segments and sepals that are smooth, without a subapical rostrum.
