Notes: This is a very widespread and variable SE Asian tropical species, and probably the commonest in Thailand. It has been described under a number of names. The degree of pubescence, the length of the calyx lobes and the corolla size have at times been used in attempts to distinguish separate taxa within this complex, but they appear to provide no clear discontinuities.

According to WINIT 680 "every part of the plant is said to be deadly poisonous".
