A reconsideration of the generic circumscription of Heterostemma Wight & Arn. (Asclepiadaceae) and a new species from India by K. SWARUPANANDAN, N. SASIDHARAN and JOSE K. MANGALY- Botanical Journal of the Linnean Society Volume 101, Issue 2, pages 249–259, October 1989-
AbstractHeterostemma Wight & Arn. (Asclepiadaceae) and a new species from India. Heterostemma vasudevanii Swarupanandan & Mangaly, a new species belonging to Asclepiadaceae is described and illustrated. The discoid-urceoloate corolla and the staminal coronal scales with a ventral appendage show this species to be intermediate between the two genera Heterostemma and Oianthus. Basically, the concepts of the two genera differ only in a pair of characters which, in the light of the new species seem not to be particularly diagnostic. On this basis it is proposed to merge the two genera together, by reducing Oianthus as a section under Heterostemma. Consequently, three new combinations are proposed. Examination of recent collections extends the distribution of what was O. decanense, earlier considered to be endemic to Maharashtra, further south to Kerala.

I have updated eFI (efloraofindia) page on Heterostemma

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.

Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.

If someone can provide complete list of Indian species with source references it will be wonderful.

Any comments/ corrections are welcome.

I have added the list of species of Heterostemma in India based on the reference (Karthikeyan et al. 2009) wherein it is listed in Asclepiadaceae. However, since eFI accepts families according to Plant List/ APG system it is in Apocynaceae.


Pl. go through Heterostemma page (‎‎‎Apocynaceae) with images of species in efloraofindia (done by me).

If you find any mis-identification, pl. let us know.

If anybody can send images of other species of this genera (for incorporation in the website), it will be really nice. Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
