Pl. go through ‎Marsdenia 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.
