Heterostemma ¿ species ? : 7 posts by 3 authors. Attachments (10)
I find this plant at deciduous forests of Northern Konkan: Tungareshwar Wildlife Sanctuary and Sanjay Gandhi National Park.
… attached photos with file names having location and the dates.
I have referred Ingalhalikar ji’s Further Flowers of Sahyadri. The book has 3 Heterostemma species illustrated, of which 2 are very close what I have found.
Page 345 and 348 show H. dalzellii and H. tanjorense respectively.
H. dalzellii is distributed in deciduous forests of Northern Konkan
And, H. tanjorense in evergreen forests of southern hills of Sahyadri.
Today’s find at Yeoor Hills (part of Sanjay Gandhi National Park), I discovered that the central structure of the flower changes colour.
I have started thinking it to be H. dalzellii based on distribution and appearance-wise (earlier had thought it to be H. tanjorense).
Since it is not ditto as shown in the book, ID please … it could be some other species of Heterostemma not known to me. I hope you now get to see the attachments. As put in the message above, I found Heterostemma plants in large numbers — about 10 -12 separate places along a trail in Yeoor Hills, last Sunday (16 AUG)
At Tungareshwar, I have not found the plant this year yet; perhaps yet to flower.
In the photos above, point to notice is the central structure of flower changing its colour from cream to golden yellow to maroon.
To avoid confusion, I have not added photos in which, the petals (I hope, they are petals) are of maroon colour … not sure whether it is just a change due to ageing of flowers OR a different species of Heterostemma. I have collected this plant from SGNP, Borivali Thank you very much, …
This was an important identification for me, pending since long, oscillating between H. dalzellii and H. tanjorense.

Asclepiadaceae (milkweed family) ~ Apocynaceae » Heterostemma dalzellii I think this plant is considered rare and endemic to the region Heterostemma earlier known by Oianthus deccanense, three to four sp. found in Maharashtra H. dalzelli
H. urceolatus
and more I forgot Heterostemma dalzellii Hook.f. Fl. Brit. India 4: 48. 1883. Very interesting generic name. I couldnt make out why they are called Heterostemma. I mean what is the difference in crowns? What I could find from internet …from Owing to the variable nature of the corona in this genus, we have been under the necessity of making its essential character rest on the form and structure of the pollen masses (which resemble those of Stapelia and its allies), and the twinig habit. Each of the species referred to this genus has a form of the crown peculiar to itself: the first has the leaflets dilated, entire, and spreading, with the interior pro-cess similar in form but smaller ; the second has them obcordate, much dilated, with the margins free and overlapping, and the interior process erect flesh j, incumbent on and nearly equalling the gynostegium in height; in the third thej are furnished with a subulate tooth or horn on the back, wmle the interior process is re- duced to a mere gland. Thats really great. Thanks for the information…. Yes … This is also what I found out
This would probably be identified by our members as Heterostemma dalzelli.
Spoke to Dr. Almeida & Santosh Yadav. Their take :
– Heterostemma dalzelli is the only species of Heterostemma that occurs in Maharashtra and is very rare. In fact, Dr.Almeida claimed that he has till date not actually seen a decent specimen.
– what occurs in the Borivali N.P. is most likely a species of Oianthus.
– further study is required.
Sending a few of my photographs. how big are the flowers? 1 inch. Beautiful flower and a truly attractive colour. Does the petal have protusions? Oianthus is now a synonym of Heterostemma (by Swarupanandan et. al., 1989). But we have to find out which spiecies it is? the plant in question is definately not Heterostemma dalzelli. infact we have a altogether different plant of Heterostemma dalzelli which is collected from SGNP. It should be Heterostemma dalzellii Hook.f. as per link: Dinesh Valke
Also Heterostemma decanense (syn: Oianthus deccanensis) is much different. Heterostemma dalzellii
Climber for ID : Yuwaraj Gurjar Indian Flora – facebook group: Posting what is unidentified on Indian Flora facebook group, uploaded by … The climber was clicked in September` 2012, in deciduous forest of Nagla Block – Sanjay Gandhi National Park (Maharashtra). please advice the ID … most probably Heterostemma dalzellii Hook.f. (family Apocynaceae) we had similar discussion on Indian Flora It’s Heterostemma species … The posted Heterostemma species leaves are not matching with H.dalzelli….i suppose .. …, you could be correct with your doubt. This is Oianthus deccanensis. My photographs and our previous discussion on this are available in the archives of this group. My photographs and our previous discussion on this are available at this link It should be Heterostemma dalzellii Hook.f. as per link: Dinesh Valke
Also Heterostemma decanense (syn: Oianthus deccanensis) is much different. . References:
