Desmodium scorpiurus from Borivali National Park : VG-JAN-02 : 6 posts by 4 authors. Attachments (2) Sharing some images of Desmodium scorpiurus (Sw.) Desv. flowering in the north end of the Sanjay Gandhi National Park (aka Borivali National Park) in Mumbai.
This herb is uncommon in SGNP and was reported only from the fringe areas of the forest during the Botanical Survey of India’s floristic survey of SGNP (published in March 2005).
“Though not collected from the National Park proper, its occurrence there cannot be ruled out since the localities cited above [‘Aarey colony & Thane’] are in close vicinity of the park.” – p. 204, Flora of Sanjay Gandhi National Park (by SG Pradhan, BD Sharma & NP Singh), BSI, 2005.
Photographed today near Gandhi Tekri in Borivali National Park, North Mumbai.
Had posted some photos of all the plant parts last year (and it was identified by …). These can be seen in the thread linked herewith. Many thanks … for sharing this plant; and thanks to … too. I have seen them some years back in scrub forests on outskirts of Thane, and I am sure, will need to be correction in my notes. It looks as if this plant is on the way to becoming a very widespread weed due to its adaptability.
Ten years ago it was much less common but I seem to see it all over the place these days in the Mumbai area. There is no mention of it in Cooke’s flora. It is native to tropical regions of America. Thanks … for your observations on the ominous dispersal of this plant over the years in and around Mumbai. I haven’t come across any dense populations yet, just some sparse growth here and there. I too have seen this plant in lawns of corporation gardens in Pune, growing gregariously.        Fabaceae (Faboideae) Fortnight :: Desmodium scorpiurus :: Thane :: DVOCT68 : 1 post by 1 author.

Thank you …, will check the alternative.
Your other posted plant also appears to be Desmodium scorpiurus an increasingly very common plant both in Alibag and Virar areas.
The pod in your image is too immature to be representative.
I cannot comment on the species rooting at the nodes and could not observe this character in … earlier post.

Desmodium scorpiurus (Sw.)Desv. By … as per another thread. Genus Desmodium and Pycnospora are differentiated on their pods, being jointed or not (distinctly) jointed respectively. The immature fruit seen here does not seem jointed.
… mentioned (same thread that has … comment) in his post that D scorpiurus is ‘freely rooting at nodes’ whereas here there was no rooting at nodes.

If pod is inflated it is almost close to Pycnospora luetescens; there some deviation in the leaf shape.
Thank you … I will appreciate if you could explain the deviation in leaf shape and whether the lack of joints in the pod is not enough evidence of Pycnospora (as there were no mature pods on the plant to see whether they were inflated or not.)
The leaflets are normally obovate, but they are not here; pod inflated.; in brief, it has leaves and pods like Crotalaria; flowers like Desmodium
