Please identify this climber – NS 161012:  Photographed on my property at Shahapur. Please identify this annual climber. Have not seen it flowering or fruiting. Could it be a species of Smilax ?


It may be Dioscorea oppositifolia (?), which sometimes, espl in juvenile stage, sports alternate leaves.


Quite likely. Thanks … Sending some of my photographs of D. oppositifolia.


Thanks … for the pictures of Dioscorea oppositifolia.
I have some seed/fruit pictures similar to these from Sinhgad valley as well as from Vetal Tekdi Pune; which may turn out to be the same. Was not aware of the species.


…  bulbils I dont see it May be I am missing them?
all: what is the shrub or? climber in second picture left side with three pointed leaf: ????


It is the Common Mallow [Azanza lampas]. It is just about reaching the end of its flowering season. Sending a few photographs in a separate mail..

Another Dioscorea sp. at CBD Belapur Hills.
Date / Time: 30-6-2013 / 09:40AM
Habitat: Wild
Plant habit: Climber
Location / Altitude: CBD Belapur Hills, Navi Mumbai / 400 ft (Approx)

It looks like D. oppositifolia.
As the plant matures the leaves become sub opposite, at times alternate.


Thanks a lot … for the inputs. I too feel that this could be D. oppositifolia.. Thanks again.

Yes, I strongly feel so.

Dioscorea alata … opposite-leaved dioscorea.


Am sure you meant Dioscorea oppositifolia [the opposite-leaved Dioscorea] my photographs of which are available at this link : efi thread
Dioscorea alata is an exotic …. efi thread

Oh yes … did not had sufficient time to cross-check on this aspect. Only point I was aware that there is perhaps only one native Dioscorea which is opposite-leaved. I am yet to meet this Dioscorea. Many many thanks for the correcting my thoughts.

Dioscorea tomentosa, I suppose.


Are all Dioscorea trinerved?


Leaves in this are simple sir while Dioscorea tomentosa has 3-5 leaflets. Could this plant have simple leaves in younger parts?

Another Dioscorea sp. perhaps?

If the leaves are glabrous, then it can be Dioscorea oppositifolia.


The fruits very much look like D.oppositifolia


Yes, thank you …

Slender terete unarmed stem; 3-nerved leaf with obscure margin, cuneate or rounded or subcordate base & cuspidate or obtusely acuminate apex; broader than long subquadrate capsule suggest it can be Dioscorea spicata Roth. (vide, FBI. vi.291; 

this Dioscorea seems to be D. belophylla or D. oppositifolia !!

I agree with the id Dioscorea oppositifolia.


It may be Dioscorea oppositifolia L./Dioscorea trinervia Roxb. ex Prain & Burkill

Dioscorea oppositifolia !

though indian remote sensing site shows : leaves and fruits are similar to this case
appears in images on bing, bing search engine can not open the nrc site
I tried several times. see if you can open it in google
couple of sites show fruits to be quite different from … pic fruits and Nrsc fruits

MY conclusion: internet is showing confusing characteristics. we need a good reliable source of what is D. oppositifolia. I need to see it


Thanks … I am confused about the species. Some of the google images of D.oppositifolia are showing elongated and pointed leaves while this climber is showing smaller and bit roundish leaves. I checked … image of this sp. from flowersofindia.net.

Is it some other species of Dioscorea ?


I am confused too. that’s why I asked for authenticated description or pictures. I wonder if we have any botanist among our members who may be an expert on Dioscorea, who can teach us// tell us


I think id of Dioscorea oppositifolia L. should be OK as per images herein and as per comparative images at Dioscorea

Fruit shown leaves no room for misidentification ……. Dioscorea oppositifolia indeed !
