2 (1) Capsule spines glabrous or hairy at base only; leaf blade hairs mostly unbranched, occasionally few-rayed on main veins; flower bud nearly glabrous. T. annua
+ Capsule spines uniformly hairy; leaf blade hairs mostly obviously stellate, abaxially tomentose; flower bud obviously hairy T. pilosa
.
As per efi link :
If fruit are about 2 or more cm in diameter then it points out towards Triumfetta pilosa Roth
If the fruit are smaller about 1 cm or so then it can be Triumfetta annua.

Came across this prostrate climber at Helwak (Koyna nagar). 22-01-2010.

it looks like Triumfetta annua (Tiliaceae) for me.


To me it seems fruiting Passiflora foetida.


I assume that the fruit are about 2 or more cm in diameter then it points out towards Triumfetta pilosa Roth.
Flr & frt: September-October.
Locality: Khandala, Maahabaleshwar.
if the fruit are smaller about 1 cm or so then it can be Triumfetta annua (i have observed this T.annua but the fruit does not look like the current pic)


This is Triumfetta sp but the species as said by … will depend on the fruit size [ <=2cm pilosa; >=1cm annua] to confirm about the species … will have provide us with approx size of the fuit. Fruit of Passiflora sp is glabrous by nature and it is partially covered by mesh life chlorophyllous wraping which is fribiller by nature as the petal fall off early during the fruit development. attaching a photo of the Passiflora sp. more over the leaf chracter doesn’t match in Passiflora leaves are 3-5fid viscid -hairy.


I think T. annua as per keys & illustrations at
http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=200013658
http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=133837


Compared to T. annua, here the spines are clearly longer, and they also seem to be more in number, at least looks denser at centre, I believe it is T. pilosa.


No, …  That is not the key. Pl. Check the keys in the link I have given link to.
Rather nature of hairs on the leaves are more important along with size of the plant etc.
Pl. check the images of all posts of both species at efi pages, which I have just sorted out.


Yes, you are right, …, following keys at BSI Flora of India with details & keys (Volume 3- 1993)
Stem (which is one of the keys) does not seem to be glabrous.

However, I find keys given in Flora of China as below are much better in sorting out these two species (applicable to India):
2 (1) Capsule spines glabrous or hairy at base only; leaf blade hairs mostly unbranched, occasionally few-rayed on main veins; flower bud nearly glabrous. T. annua
+ Capsule spines uniformly hairy; leaf blade hairs mostly obviously stellate, abaxially tomentose; flower bud obviously hairy T. pilosa

I can see Capsule spines uniformly hairy; leaf blade hairs mostly obviously stellate, abaxially tomentose in … post although the images submitted are of very small size.
