There are three different species of Trichosanthes pilosa as per Catalogue of Life.
Trichosanthes pilosa Lour. is not reported in Checklist of Nepal
From other two, Trichosanthes tricuspidata Lour. fruit look round as per images and details herein. Fruit look similar to Trichosanthes cucumerina var. cucumerina, but seeds look different as per FOC illustration.
Yes, … Flora of China illustrates T.pilosa (syn. T.ovigera Blume- which is mentioned in the Checklist of Nepal). Fruit matches with GBIF– specimen.
POWO and CoL, treat it (T.ovigera Blume) as an independent species, with distribution in Nepal.
I guess it is more close to Trichosanthes cucumerina L.
Yes, in the absence of leaves, I also think this is a better option.
Please have a look at these links.
Trichosanthes cucumeroides (Ser.) Maxim. ex Franch. & Sav. ??
Fruit and seed shapes look different
The Seed shape looks matching and the fruit shape may be variable.
To me, it looks different.
I guess seed shapes are matching with Trichosanthes ovigera Blume.
