Cucurbitaceae Week: Benincasa hispida from Delhi??? and California:
I am not very sure whether the plant photographed from Delhi is Benincasa hispida. Please give your opinion. It was cultivated in Wazirabad along banks of river amuna in Delhi.
I am also enclosing photographs of Benincasa hispida, the white pumpkin sold in California markets.

Pictures from Chhattisgarh.

The fruits are very clear in your photographs, as they are in mine from California. I am not very sure about mine from Delhi, though I had tentatively identified them.

Hooghly today – Benincasa hispida (Thunb.) Cogn.??? : Attachments (15 + 8). 3 posts by 2 authors.
This one is growing about 150 meters away from my home. Leaves and flower size (diam.) are about the same of my another post

Yes … We found lot of these in Jim Corbet area recently, almost every house had it along their fences, sometimes appearing almost wild.

Thank you very much for confirming. The fruit is locally known as CHHANCH-KUMRA (CHAL-KUMRA / KUMRA in old lit., attached here).
It is interesting to note that Dr. Prain equates it with Cucurbita pepo of Flora Indica. Also, Voigt in Hortus Suburbanus Calcuttensis and maybe Piddington too.
But, far more surprising is that Dr. Hooker equates Cucurbita pepo of Flora Indica with both, Benincasa cerifera Savi and Cucurbita pepo DC.

The Ash gourd– a very common vegetable here. Used in the preparation of sambar. The raw juice is used for acidity / gastric  problems. Ash gourd is also used in rituals  as well.

I guess it is used to produce ‘Petha’ also.

I think so.
