Passifloraceae, Passiflora foetida, flower and fruit – Gabon, Central West Africa
I believe this is a Passiflora foetida variety that I recently photographed in Gabon. The orange fruit is small but contains edible seeds and pulp with a similar taste as Granadilla. There are quite a few varieties of this species. Here’s another P. foetida I took photos of in S. Vietnam. I didn’t get a photo of the flower, the leaves look different.
And a list of previous posts on other members of the Passifloraceae family.
