Question

What is the vivid green, vaguely-mango-shaped "fruit" that is covered with green spikes that grows in the south-facing canyons of the San Gabriel Mountains in S. California? We saw some up in Big Santa Anita Canyon today. They grow from a plant that looks either like a pea plant or a grapevine. (I put quotes around fruit as I suspect that's what it is, but I'm not sure!)

Hi Meegrob,

It sounds like a Wild Cucumber... see the link below (and scroll down to the fruit).

I hope this is of some help to you.
