Looking for info, sources for Mexican curbits

[gilbert]

I’m interested in learning more about some squashes that are native to Mexico; Cucurbita pedatifolia, C. X scabridifolia, C. radicans, and C. lundelliana. (This last is an annual.) All I know about them is that they grow wild in Mexico.
Does anyone have any experience with these plants? Is the fruit at all edible? Do the plants have a strong smell or other undesirable qualities? What ecosystems do they inhabit?
Does anyone know of a source for seed of any of these species?

I'm thinking about using them in a breeding project.

None is listed in Cornucopia II, which is where I go to check for anything edible, anywhere in the world.

Cucurbita lundelliana is listed in the Royal Horticultural Society's Index of Garden Plants, which means someone, somewhere,
has been growing it. My version was published in 1994.

You've probably already got its description, but I'll copy it here anyway:

Ann to perenn, sparsely hirsute or glab. St. prostrate or scandent, simple. Lvs 5 - 9 cm, broadly ovate,, cordate, lobes 5,
obtuse, short-pilose above. Fr. c 7X6 cm, globose-oblong, green or yellow-tinged.

That does not sound promising.

For this year I'll probably have to do without in any case.
