i think we should id it;s family first
Dioscoreaceae and Vitaceae are both very possible

I think it's Not Dioscoreaceae.
Because of the vein. DIOSCOREACEAE will have multiple curved central vein.

it must be some dicotyledon family.

Vitaceae will have tendril or butterfly-egg-like droplet grow on new leave.
Present of these characteristic can confirm it's Vitaceae.
But Absent of these characteristic can;t rule out the possible Vitaceae.
From taiwan. hot humid subtropical island.
Pachypodium grow like weed here.
(not really, but u get the idea hot sunny rainy)

Hi Ralph, and all
I'n not convinced that the vein pattern is always an easily distinguished feature. I have D. quartiniana (or at least that's what the seed supplier stated) and it looks very similar to your plant Ralph, both in leaves (apart from being five-lobed rather than three-lobed), leaf venation and tubers. The tubers, like some other Dioscoreas, tend to grow down and out of the drainage holes.
Cheers

What do you mean by yam? It's a rather ill defined term (which is why Latin names are preferable). Yam usually refers to Dioscorea species of one kind or another, but I agree with kohinoor's argument that it is unlikely to be a Disocorea because of the venation. Monocots usually have parallel veins, while dicots typically have reticulate (branching) veins. It's also not oca (Oxalis tuberosa), or a sweet potato (Ipomoea batatas) which are sometimes called yams.

I went through Wikipedia's entire list of root vegetables (excluding bulbs, which it clearly isn't), and it doesn't match any of them, so I am no nearer to finding out what it might be.

I'm pretty sure it arrived as an unexpected extra in some cactus or succulent I bought, a long time ago, which is why I was asking here...

Thanks Mike. I do have to agree that the veins are not parallel in D. quartiniana, so perhaps I am being too hasty in writing Dioscorea off as a possibility.

If you would like some to try, I'm happy to send you a few so you can let us know if they are edible or poisonous! :lol: :cool:

Seriously, send me a PM with your address and I'll pop a few in the post. Even better if you have something interesting to send back...

Jane

I'd be very pleased if it is an Aristolochia - they have amazing flowers...
