Can we identify Stapelia gigantia from stapelia leendertziae (black bell)from the plant , not from the flower? Reason is I have so many stapelia gigantia, even to the point that I have given away quite a few of them to friends and families, but I want to have leendertziae black bell, worries that I will just buy another gigantia, and only can tell it years latter.
These are pictures from the seller, the fist 2, he claimed as gigantia and the last 2 as black bell. tx for assistance.

While I am sure I cannot claim any expertise, to me the two plants look different. And based on the pictures with flowers the second flowerless picture looks more like black bell than it looks like gigantea... does not it could not be something else or a poorly developed gigantea, but based on these four pictures, I would be inclined to take the seller at their word.

Thanks.. Yes, I have just ordered 1 to see how it develop.. and at the same time ordered this one, never seen multiple flowers like this, another NOID, just stated as " multiple flowered stapelia"..
Hope it is real..

I believes that is Caralluma umbellata, one of most circulated Caralluma species in my part of the world. Other Carallumas are difficult to be obtained

Thanks Tofi, I ordered the Caralluma from Payakumbuh, west Sumatrea. I thought I am the only member from Indonesia here..

Ah,... Small globe earth is...
If in the Future your Stapelia turn out to be S. gigantea, Feel free to have Swap things with me, since I have both Gigantea and Lendertziae, I do not have many succulents, but I happen to have those both

You can find some of my plant on instagram under the same name, there i put some of my collections, but not much of cactus and succulents though

Thanks Tofi for the offer, sure if mine turn out to be another Gigantia, then I will contact you, tx.

The black bell has finally arrived, if we put it side by side with Stapelia gigantia, it seems like the black bell will have some candle/ wax texture on the plant ( the black pot), the brown pot is another gigantia that I purchased last month, as the seller said it is a red flower gigantia

From my observation (could be wrong), S gigantea have a more pronounced spike (thorny things?) and also curved inward, they are easier to be seen on young stems. While S leendertziae has short and blunt spike even on young stem. So probably yours are indeed the black bell
