I showed a plant of mine, I had grown from a cutting some years ago as Tylecodon wallichii, on the succulent bonsai thread yesterday, and someone chimed up that it was not T wallichii but T cacalioides. Since I am no expert, I just wanted to clear this up so I understand the difference between the two. From what I understood, T wallichii is a common, relatively fast growing plant (which mine certainly has been... growing from a cutting to over 3 feet across in just 8 years in the ground) with bright green leaves that have a flattened (somewhat) side. Plants I have seen labeled as T wallichii have been pretty consistent here in southern California and this species is relatively common and cheap. I have grown dozens of cuttings from this plant of mine (keep hacking off the lower limbs) and they are so easy to grow it seems a crime to even charge $ for them (so I have just given them away).
See the photos below which show not only my plant, but other people's plants which I have understood to be T wallichii.

Re: Tylecodon wallichii versus cacalioides
On the other hand, I learned (probably incorrectly) that Tylecodon cacalioides was a much slower growing plant, far rarer and more expensive and with knobbier branches and more grey, fusiform leaves. The plant I acquired as T cacalioides has certainly been a far slower grower, hardly enlarging at all in 6 years in the ground. Never seen a large one in any other collection, either. Nor have I ever seen this species flower... not sure when it does in fact.
Here are a few shots of other people's Tylecodon cacalioides: Here are mine either in ground, or cuttings in a pot: and here is a shot of cuttings of both my plants... the large, bright green one is the one I know of as Tylecodon wallichii, and the smaller, blue-grey one is what I have learned to be Tylecodon cacalioides... do I have these all backwards??

Re: Tylecodon wallichii versus cacalioides
Hello who-ever and where-ever you are,
Without flowers, Tylecodon cacaloides and wallichii cannot be distinguished. I cannot comment upon vigour and price in the US, but two of your photos look suspicious to me. Your second and last photos show lighter green, flattened(?) leaves and stems without the raised leaf-bases (phyllopodia) and a yellow-ish bark. I suspect these are T. wallichii/paniculatus hybrids?
T. wallichii is the more widespread in South Africa, with a tubular flower that may be dull pale yellow. In the north, the flowers are a little hairy, sometimes with a red tint, and called subsp. ecklonianus. In the Little Karoo, flowers are bright sulphur yellow, longer, with a narrower tube at the base that flares wider at the mouth - this is T. cacaloides.
I am not sure from your photos how many different plants are shown. Are all seven photos after "From my own garden" the same plant? The flower colour seems variable, but this may be just different photo lighting. I was really judging the ID from the deep colour of the fifth photo flowers, but the other look paler and the tubular rather than trumpet-shaped flower is more like T. wallichii. It also has unusually smooth stems without phyllopodia, but shows no sign of T. paniculatus hybridity in the flowers. So I'm no longer sure I gave the correct ID before.
Best wishes,
Derek Tribble

Re: Tylecodon wallichii versus cacalioides
First two T wallichii above are same plant in Huntington.. third is a show plant (not mine) and fourth I mistakenly included as mine (but it's another Huntington plant, different from the first two, but also labeled as T wallichii). Rest are all mine, all the same plant (or cuttings of it).
T cacaloides (not cacalioides?) shots are either some specialty growers or my only plant, or cuttings of it. I have noticed some other plants labeled as T wallichii that do not have the flattened leaves on one side and are totally fusiform, but are brighter green and more robust than T cacaloides (at least was is called T cacaloides). ONly T cacaloides I have ever seen in the ground is my own (everyone else keeps them in pots, due to expense I assume) which may alter their appearance somewhat.

Re: Tylecodon wallichii versus cacalioides
Yes, sorry, should be T. cacalioides throughout.
I've had both in flower in my UK greenhouse this summer and remembered another difference. The flower head of T. cacalioides is more compact than T. wallichii, i.e. some lateral branches are at nearly right-angles to the inflorescence, whereas for T. wallichii, branches all spread at an acute angle. Your bedded/bonsai potted plant does have compact flower heads, so I'm suggesting T. cacalioides again for the ID, despite the colour variation of the photos.
Have a look at some plants in habitat:

Re: Tylecodon wallichii versus cacalioides
If it helps.....all the farmers I've met in Namaqualand who complain about T.wallichii as poisonous to their livestock, they dig out the plant with grey, roughish leaves and the knobbly stem.lzrddr wrote:....do I have these all backwards??
