Re: Tephrocactus alexanderi and recurvatus

Thanks Tony, Mike.
Then T alexanderi is going on the label.
The large one came as T. fiambalensis, by the way.

Coincidentally, I'm seeing Martin tomorrow, so I'll see what he has to say too...

Re: Tephrocactus alexanderi and recurvatus

It looks just like Fero's :grin: (tu) Thanks!

Here it is with my Tephro alexanderi (right) for comparison. So, are both alexanderi?

Re: Tephrocactus alexanderi and recurvatus

Thanks Tony. The plant in question does have small segments, and is well clumping, but the spines while recurved are not so long. And I was given it yesterday - so I am not sure how hard it is to grow yet! :smile:

Tephrocactus alexanderi and recurvatus

Mike, all Do you have a good way of distinguishing T alexanderi and T recurvatus? The basic difference seems to be that the former has erect spines and the latter recurved ones - but one of the pictures in "Small Opuntias" shows an alexanderi with rather recurved spines. So, there must be more to it...

Re: Top shelf plants???

How about Hildewinterias? In time, it will save you having to brush your hair before walking out to the greenhouse. And you should get to see some super flowers.

Re: Mystery plant

Yes, seems to be Lenophyllum texanum.

Its problem is that the leaves fall of at the slightest touch.
I think I got them all when removing it. :shock:

Thanks for the warning, everyone.

Re: Mystery plant

Yes, no idea of the correct name, but this THING is as bad as Oxalis, and definitely worse than Bryophyllum sp in the glasshouse, and I would recommend urgent removal and eradication. I have found it to be frost hardy in rural Hampshire for at least the last 10 years! DESTROY !!!! Gulp. Quarantined...

Re: Mystery plant

Lenophyllum? Yes, I was reminded of that. I have L. guttatum and L. reflexum, and find neither specially easy to grow. Perhaps it did come in from elsewhere, but I repot plants as I acquire them, so it is unlikely to have come in unnoticed except as a seed. If so - why would it be in the bottom of ...

Re: Rebutia heliosa RH291

I have a few Aylosteras with stripey petals, and they are fairly consistent in doing it each year, although the strength of striping can vary somewhat from petal to petal.

I'd suggest haagei has broader, rounder tipped petals. Have a look at the flower tube. It's much thinner in heliosa.
