In preparation of an article about this species I need some information.
I hope you will react when you think you know one or more answers on the
questions put to you here, or anything else you think is worth knowing about
Euphorbia horwoodii. Thank you very much!
There seems to be more than one
taxa involved for Euphorbia horwoodii known in cultivation. I grow four
Seedlings of Euphorbia horwoodii are reported to form a sphere in the
juvenile stage and form sidearms later. This form is pictured as a grafted
seedling, and you can see the sidearms are just about to develop. The
other picture of a seedling does not form a sphere at all and grows as
a branch right from start.
Questions: 1. Are there more clones in cultivation
than these ones?
2. Are these two types of flowers and seedlings related to certain localities
3. Are they perhaps hybrids?
4. Who knows what B&L stands for and what are the locality-data
of this plant?
Clone 1 is probably the oldest in cultivation and the most robust one
of all. As you can see the cyathium is quite long with a long exserted stigma
Clone 2 is only slightly smaller than clone 1, also of unknown origin.
Clone 3 is the B&L 587 clone. This is the weakest one and remarkable
for its slightly bend spines.
Clone 4 originates from Arid Lands are has a blue body colouring. The
cyathia appear to be much more normal in appearance than clone those of
Flower clone 1
