Triteleia peduncularis and offsets from corms

Writing my last post about vegetative increasing of Tecophilaea led me to 
the following thought so I am posting it separately.

We had a discussion earlier about a form of Triteleia ixioides from Table 
Mountain that does not offset whereas other Triteleia ixioides produce many 
corms. I find that growing many of the cormous  species in the Themidaceae 
family there is a great variation in the ones that produce offsets even in 
the same species. The form of Triteleia laxa that is so often sold, Queen 
Fabiola, produces many cormlets which is no doubt the reason it is a 
popular cultivar to sell as it is quick to increase. Some of the ones I 
grow increase very modestly. We have discovered Triteleia peduncularis 
growing on the  Mendocino and Sonoma coast this year. It has to have been 
here before, but I can't remember seeing it. We had late rains so maybe 
that was the difference. Perhaps it has dried up before it bloomed before 
as there were still a few finishing blooms on the 4th when I looked for 
seed. This Triteleia is very low with much shorter pedicels than the ones I 
grow and have seen before which ruins the key I made a number of years ago 
as a long pedicel is usually the distinctive way to identify this species. 
Many of the pedicels were about the same size as the flower and some were 
almost but not quite twice the size of the flower. The pedicel elongated a 
bit once the flower had finished, but even when we went back later and 
looked at these plants the pedicel was often much shorter than I've seen 
before. The ovary was yellow, but when I returned three or four weeks later 
had turned to green. It was a good example for me of why keys are so 
difficult. To find characteristics that fit all forms of a species can be 
tricky. It partly depends on when you look at the plant besides the 
variation in forms. In the future no doubt we will just point our dna 
machines and push a button and the species name will appear so we won't 
need to know the identifying features.  ;-) The T. peduncularis I grow has 
multiple baby corms every year. I wonder if this form increases 
vegetatively. There didn't seem to be a lot of leaves around the flowering 
clumps, but they could have died back by now. If you are interested in 
seeing this new form of T. peduncularis I've added it to the wiki:…
