Calochortus identification by seed capsules

Kipp,

Thanks very much for the information you provided.  I'm still trying to build my intuition about the local Calochortus stands, and this is very helpful.  I still remember my surprise just two years ago of seeing a large stand of Calochortus in the north Santa Anas, in the undeveloped area west of the 241 Expressway, after over a decade of only seeing less than a dozen plants in stands near my home.  

Thanks again for your help.

George

George,

  You aren't going to be able to make that distinction from dried capsules BUT I would say the northern Santa Annas are in the range of weedi var intermedius rather than plummerae. I have observed weedi var intermedius and splendens/davidsonianus in the northern Santa Annas.

  All that said, "weedi intermedius" is just the name for plants that look like a hybrid between weedi var weedi and plummerae (which they likely are). So, despite my suggested ID above, I think the true answer to your question is: you have seeds from the intergrade population of weedi/plummerae called "weedi var intermedius".

Can anyone provide information that would help me identify a Calochortus seed capsule as either C. plummerae or C. weedii?  I've been watching an area in the northern Santa Ana Mountains but was unable to visit the site during the blooming period.  There's nothing in the Jepson manual that jumps out ("FR erect, 4-8 cm, linear, angled"  for C. plummerae and "FR erect, 4-5 cm, linear, angled" for C. weedii).  These two spp. and C. catalinae are the only spp. in the area, and C. catalinae's seed capsule is noticeably different.

Thank you in advance for any information that might be provided.
