The Calochortus, section Mariposa species are at their peak of flowering here, and I'm trying to verify the identity of one that has been quite successful in the bulb frames. I grew it from seed many years ago under the name Calochortus argillosus, but later became uncertain about its identity. I was just sitting down with the Jepson Manual (I don't yet have a copy of the new book on the genus, though I'm expecting one any time now) and a flower. When I work through the long key (all the way to the end!) I do come up with C. argillosus, yet in the species description in the text, this species is said to have a nectary that is not depressed. My plants have depressed nectaries, and I got to argillosus in the key via a step specifying depressed nectary, so apparently the key and the text disagree. An unusual characteristic of the flowers here, not mentioned in Jepson or in Frank Callahan's discussion in Bulbs of North America, is that the zone that's yellow on the upper (inside) surface of the petals shows greenish on the lower (outside) surface. Can someone help me sort this out, please? I have scores of these bulbs and would like to distribute some. They're very pretty and increase fast by stem bulbils.
