Hi Jane,
Several species of Calochortus are known to hybridize in the wild where
species distributions overlap. Attached is a picture of a list of hybrids
compiled in Gerritsen & Parson's book titled Calochortus. I'm sure there
are more than those listed.
If you are able to send a picture, I'd love to take a look.
Best,
Adriana
