  These look to be C. nudus to me. C. minimus is usually pale white. The ranges of both are certainly close to Lassen. What makes you think they may be C. minimus or a hybrid?

We recently had the good fortune to spend a few days at Mt Lassen National
Park in northern CA.

On August 20th, on the trail from Cold Boiling Lake to Crumbaugh Lake, I
saw the attached Mariposa Lilies.

They were growing along a wooded, partially sunny trail a little below

As far as I can tell, they are C minimus, Sierra Mariposa Lily.

However the plant list for the park only lists C. nudus, Naked Mariposa

The park naturalist indicates that without a specimen, it is impossible to
tell whether this is a new species for the park (C minimus),
or a hybrid of C minmus and C nudus.

Do any of you have any thoughts on this?   I could not find anything
published online about hybrids of these species and how to identify them.

Any help would be appreciated.
