Calochortus amabilis

Jane,

In my experience, populations of Calochortus amabilis plants 
containing many individuals displaying brick red markings on their 
tepals are extremely common in the Inner North Coast Range north of 
San Francisco across multiple counties (see attached photos). There 
are probably populations without any markings but I don't remember 
the last time I encountered one.

Any chance of seeing a picture of your putative hybrid in flower? It 
sounds very interesting.

Nathan
