Fritillaria micrantha

Last week I posted a note about Fritillaria recurva and its relatives, 
which form a distinct group of western North American species typified 
by the widespread Fritillaria affinis. One I mentioned was Fritillaria 
eastwoodiae, which looks like a miniature F. recurva on a tall scape. 
Near that group of plants I have another cluster which I thought was 
more F. eastwoodiae, the plants being indistinguishable, but they were 
only in bud. I was wrong. Today the first flower on the second group 
opened, and proved to be Fritillaria micrantha, which I'd never seen 
before. It is native to the western lower elevations of the central 
Sierra Nevada of California, including Yosemite National Park. Its 
coloration outside (the lower surface of the tepals) is much like the 
brown-green F. affinis, but inside it has a pretty pattern with zones of 
bright yellow. The flower is about 2 cm in diameter and is open, not 
tubular like F. recurva and eastwoodiae. (By the way, these plants do 
have labels, which are probably buried by the gravel topdressing. They 
are planted directly in a raised bed, not confined to pots.)

I'd have to search far back in my seedlists to find out how long ago I 
sowed the seeds of these plants, but it was more than 6 years ago. I 
wonder if it's just maturity that brought all of them (about 6 
individuals) to flower this year, or if our unusually warm 
December-January was a factor. Certainly some other denizens of the bulb 
house (which is unheated and open on the sides) are flowering unusually 
heavily this spring. I'm grateful for that, since there have been a 
number of visitors to see them, including some new acquaintances who 
attended a party for Kit Strange, a staff member working in the bulb 
collection at Kew.
