I have a little Leucosidea sericea I planted last year in my yard, I got it at the Arboretum in Seattle (talk about an impulse purchase).
I thought I would upload a photo, but I do not see it in the database. I found it in The Catalogue of Life. They do not seem to have any synonyms listed.

Hi Mary,

Here you go: Leucosidea sericea

Turns out we didn't have it or either of its two synonyms in the database. It's a single species genus, so technically the entire genus was missing!

Thanks!
