Hello.
Just wondering if any local planeteers of the San Gabriel / San Bernadino region wanted to go on the hunt for a variety of Ribes divaricatum said to be extinct, however I think it's too soon to give up just yet. I am talking about the var. parishii, which has pink/red petals and so is simple to ID. The other varieties should not even be growing near this locality, but in any case I have included the key below. If plants are still there, they should be in flower now. Obviously remember the location if you should find some survivors, so seeds can be harvested in a few months time. I think it would be a very valuable find, as this variety would be much more adaptable to warmer climes. Regards
Here is a key to the subspecies (Sinnott, Q., 1985, Rhodora 87(850):189-286)

AA. Filaments more than 5 mm long; petals 2-3 mm long, white or red-pink; style 8 11 mm long
B. Calyx tube 1.7-2.7 mm long; petals white; coastal areas from Queen Charlotte Islands southward to southern Oregon
