Talk:Arctostaphylos hookeri

A. franciscana and A. montana ravenii now seem to be separate species from A. hookeri.

According to the Fish and Wildlife Service in the Federal Register notification of its plan to list A. franciscana as an endangered species, A. franciscana and A. montana ravenii are separate species from A. hookeri.

At one point Arctostaphylos franciscana and A. montana ssp. ravenii, along with A. montana ssp. montana (Mount Tamalpais manzanita), were considered to be subspecies of A. hookeri (Hooker's manzanita). However, recent taxonomic revisions have established A. montana ssp. ravenii and A. franciscana as separate species. These revisions have been based primarily on genetic comparisons, including the fact that A. franciscana is diploid (with 13 pairs of chromosomes) while A. montana ssp. ravenii is tetraploid (with 26 chromosome pairs) (Service 2003, p. 95; Parker et al. 2007, pp. 149, 150; Chasse et al. 2009, p. 6).

So, it looks like we may need to create some separate articles for these Manzanitas. Rupert Clayton (talk) 05:02, 9 September 2011 (UTC)
