Arctostaphylos Adanson subg. Arctous A. Gray in A. Gray et al., Syn. Fl. N. Amer. 2: 27. 1878
Species 3 or 4 (2 in the flora).
The genus Arctous differs vegetatively from Arctostaphylos in having leaves with winged petioles and crenate to serrulate margins, fruits that are bright red or black and juicy (in Arctostaphylos the fruits are mealy or granular), and only five nutlets with hard, smooth endocarps (in contrast to Arctostaphylos, where the fruits have ten sculptured nutlets). Arctous has flowering buds that develop in the spring, as opposed to Arctostaphylos, in which buds form in the summer and autumn and lie dormant during the winter. Phylogenetic studies employing molecular methods place Arctous as the sister group to Arctostaphylos. Both species of Arctous in the flora area turn bright orange-red in autumn and are suitable for the alpine or rock garden.
