GENUS INDEX

GENUS CODE: RHODO
GENUS SCIENTIFIC: Rhododendron
GENUS AUTHORITY: L.
GENUS COMMON: Azalea
GENUS SUMMARY: A genus of about 860 species, shrubs and trees, mostly north temperate (centered in Himalayan Asia). Molecular evidence appears to show that Menziesia should be included in Rhododendron, and is actually closely related within Rhododendron to R. vaseyi (Goetsch, Eckert, & Hall 2005; Kurashige et al. 2001); while the urceolate corolla is rather anomalous in Rhododendron, many other characters ally Menziesia with basal clades in Rhododendron s.l.
GENUS IDENTIFICATION: Identification notes: This key makes as much use as possible of vegetative characters, geography, and capsule characters; capsules are generally available for longer during the year than flowers, and even when plants are in flower, last years capsules can often be found.

FAMILY INDEX

FAMILY CODE: ERICAC
FAMILY SCIENTIFIC: Ericaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Heath Family
FAMILY SUMMARY: A family of about 107-124 genera and 3400-4100 species, primarily shrubs, small trees, and subshrubs, nearly cosmopolitan. The Ericaceae is very important in our area, which is one of the north temperate centers of diversity for the Ericaceae, with a great diversity of genera and species, many of them rather narrowly endemic. Along with Quercus and Pinus, various members of this family are dominant in much of our landscape.
