Ericaceae A.L. de Jussieu. Heath Family.

Key to Ericaceae

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.

Main Key, for use with flowering or fruiting material.
