Dichotomous Key

back to "conifer or broadleaf?" Are the leaves compound? Are the leaves simple?
Although broadleaved trees, or broadleaves, from all over the world can grow in Oregon, only about 35 species are native here-- and about a dozen commonly grow as shrubs rather than as trees. Based on the structure of their flower and fruit, these species can be grouped into 17 genera.
