See list of 3 genera in this family-
1a. Leaves simple, entire; fruiting panicle with long-plumose, sterile pedicels
-
1b. Leaves pinnately compound, the leaflets entire or, more commonly, toothed; fruiting panicle without long-plumose sterile pedicels (though the fertile pedicels may be short-pubescent)
-
2a. Drupes red, conspicuously pubescent; inflorescence terminal or borne laterally on the previous season’s branchlets, the flowers and fruits crowded; leaves with 7–31 leaflets or only 3 leaflets in R. aromatica; petals often pubescent on the adaxial surface
-
