Polygalaceae Hoffmannsegg & Link. Milkwort Family.

Key to Polygalaceae

A family of about 29 genera and about 1200 species, trees, shrubs, woody vines, and herbs, nearly cosmopolitan, but most diverse in tropical and subtropical areas.

ID notes:The Polygalaceae has a distinctive flower structure which can be confusing. The corolla consists of 3 fused petals, partly fused into a tube, and also fused with the stamens. The lower petal is called the keel; it is usually boatlike, and also lacerate, fringed, or lobed at its tip (in most species). The calyx is 5-lobed, the lobes usually of 3 distinct sizes. The two lateral sepals are called wings; they are generally large and petaloid (colored like petals). The upper sepal is usually the next largest; the two lower sepals are usually the smallest.
