Fabaceae (=Leguminosae )

subdivided into Faboideae (= Papilionoideae), Mimosoideae, Caesalpinioideae

these were formerly families: Papilionaceae, Mimosaceae, Caesalpinaceae

of these, Caesalpinioideae is the most problematic genetically (perhaps paraphyletic)


characters: always have stipules, leaves usually alternate and compound, leaflet margin normally entire, flowers with 5 petals; pods usually dehiscent (open along a seam)

Fabaceae--Caesalpinioideae


(=Caesalpinaceae)

tribes: Cassieae, Caesalpinieae, Deteriae; the Cercideae are thought to be sisters to the others

characters: flowers are usually zygomorphic but highly variable, petals are normally the showy parts
