The extremities of the styles are swollen out in a flattened blade or in the form of a reversed foot, and covered internally with stigmatic papillae. The dorsal wing surmounting the cocci of the fruit is rather thick and short. The inflorescence resembles that of Brachypterys. The same may be said of Stigmaphyllon, climbing shrubs from tropical America, with leaves usually opposite. But, of the Kg. 440. Flower, with , , , .

Four of those which are alternipetalous have an anther, abortive, deformed, or even totally absent. The fruit is a samara with dorsal wing longer than in Brachypterys. Heteropterys^ shrubs, sometimes climbing, of tropical America and Africa, have the closest affinities with Stigmaphyllon and Brachypterys; they possess the carpels with developed dorsal wing of the former, and the styline branches with stigmatiferous apex in shape of a foot of the latter; they have moreover the flower of both with a calyx having eight glands or thereabouts. But the inflorescence is in simple or ramified clusters, with articulate pedicels accompanied by two lateral bractlets; a character of small value in itself, but which may serve provisionally to separate them from the two preceding genera. Henleophyton^ glabrous and tortuous shrubs from Cuba, is also closely allied. They are said to be distinguished by peltate or stipitate calycine glands, by styline branches with capitate stigma- tiferous apex, and by carpels withou
