With the exception of A. americana, AboVboda pulchella is the most widely distributed species of the genus. To the north of the Amazon River, the population is remarkably uniform. To the south of the river, however, the species is quite variable, as is attested by the several names proposed for it. Smith and Downs have recently concluded that the entire population must come under one name. I am in agreement with this position. However, I do feel that there are probably represented several strong infraspecifie geographic and morphologic races, one of which would be the long-leafed, large-spiked specimens from the vicinity of Cuyaba, Matto Grosso, formerly described by Malme as .4. lonc/ifolia. Such luxuriant individuals as these (i.e. specimens referable to A. longifolia) form a very close connecting link with A. poarchon Seub.
