The type, and other specimens from northern Venezuela, have relatively broad and often cuneate-obovate leaves up to 3-4 cm wide, and the pubescence of the inflorescence is usually (but not always) more abundant than in other varieties. The known altitudinal range of M . guianensis var cuneata is from about 900 to 2500 m above sea level, whereas the other varieties are mostly found below 1000 m. V E N E ZUELA.

Apparently all the rest of the local populations of this species in northeastern South America may be referred to the foUowing, the nomenclaturally typical variety, which ranges chiefly in the lowlands from northern Venezuela and Trinidad through the Guianas to Para and probably beyond, and inland in the Orinoco and Amazon basins.
