This species is widespread, frequent in secondary vegetation (but also found in primary vegetation), and morphologically variable. It is part of a complex of species or forms in the Amazon Basin of South America that also includes Palicourea grandifolia, if that species is distinct. Palicourea guianensis is distylous throughout most of its South American range, but appears to be monomorphic (or homostylous) in the Antilles and perhaps also in Central America and coastal Colombia west of the Andes. Palicourea guianensis is also notable for its variation in number of ovary locules and styles, with 2 locules, 2 styles, and 2 pyrenes in the plants of most of its range but with some plants having 3 and some having 4 or even 4 in northeastern South America; these plants have been separated at the variety level by some authors, but appear to be sympatric with 2-locular plants and similar variation is found in other species in that region.



Wet forests, 0-1500 m, Mexico (Veracruz) to Bolivia and southeastern Brazil and throughout the Antilles.
