Acceptance : Accepted

Note : Palicourea sect. Egenses

Project Data (Last Modified On 7/9/2018)

Notes: This species shows some clinal morphological variation from west to east across the Amazon basin (detailed by Taylor, 2018), but the forms found at the geographic extremes are not completely distinct. Plants from Lake Maracaibo region in northern Venezuela are markedly disjunct but not morphologically distinct, and are treated here as a subspecies; this region was previously connected with the Amazon basin, although long ago, and these areas have some phytogeographic connections. Palicourea egensis is smilar to Palicourea phaneroloma, Palicourea schomburgkii, Psychotria gracilenta, and Pagamea.
