Palicourea Aubl. includes in its traditional sense about 250 species of shrubs and small trees distributed widely in the New World tropics. Palicourea plants are typically found in the understory and subcanopy of moist to wet tropical forests, from low to high elevations. Palicourea flowers have well developed tubes and are odorless, mostly brightly colored, and assumed to be pollinated by hummingbirds, and its fleshy blue or purple-black fruits are dispersed by birds. Nearly all Palicourea species are distylous; this appears to be the ancestral condition for the genus, and it seems to have been lost in at least a few species on Caribbean islands (Taylor, 1993).

Palicourea has not been surveyed as a whole since Schumann's review of the Rubiaceae (Schumann, 1891), although several regional treatments are available (Steyermark 1972, 1974; Bacigalupo 1952; Burger & Taylor 1993; Jung-Mendaçolli et al 2007; Taylor 1989, 1993, 2000, Taylor et al. 2007) and monographic work is in progress (Taylor, 1997). Palicourea is notable for the large number of apparently closely related species it includes, and for the frequent sympatric occurrence of several different species of Palicourea in a particular site.

Palicourea is closely related to Psychotria subg. Heteropsychotria Steyerm., and in fact both morphological (Taylor, 1996) and molecular studies (Nepokroeff et al., 1999; Andersson, 2001; Andersson & Rova, 1999) show that Palicourea is polyphyletic and derived from within Subg. Heteropsychotria. These genera have been separated by their flower morphology: Palicourea has the usually colored flowers separated on developed pedicles, corollas with well developed tubes, abundant nectar, and other adaptations for hummingbird pollination, while Subg. Heteropsychotria generally has small white flowers that are pollinated by insects. Thus the reproductive characters that have been used to circumscribe Palicourea are plastic. Much work remains to be done in understanding species identities and relationships before these genera can be united in a meaningful fashion. The whole group takes the name Palicourea, and also includes species formerly called Cephaelis.
