Homollea is characterized by its woody habit; well developed stipules that are interpetiolar to shortly united around the stem and triangular to lanceolate; petiolate leaves that are generally glabrous and often shiny and rather thick-textured; terminal and/or pseudoaxillary (i.e., lateral, borne in only one axil of a node), shortly cymose, mostly unbranched, pedunculate inflorescences with few to several bisexual, homostylous flowers; 5 well developed, narrow calyx lobes; a rather well developed, salverform to funnelform corolla with the 5 lobes contorted in bud; the ovary ridged and 2-locular, with 3-4 ovules in each locule; and berry-like fruits with the seeds reniform, somewhat flattened, and with entire endosperm. The inflorescences were considered pedunculate by Arènes (1960) and De Block (2003), but the flowers are typically subtended by a pair of small ovate leaves or large foliaceous bracts and a casual observer could consider the inflorescences sessile on elongated flexuous stems with a pair of somewhat reduced leaves at the apex.

De Block (2003) noted that this genus is closely related to Paracephaelis and Homoliella, although the species of Homollea do not have a very similar general aspect to the species of those genera. Paracephaelis and Homoliella both have generally branched inflorescences, shorter triangular calyx lobes, shorter corollas, and generally also pubescent leaves.
