The following taxa of Ericaceae are newly described from Panama: Cavendishia aberrans Luteyn, C. arizonensis Luteyn, C. chiriquiensis var. bullata Luteyn, C. fortunensis Luteyn, Didonica panamensis Luteyn & Wilbur, Disterigma hammelii Wilbur & Luteyn, Lateropora tubulifera Wilbur & Luteyn, Macleania megabracteata Wilbur & Luteyn and Themistoclesia revoluta Wilbur & Luteyn. Cavendishia quereme (H.B.K.) Bentham & Hooker is reported for the first time from Panama, being previously known only from Costa Rica and Colombia. Vaccinium dissimile Blake is now known from Col6n Province and the range of Vaccinium jefense Luteyn & Wilbur is extended to include Cock6 Province. Keys to the Central American representatives of the genera Disterigma, Lateropora, and Themistoclesia are provided. It may be surprising to many that, although an account of the Ericaceae of Panama was published only recently (Wilbur & Luteyn, 1978) based upon a study of all collections available in the American herbaria with significant holdings of Panamanian plants, a paper would be published so soon increasing by 15% the known ericad flora of that small county. All of these additions are based upon collections previously unavailable to us, and almost all are from collections made in only recently explored areas. It is safe to predict that many additional species await discovery in the extensive areas of Panama that are botanically either unexplored or little explored, and it is to be hoped that funds for continued exploration will be forthcoming. Obviously the botanical exploration of this biogeographically critical area is far from completed.
