RANUNCULACEAE. Two recent determinations in TROPICOS by MO curator Fred R. Barrie, the author of a draft treatment of this family for Flora mesoamericana, confirm the presence in Costa Rica of Clematis populifolia Turcz., an otherwise largely South American sp. The possible occurrence of said sp. in Tiquicia was discussed under the genus heading in the Manual Ranunculaceae account by Francisco Morales (UBT), but formal inclusion was withheld, as Chico had not seen any of the critical material. One of the specimens recently determined as C. populifolia by Fred is Utley & Utley 4194, mentioned in the Manual in the discussion of Clematis acapulcensis Hook. & Arn.

RUBIACEAE. Recent communication from Manual Rubiaceae coordinator Charlotte M. Taylor (MO) indicates the presence in Costa Rica of Manettia coccinea (Aubl.) Willd., a weedy, red-flowered vine now known to range from southeastern Nicaragua to Bolivia, Venezuela, and the Guianas. The two Costa Rican specimens so determined by Charlotte (both flowering in October) were collected at 200–300 m elevation on the Pacific slope, in Parque Nacional Carara and the northern Cordillera de Talamanca. Each had been previously identified as Manettia reclinata L., from which M. coccinea differs (according to information provided by Charlotte) by its corollas in bud markedly clavate (vs. tubular and slender), and at anthesis with the tube 3–4 mm in diameter (at the widest point) and funnelform (vs. 1–2 mm in diameter and cylindrical) and the lobes 5–12 mm long and broadly ovate (vs. 4–6 mm long and narrowly triangular). A quick perusal of material at CR (Santo Domingo branch) would seem to suggest that, by those characters, most Costa Rican material belongs in Manettia coccinea.
