	 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.
