A preliminary identification by INBio's Francisco Morales suggests the occurrence of Begonia brevicyma C. DC. at Estación Pittier, at ca. 1680 m elevation on the Pacific slope of the Cordillera de Talamanca in the Coto Brus region. The collection, by parataxonomist Annia Picado, extends the range of the sp. northward from the nearest station in Prov. Chiriquí, Panama. BURSERACEAE. In our inaugural issue, we reported the first Mesoamerican collection of the genus Dacryodes, from mid-elevation forests on the Atlantic slope of the Cordillera de Talamanca [see The Cutting Edge 1(1): 9, Jan. 1994]. The same, still-unidentified sp. can now be reported from the Pacific slope of the same range, near Estación Pittier, in the Coto Brus region. A good, fruiting collection was prepared by Manual co-PI Nelson Zamora, together with parataxonomists Reinaldo Aguilar and Marcos Moraga. The mystery Dacryodes was one of the most common trees in the area, as was also the case at the Atlantic-slope station. Flowers, critical to positive identification, have yet to be collected. FABACEAE/MIMOSOIDEAE. Parataxonomist and park guard Ulises Chavarría is responsible for the first Costa Rican collection of Mimosa asperata L., ranging southward from Mexico to Parque Nacional Palo Verde reserve in Prov. Guanacaste (where Ulises found it), and with a disjunct population on Cuba. FABACEAE/PAPILIONOIDEAE. A collection from 1750 m elevation in the upper Río Reventazón basin, made by Universidad Nacional Autónoma de Heredia botanist Alexander ('Popeye') Rodríguez, appears to represent Crotalaria filifolia Rose. This sp. has been regarded as a Mexican endemic, ranging southward only to Oaxaca. JUGLANDACEAE. Francisco Morales reports the first Costa Rican records of the otherwise Chiapan Alfaroa mexicana D. E. Stone, from several sites on Fila Bustamante, in the Acosta region south of San José.
