The Manual de Plantas de Costa Rica is a concise, illustrated guide to all of the species of native, naturalized and commercially cultivated vascular plants of this Central American country, which lies between Nicaragua and Panama and is thus centered in isthmian Central America, a biogeographical funnel between South and North America, densely rich in species and geological history. The Manual is the first comprehensive Spanish-language account of the Costa Rican flora. The work is presented in a series of several volumes; Volume II, including all the gymnosperms and part of the monocots, is the first to appear.
Volumen II. Gimnospermas y MonocotiledÃ³neas (Agavaceae Musaceae)
Nearly one half of the species in this volume are distributed among three large, economically and ornamentally important families, the Araceae (Philodendron
, etc.) with 248 species, the Arecaceae (the palms) with 109 species, and the Bromeliaceae (pineapple, etc.) with 195 species. A total of 1125 species of monocots in 35 families are presented. Gymnosperms, of low diversity in the tropics, with only five families and 13 species in Costa Rica that fit the Manual s general criteria of native, naturalized, or commercially cultivated, are fully treated. Besides brief formal descriptions and informal notes about each of a total of 40 families, 190 genera, and 1136 species of seed plants, this identification manual contains keys to all the gymnosperm and monocot families treated in the series, as well as to the genera and species included within this volume. A total of 218 original line drawings and 40 black-and-white photographs illustrate the treatments.
