Dorr, L. J. Flora of Guaramacal (Venezuela): Monocotyledons. Smithsonian Contributions to Botany, number 100, xiv + 289 pages, 26 figures, 316 maps, 2014.—The present volume is a taxonomic study of the monocotyledons that occur in Guaramacal National Park (officially El Parque Nacional “General Cruz Carillo en Guaramacal”), which protects the Ramal de Guaramacal, an outlier of the more extensive Cordillera de Merida in the Venezuelan Andes. The park covers 215 km2 in Trujillo and Portuguesa states and includes forest and paramo found between 1,600 and 3,100 m elevation. In all, 25 families, 135 genera, and 315 species (316 taxa) are treated; the greatest species diversity occurs in Orchidaceae (147 species), Poaceae (57 species), and Cyperaceae (28 species). Twenty species are currently known only from Guaramacal and might be endemic. Four new combinations are made: Cyperus hortensis (Salzm. ex Steud.) Dorr, Acronia archidiaconi (Ames) Carnevali & G. A. Romero, Crocodeilanthe gelida (Lindl.) Carnevali & I. Ramirez, and Fernandezia schultesii (L. O. Williams) Carnevali & Dorr.
