Manual de Plantas de Costa Rica 



Pseudocentrum hojfmannii, p. 61; Pterichis haben- 

 arioides, p. 63; Sarcoglottis hunteriana, p. 45; y 

 Trevoria zahlbruckneriana, p. 245. Estos nombres 

 son los que se usan en el Manual y el niimero a la par 

 corresponde a la pagina de la pintura fuente, en el 

 libro del Dr. Rodriguez. Estamos muy agradecidos a 

 la Sra. Hortensia Sevilla de Rodriguez, titular de los 

 derechos de autor de este libro, por autorizar la eje- 

 cucion y publication de estas ilustraciones. 



Las ilustraciones de gramineas, menos unas cuan- 

 tas, son las mismas usadas en la Flora costaricensis 

 (Pohl, 1980); la Iowa State University nos presto la 

 mayoria de las ilustraciones originales de ese trabajo. 

 Agradecemos a William Burger por su ayuda en este 

 respeto, y especialmente a Lynn G. Clark por ayu- 

 darnos conseguir el permiso y por traernos las ilus- 

 traciones a Costa Rica. A Judy Appenzeller LaMotte 

 (firma, JEA), autor principal de esas ilustraciones de 

 gramineas, por su trabajo fino. Todas las otras ilustra- 

 ciones en este volumen fueron ejecutadas por Silvia 

 Troyo, quien tambien estuvo a cargo del escaneo de 

 todas las ilustraciones. Varios trabajos — especifica- 

 mente The families of the monocotyledons (Dahlgren 

 et al, 1985), Flora ofBarro Colorado Island (Croat, 

 1978), Flora of Guatemala (Standley & Steyermark, 

 1958-1975), Flora of Panama (Woodson & Schery, 

 1943-1981) y la serie Flora Neotropica Mono- 

 graphs — fueron de gran ayuda como fuentes inter- 

 pretativas para la elaboration de las ilustraciones; sin 

 embargo, cualquier semejanza entre estas y las ilus- 

 traciones del Manual seria mera coincidencia debido 

 a la naturaleza del material. Todas las fotos son de 

 Barry Hammel, menos las de orquideas en las lami- 

 nas en color para las cuales extendemos las gracias 

 a Kerry Dressier. Varias de esas fotos de orquideas 

 se parecen a las que uso Roberto Dressier (1993) en 

 su Guide to the orchids of Costa Rica and Panama. 

 Damos gracias a Cornell University Press por ex- 

 tendemos el permiso de reproducir aquellas fotos. 

 Marco V. Castro, geografo del INBio, elaboro los 

 cuatro mapas que ilustran las partes internas de la 

 portada del Manual 



Este Manual tambien es el resultado de una serie 

 de tres becas (BSR-8700068, BSR-9006449, DEB- 

 9300814) otorgadas por la National Science Founda- 

 tion. Los fondos concedidos a Michael Grayum a 

 traves de la National Geographic Society (NGS33 17- 

 86 y 4682-91) permitieron una serie de exploraciones 

 importantes de la vertiente del Caribe de la Cordillera 

 de Talamanca. Aunque culminaron poco antes del 

 lanzamiento del proyecto del Manual, expediciones 



numbers correspond to the paintings in Dr. Rodri- 

 guez's book. We are very grateful to Sra. Hortensia 

 Sevilla de Rodriguez, who retains the rights of au- 

 thorship to that book, for having kindly authorized 

 this publication of said illustrations. 



The majority of the grass illustrations are the same 

 as those used in Flora costaricensis (Pohl, 1980); 

 most of the originals from that work were loaned to us, 

 generously, by Iowa State University. We are grateful 

 to William Burger for his guidance in this regard, and 

 especially thank Lynn G. Clark for helping us get 

 permission and for bringing the illustrations to us 

 in Costa Rica. We are, of course, indebted to and 

 thank Judy Appenzeller LaMotte (signature, JEA), 

 principal author of those illustrations, for her fine 

 work. All of the other illustrations in this volume 

 were executed by Silvia Troyo, who was also in 

 charge of the scanning of all illustrations. Published 

 works, specifically The families of the monocotyle- 

 dons (Dahlgren et al., 1985), the Flora ofBarro Col- 

 orado Island (Croat, 1978), the Flora of Guatemala 

 (Standley & Steyermark, 1958-1975), the Flora of 

 Panama (Woodson & Schery, 1943-1981), and the 

 Flora Neotropica Monographs series, were often of 

 great help as interpretive sources in the construction 

 of our original illustrations; any similarity between 

 their and our final illustrations is, however, coinci- 

 dental and a result of the nature of the material. All 

 photographs are by Barry Hammel, except for the 

 Orchidaceae in the color insert, which are by Kerry 

 Dressier. Several of the orchid photos resemble those 

 that appeared in Robert Dressler's (1993) Guide to 

 the orchids of Costa Rica and Panama. We thank 

 Cornell University Press for granting permission to 

 reprint those photos. Marco V. Castro, INBio geogra- 

 pher, elaborated the four maps found on the endpa- 

 pers of the Manual. 



This publication is the direct product of a series of 

 three major grants (BSR-8700068, BSR-9006449, 

 DEB-93008 14) awarded by the National Science Foun- 

 dation. Funds granted to Michael Grayum through 

 the National Geographic Society (NGS 3317-86 and 

 4682-91) allowed a series of important explorations 

 of the Caribbean slope of the Cordillera de Tala- 

 manca. Even though they came just before the ini- 

 tiation of the Manual project, NGS grants to Gerrit 

 Davidse (see Davidse et al., 1994) and W. D. Stevens 

 (see Stevens et al., 2001), from which Costa Rican 

 floristics profited immensely, also receive our appre- 

 ciation. We are greatly indebted to the recently estab- 

 lished Taylor Fund for Environmental Research, and
