Abstract
Lasiocroton trelawniensis (Euphorbiaceae), a critically endangered species from the Cockpit Country of Jamaica, belongs to Bernardia (Euphorbiaceae). Botanical Review Vol. 74, No., 1 2008.—A taxonomic study based on scanning electron microscopy of pollen, macro-morphology, and a molecular phylogenetic analysis of the chloroplast DNA regions trnL-F and rbcL shows that Lasiocroton trelawniensis belongs to the Neotropical genus Bernardia. The main morphological differences between Bernardia and Lasiocroton are given, and the new combination Bernardia trelawniensis is provided.
Resumen
Un estudio taxonómico basado en microscopía electrónica de barrido del polen, en macro-morfología, y en análisis filogenéticos moleculares de las regiones del ADN de los cloroplastos trnL-F y rbcL muestra que Lasiocroton trelawniensis pertenece al género neotropical Bernardia. Se dan las principales diferencias morfológicas entre Bernardia y Lasiocroton y se da así mismo la nueva combinación Bernardia trelawniensis.

Acknowledgments
We dedicate this paper to the memory of Professor Grady Webster (1927–2005), the Euphorbiaceae authority who, during his graduate studies, worked alongside George Proctor in Jamaica over fifty years ago. We would like to thank the EPA GRO-STAR Fellowship (Number MA-91630201-3 to BJ) for financial support. Andreas Oberli and Devon Paddyfoot provided invaluable help during the field studies of BJ and GP in Jamaica. We would also like to thank Angelica Cervantes for sending us her doctoral thesis on the taxonomy of Bernardia. Our thanks go out to Barbara Maloney from FCAEM of FIU for technical support for this study. This study is part of the Ph.D. Dissertation of BJ, our gratitude also goes for his graduate study committee; Maureen Donnelly, Kelsey Downum, Grenville Draper, Carl Lewis, and Jennifer Richards who critically read an early draft of this paper. We also appreciate the three anonymous reviewers who provided useful comments. This is contribution number 141 from the Tropical Biology Program of FIU.
