%X Se realiz¨® la descripci¨®n morfol¨®gica de los 11 g¨¦neros de bamb¨²es le osos nativos y ex¨®ticos asilvestrados presentes en Venezuela. Se presentan claves dicot¨®micas para identificar tanto espec¨ªmenes vegetativos como f¨¦rtiles, lista de las especies reportadas para cada g¨¦nero, con informaci¨®n sobre distribuci¨®n y ecolog¨ªa. La lista fue elaborada a partir de las colecciones de Bambusoideae de los herbarios ISC, MER, MERC y VEN, y complementada con informaci¨®n de bases de datos, publicaciones peri¨®dicas, fl¨®rulas y cat¨¢logos. Se concluye que Venezuela tiene una diversidad importante de bamb¨²es le osos, con 67 especies nativas, de las cuales 20 son end¨¦micas (29,9%). Myriocladus, aulonemia, Merostachys y Rhipidocladum constituyen los g¨¦neros con mayor endemismo. chusquea y Myriocladus representan los g¨¦neros m¨¢s diversos, con 20 y 12 especies, respectivamente. Los g¨¦neros con distribuci¨®n m¨¢s amplia en el pa¨ªs son arthrostylidium, chusquea, Guadua y Rhipidocladum; los g¨¦neros atractantha, Merostachys y Myriocladus presentan distribuci¨®n restringida, limitada al estado Amazonas para el primero, y Amazonas y Bol¨ªvar para los dos ¨²ltimos. A morphological description of the 11 genera of woody bamboos reported for Venezuela, including both native and naturalized exotic species was done. Dichotomous keys designed to identify vegetative as well as fertile specimens are proposed. An updated list of the species reported for each genus is also included, with information related to their distribution and ecology. The checklist was elaborated based on the Bambusoideae collections of the herbaria ISC, MER, MERC and VEN, complemented with information obtained from online available taxonomic databases, journal publications, local floras and catalogues. We conclude that Venezuela is noteworthy for its diversity in woody bamboos, with a total of 67 species, of which 20 (29.9%) are endemic. Myriocladus, aulonemia, Merostachys and Rhipidocladum represent the genera with the largest endemism. chusquea and Myriocladus stand out as the most diverse genera, with 20 and 12 species, respectively. arthrostylidium, chusquea, Guadua and Rhipidocladum represent the genera with broadest distribution range in the country. The distribution of atractantha, Merostachys and Myriocladus is restricted to Amazonas State for the first genus, and Amazonas and Bol¨ªvar, for the last two genera.
