CLARK, Lynn G  e  EY, Francisca U. Genera of Venezuelan woody bamboos (Poaceae: bambusoideae: arundinarieae, bambuseae). Acta Bot. Venez. [online]. 2011, vol.34, n.1, pp.079-104. ISSN 0084-5906.

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 Bolívar, for the last two genera.
