ARAQUE, Osmary Z; LEON H, Williams J  and  HERNANDEZ P, Clemente. Wood anatomy of lianas of the bignoniaceae family in caparo forest Reserve (Barinas state, Venezuela). Acta Bot. Venez. [online]. 2007, vol.30, n.1, pp.191-215. ISSN 0084-5906.

The wood anatomy study of eleven lianas species from Bignoniaceae family reported in the Caparo Forest Reserve (Barinas state,Venezuela) is presented: Anemopaegma chrysoleucum, Arrabidaea candicans, A. verrucosa, Ceratophytum tetragonolobum, Cydista aequinoctialis, Macfadyena uncata, M. unguis-cati, Paragonia pyramidata, Pithecoctenium crucigerum, Phryganocydia corymbosa and Xylophragma seemannianum. The species were included in two groups: species with two-sized rays and species without two-sized rays. All the species have two-sized pores, simple perforation plates, alternate intervessels pits, circular to oval, ray-vessels pits similar to intervessel pits in size and shape, paratraqueal vasicentric parenchyma and cambial variants (anomalous structure). A dichotomous key for identification is presented
