GARCIA FRANCO, José G. et al. Floristic inventory of a cloud forest in the central portion of Veracruz, Mexico. Bol. Soc. Bot. Méx [online]. 2008, n.83, pp.37-52. ISSN 0366-2128.

In the central area of Veracruz a few remnants of cloud forest (CF) have not been explored previously. We studied the floristic composition and some structural features of one of these remnants of CF in La Cortadura. Sampling of woody plants, herbs and vascular epiphytic species was made in three river basins (plots of 1000 m² each). The sampled areas showed dense canopy cover, some emergent tree species, and similar life form proportions. We recorded 258 species (150 genera, 82 families), however the forest is heterogeneous. Even though the number of species found in each river basin was nearly similar (144-163), they only shared 55 species (34-38%). The CF at La Cortadura is well preserved and contains 58 and 31 % of the preferred or exclusive families for this vegetation type. In addition, some new distribution records and a new species were recorded for the area.
