The tree flora composition in the PNA (protected natural area) Tenancingo-Malinalco-Zumpahuacán, State of Mexico, Mexico. Polibotánica [online]. 2012, n.34, pp.51-98. ISSN 1405-2768.

The floristic study of trees was carried out in the Protected Natural Area (PNA) Tenancingo-Malinalco-Zumpahuacan. The identified specimens comprise 304 species, 165 genera and 72 families. The most representative families are Leguminosae with 58 species (Fabaceae 15, Mimosaceae 35 and Caesalpiniaceae 8), Fagaceae with 23, Burseraceae with 19 and Moraceae with 14; of wich 242 are native, 20 non native and 42 endemic. We identified six distinct types of vegetation: tropical deciduous forest, tropical subdeciduous forest, montane mesophytic forest, oak forest, pine-oak forest and gallery forest. In addition, we detailed 71 new species reports for the State of Mexico. The most species richness occurred in the tropical deciduous forest (170) and gallery forest (104).

Keywords : floristic; State of Mexico; angiosperms; gymnosperms; endemic.
