A floristic study for Canada La Chacona-Juan Crispin, Chiapas is given. 642 species and 31 infraspecies classified in 107 families and 412 genera were collected in the municipalities San Fernando, Tuxtla Gutierrez, and Berriozabal, Chiapas, Mexico. The vegetation types were tropical deciduous forest, subdeciduous tropical forest, and Quercus forest, with the highest species richness in tropical deciduous forest. Fabaceae, Asteraceae, and Euphorbiaceae were the best represented families. Tillandsia, Eugenia, and Euphorbia were the genera with the higher number of species. Herbs were the most abundant growth form (34.4%). Thirteen species were endemic to Chiapas and 19 species had a restricted distribution. Fifteen species are listed in the Norma Oficial Mexicana (NOM-059-SEMARNAT-2010), and 12 species are in the IUCN Red List. Although the level of disturbance in the area is high, the area is important due to its species richness and endemism.
