MENDOZA-RUIZ, Aniceto; CEJA-ROMERO, Jacqueline  and  MEJIA-MARIN, María Isabel. Lycopods and ferns of San Juan Colorado, Oaxaca, Mexico. Rev. Mex. Biodiv. [online]. 2017, vol.88, n.1, pp.49-55. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2017.01.019.

In order to carry out a checklist of the lycopods and ferns from the municipality of San Juan Colorado, an unexplored area located in the District of Jamiltepec, Oaxaca, several field trips were made from 2012 to 2014. A list of 15 families, 33 genera, and 68 species was recorded for the municipality, which increased to 81 the taxa in the District and represents 11.8% of the total reported at the state level for this group of plants. The vegetation types with higher species richness were the semi-deciduous tropical forest and the cloud forest. We registered for the first time in Oaxaca: Adiantum decoratum, Anemia intermedia, and ×Hemionanthes gryphus. Seventy nine per cent of the taxa are terrestrial. Comparison of these results with previous information available at a district and a municipal level shows the importance of local floristic studies to advance the knowledge of plant diversity of Oaxaca.
