Cyatheals or tree ferns with fossil record date back to the Jurassic period. In the present flora, they are a vital part of the biodiversity of the ecosystem of cloud forest and are endangered. The order includes eight genera and 750 species that belong to the genus Cyathea. It is tropical and subtropical and extend into temperate regions of New Zealand and South America. They are abundant as understory species in forests. The trunks are branched and their height ranges from 1 to 20 m. The stipes of ciateales are herbaceous, rhizomes have a central protostele in the older parts, which goes in a very varied way to a lattice with a sifonostela or polistela character, central xylem, peripheral phloem in the effort sometimes thick (with caulogenous rigid roots). The mensuration of Cyatheaceae Cuetzalan restored in situ was determined. The weighted stipe growth varies between 30 and 90 cm per year, depending on soil type, shade and competition of tree species, the Ø-(X) 15-23 cm, frond number 24 by stipe. The maturation of the "stem" is useful for its use starting from the 10th year. The discussion has always been geared toward its commercial use. Harnessing maquique revealed sustainable results.
