REYES, ORLANDO J.  e  ACOSTA CANTILLO, FÉLIX. New phytocenoses in semideciduous forests of extreme east of Cuba. Caldasia [online]. 2011, vol.33, n.2, pp.507-518. ISSN 0366-5232.

The semideciduous forests of the extreme east Cuba were studied in Sabana and Maisí areas, Guantanamo province, over karstic formations, whose rainfalls fluctuate between 600 to 1000 mm each year, with a marked dry period. By using the Zurich-Montpellier school methodology, two associations new for science are described. Calophyllo antillani-Ocoteetum coriaceae in ferralitic red and fertile soils (mesophil semideciduous forest) and Thouinio patentinervis-Burseretum simarubae (microphil semideciduous forest) on "lapiez", with a defined root mats where this ecosystem’s nutrient cycle is produced.
