SENTIES, Abel et al. Palisada perforata (Rhodomelaceae, Ceramiales) from the Mexican Caribbean. Rev. Mex. Biodiv. [online]. 2009, vol.80, n.1, pp.7-12. ISSN 2007-8706.

Palisada perforata was originally described from Tenerife (Canary Islands, Spain). This species has a wide distribution in tropical and subtropical zones of the Eastern Atlantic Ocean, but in the Western Atlantic there is only a doubtful record for Venezuela and Brazil. This species presents all typical features of the genus Palisada, being characterized by turf-like growth, the presence of arcuate and decumbent branches with erect branches disposed unilaterally. In the present paper we provide a detailed description of the vegetative and tetrasporangial structures. The geographical distribution of P. perforata in the Western Atlantic ocean was amplified with a new record in the Mexican Caribbean.
