Cosmarium bromelicola sp. nov. (Desmidiaceae, Zygnematophyceae), uma nova espécie de desmídia do nordeste do Brazil

Abstract

Cosmarium bromelicola sp. nov. is a new desmid species described from samplings carried out in bromeliad tanks (phytotelmata) from an area of rocky outcrops at Serra da Jiboia, Bahia State, Northeast Brazil. Presence of subtrapeziform cells with a deep depression at the apical region and twisted X-shaped cell in side view are the diagnostic features for the species. Relationships with the morphologically closest taxa are discussed.
