VIANA, Simone Silva; SANTOS, João Ubiratan Moreira dos  e  SIMOES, André Olmos. Taxonomic diversity of Apocynaceae at the Marajó Island, PA, Brazil. Rodriguésia [online]. 2017, vol.68, n.2, pp.623-652. ISSN 2175-7860.  http://dx.doi.org/10.1590/2175-7860201768221.

This work presents a taxonomic treatment of species of Apocynaceae occurring in Marajó Island. We analyzed materials from the herbaria IAN, INPA, MG, R, RB, SP, SPF e UEC, as well as specimens collected in three field trips made in July 2011, November 2011 and February 2012. The family is represented in the studied area by 33 species belonging to 21 genera, as follows: six genera with seven species belonging to subfamily Apocynoideae, five genera and 12 species belonging to subfamily Asclepiadoideae, and nine genera with 14 species from subfamily Rauvolfioideae. Prestonia annularis is registered for the state of Pará for the first time, while Spongiosperma grandiflorum and Macoubea guianensis are new records for the Marajó Island. Up to this work, Forsteronia paludosa was known only by the type collection. We provide identification keys, morphological descriptions, phenology and habitat information, geographical distribution, taxonomic comments and illustrations of the species. Forsteronia paludosa and Macoubea guianensis are here illustrated for the first time.

Palavras-chave : Apocynoideae; Asclepiadoideae; Rauvolfioideae; taxonomy.
