Distribution and Ecology. Heliophilous, dominant in restinga and low coastal dunes of eastern Brazil , in Bahia, Rio de Janeiro, and Espírito Santo. It occurs on white sandy soils from sea level to 100m. (Mónica Moraes, Flora Neotropica, monograph 73, Allagoptera) (Mónica Moraes, Flora Neotropica, monograph 73, Allagoptera)A

Discussion

  • The variable number of stamens in Allagoptera arenaria being 10-18 is the one of the main diagnostic characters used to include the descriptions of Cocos arenaria by Gomes (1812) and A. pumila by Nees (1821) under A. arenaria. In the original description, Gomes (1812) mentioned Rio de Janeiro as the only locality for Cocos arenaria, but no information was given for his illustration; nor was the collector and the specimen on which he based his description. It could not be found in herbaria in Portugal or Brazil. Probably he worked with cultivated material. Martius (1826) described Diplothemium maritimum and D. littorale as separate species, based on two phenological states of the species A. arenaria; the first name was based on plants with flowers and the second on plants with fruits.
    Wied-Neuwied (1821) announced that Martius was going to describe A. pumila in his work on Brazilian palms. Wied-Neuwied also referred to a collection brought by Martius from Brazil, but unfortunately no herbarium contains that material; the search was done at M, B, LE, and several Brazilian herbaria.
