NEW TAXA OF AMAZONIAN
CHRYSOBALANACEAE
Ghillean T. Prance (*)
SUMMARY
t o m e n t o s o ; s t i p u l i s 2-2.5 c m Ion-
Five new taxa of Amazonian Chrysobalanaceae are described based on recently collected material: Couepia cidiana Pran ce, Hirtella radamii Prance, Licania heteromorpha Benth. var. revoluta Prance, Licania miltonii Prance, and Licania tocantina Prance. The continued collection of many undescribed taxa indicates that there is still much to be done in the basic botanical inventory of Amazonia.

Resumo Cinco taxa de Chrysobalanaceae da Amazônia são descritos como novos: Couepia cidiana Prance, Hirtella radamü Prance, Licania heteromorpha Benth. var. revoluta Prance, Licania miitonii Prance e Licania tocantina Prance. São baseados em material recentemente coletado na terra firme da Amazônia Brasileira. A continuação da coleção de tantas espé cies novas mostra que ainda falta muito para se completar o inventário básico da flora amazônica. Este trabalho é uma continuação da atualização da monografia de Chrysobalanaceae publicado em Flora Neotrópica em 1972.
