Resumo

Fridericia is a conspicuous genus of neotropical lianas, with 60 species distributed among seven lineages that are broadly distributed through the neotropics in both dry and wet environments. As part of ongoing taxonomic studies of the genus, we provide taxonomic revisions of two clades: (1) the ``Acrodromous venation{''} Glade and (2) the ``Piriadacus{''} Glade. The former is characterized by 1- or 2-foliolate leaves with acrodromous venation, tubular calyces and coriaceous fruits with slightly raised edges. The latter is recognized by the red, pink-reddish or orange, tubular corolla and exserted or sub-exserted anthers. We recognize two species in each lineage and provide identification keys, morphological descriptions, illustrations, distribution maps and comments on the distribution, phenology, conservation status and taxonomy. We propose the lectotypification of 13 names: Arrabidaea brachypoda var. acuminate, A. brachypoda var. attenuata, A. brachypoda var. firma, A. brachypoda var. induta, A. brachypoda var. rigida, A. platyphylla var. Iasiorrhachis, A. platyphylla var. puberula, Bignonia brachypoda var. firmula, B. erubescens var. breviflora, B. erubescens var. subtruncata, B. regnelliana, Cuspidaria erubescens var. glabrescens and Petastoma simplicifolium. We further correct the typification of B. erubescens var. breviflora and B. erubescens var. subtruncata and propose two new synonyms for F. platyphylla (i.e. A. celastroides and B. violacea). (AU)
