Botanical Research and Applications

The Dichorisandra acaulis group has its circumscription broadened to include two additional species, viz. D. oxypetala and the herein newly described D. forzzae . Dichorisandra oxypetala has previously not been included in this morphological group due to its deviant vegetative morphology. However, its reproductive morphology is congruent with the D. acaulis group and, thus, it is here included as a member of the later. Dichorisandra forzzae is here described to accommodate the specimens with anthers dehiscent through one apical pore, erroneously identified as D. acaulis in the state of Espírito Santo, Brazil. We provide illustrations, taxonomic comments and an updated identification key for the species of the D. acaulis morphological group. Furthermore, a table of comparison among the morphologically similar species of the Dichorisandra acaulis group is presented.
