Intraspecific variation of insertion/length of stamens in homostylous flowers of a new species and three other species of borreria : an unusual case in rubiaceae

Four species of Borreria subsection Latifoliae (Rubiaceae) present intrafloral variations in the insertion/length of stamens in homostylous flowers. Borreria heteranthera is described and illustrated as new species from the state of Pará, Brazil. The emended descriptions of Borreria hispida, B. se...
