Abstract

Phylogenetic placement of Puelia and Guaduella, two broad-leaved African grass genera traditionally classified as bamboos, is inferred from analysis of ndhF, rbcL, and PHYB sequence data. Puelia and Guaduella are supported as sister genera, and the Puelia/Guaduella clade is resolved as an early diverging branch within the Poaceae and sister to the BEP + PACC clades, which include the bulk of the family. The new grass subfamily Puelioideae is described to accommodate the Puelia/Guaduella clade.
