The Puelioideae, a new subfamily of Poaceae

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