Abstract

The present study focuses on the taxonomy of the subfamily Polygonoideae (Polygonaceae). This subfamily has a world-wide distribution and is an important component of many countries? floras. In this study we present the most comprehensive sampling available to date, including data from three chloroplast genes (matK, ndhF, and rbcL) for 85 species in the Polygonaceae (53 from Polygonoideae). Based on our results, we propose a new taxonomic classification for Polygonoideae that includes five well-supported tribes: Calligoneae, Fagopyreae, Persicarieae, Polygoneae, and Rumiceae. Overall, the results from molecular data represent significant progress in understanding the evolutionary relationships of major groups within the family. This classification also provides an assessment of diagnostic morphological characters for the tribes. The present work will continue to promote reevaluation of morphological characters within this diverse group, especially synapomorphies for Polygonoideae, and for tribes with a particularly complex history such as Fagopyreae, Persicarieae, and Polygoneae. A new combination, Fagopyrum tibeticum is proposed
