Calff’oryja, a new genus of geraniaceae endemic to the southwest of North America

Abstract

Morphological data provide evidence for the separation of £rodiwn macrophytlum Hook. & Am. in a new genus, different from either Erodium and Monsonia (Geraniaceae). Also cpDNA sequence data (trnL-F) support this view. Thus, we propose the recognition of a new monotypic genus, California Aldas., C. Navarro, P. Vargas, Ll. Suez & Aedo, to better reflect phylogenetic relationships in Geraniaceae. We provide diagnosis, illustrations, comparative analysis of distinctive characters, and a key to genera of Geraniaceae. The new combination proposed is: California macixiphylta (Hook. & Am.) Aldas., C. Navarro, P. Vargas, Ll. Sfiez & Aedo, comb. nov. [basion.: Erodium matroPhyllum Hook. $ -l: and two lectotypes are designed.
