Abstract

The reinstatement of the genus Xiphotheca Eckl. & Zeyh. (Fabaceae, tribe Liparieae) is proposed. A study of the morphology and alkaloids of the genus Priestleya DC. has shown remarkable differences between its two sections, P. sect. Priestleya and sect. Aneisothea DC. (= Xiphotheca). The latter differs in its geminate flowers, the non-intrusive calyx, the obtuse and pocketed keel petals, the uniform anthers, the shortly petiolate and pinnately veined leaves and the unique combination of alkaloids. A brief synopsis of the genus, including nomenclature, synonymy and typification, is presented.
