This dataset contains the digitized treatments in Plazi based on the original journal article Ruiters, Ashton K., Tilney, Patricia M., Wyk, Ben-Erik Van, Magee, Anthony R. (2016): Taxonomy of the Genus Phymaspermum (Asteraceae, Anthemideae). Systematic Botany (Basel, Switzerland) 41 (2): 430-456, DOI: 10.1600/036364416X691768, URL: doi.org/10.1600/036364416x691768 Abstract — Phymaspermum, the largest and most complex genus within the subtribe Phymasperminae, is revised and 17 species are recognised, all endemic to southern Africa.

Four new species are described (P. aphyllum, P. comptonii, P. oppositifolium, and P. trifidum), five species are reduced into synonomy (P. bolusii, P. equisetoides, P. montanum, P. pubescens, and P. villosum) and P. thymelaeoides is recognized as the oldest available epithet for P. schroeteri. The species of Phymaspermum can be distinguished by a combination of habit, leaf, involucral, and fruit characters. Species relationships are assessed in a cladistic analysis of 12 anatomical and morphological characters.
