Abstract

I aim: (1) to distinguish by key the species of Dyssodia in Texas; (2) to map their Texas distribution as indicated by herbarium specimens; and (3) briefly, to indicate and discuss their relationships and nomenclature. Upwards of 2500 herbarium specimens have been examined. Many of these were not collected in Texas; this over-all survey threw much taxonomic light on, and indeed was prerequisite to an adequate understanding of, the Texas members of the group.
