Resumen:
Background and aims The identity of Diodia assurgens K.Schum. is unclear and the taxon has never
been studied in detail since its description. In the present paper we aim to clarify its status and taxonomic
position.
Methods Normal practices of herbarium taxonomy have been applied to study all herbarium material
available. Pollen of Diodia assurgens and Diodia s. str. species was studied using the acetolysis method.
Key results The comparative morphological study clearly shows that Diodia assurgens K.Schum
belongs to the genus Spermacoce s. str. and that it should be excluded from Diodia s. str. The new name
Spermacoce spiralis Bacigalupo & E.L.Cabral is proposed and a lectotype is designated. The species is
also described and illustrated. The palynological characters of Spermacoce spiralis agree well with those
observed in other species of Spermacoce s. str.
