Solenopsis bacchettae (Campanulaceae, Lobelioideae), a new species from Sardinia.

A new species of Solenopsis (Campanulaceae), S. bacchettae from Sardinia (Italy) is described and illustrated. Previously, it was misidentified as S. bivonae, due to its habit and corolla shape, but several relevant morphological features allow to distinguish it from the latter. Its morphology, seed coat and pollen micromorphology, ecology, distribution, conservation status and taxonomic relationships are presented. [ABSTRACT FROM AUTHOR]
