Abstract
Senna Mill. (Caesalpinioideae-Leguminosae) comprises approximately 350 species distributed in the Americas, Asia, Africa, Madagascar, Australia, and Pacific Islands. It is a taxonomically complex group and, for more than two centuries, Senna was considered part of Cassia L. The segregation of Cassia, belonging to the subtribe Cassiinae H.S. Irwin & Barneby, into three distinct genera (Cassia senso stricto, Chamaecrista [L.] Moench, and Senna) was based on floral and fruit morphologies. In this work we lectotypified ten names related to the Senna ser. Interglandulosae (Benth.) H.S. Irwin & Barneby (Cassia acuruensis Benth., C. aversiflora Herb., C. centijuga Wawra, C. holwayana Rose, C. huancabambae Harms, C. lindleyana Gardner, C. mutissiana Kunth, C. selloi G. Don, C. semifalcata Vell., and C. verrucosa Vogel) and designate an epitype for C. aversiflora.
