Resumen:
The papilionoid genus Stylosanthes Sw. includes about 50 spp. distributed world wide in thetropics, approximately half of them grow in South America.The present study focuses on South AmericanStylosanthes. Based on examinations of herbarium specimens, as well as field observations, a total of 25taxa (23 spp. and 2 varieties) are here described and identified with a key. Most of the species have beenfound to be more widely distributed than expected from the previous taxonomic literature, and the genusappears to be mainly concentrated in Brazil and Paraguay. Stylosanthes leiocarpa Vogel is new to theflora of Argentina and the presence of S. nervosa J. F. Macbr. is confirmed in Argentina. The nomenclatureof S. guianensis (Aubl.) Sw. is analyzed. Clarifications are made about nine recently described Brazilianspecies. The names S. hispida Rich. and S. longiseta Micheli are resurrected. Lectotypes or neotypes foreight species and 18 new synonyms are proposed.
