Spirostachyae, Cyperaceae) JF - Anales del Jardín Botánico de Madrid JA - An. Jard. Bot. Madr. VL - 68 IS - 2 SE - Articles DO - 10.3989/ajbm.2256 UR - https://rjb.revistas.csic.es/index.php/rjb/article/view/368 SP - 225-247 AB - The tropical African monophyletic group of <i>Carex</i> subsect. <i>Elatae</i> (sect. <i>Spirostachyae</i>) is distributed in continental tropical Africa, Madagascar, the Mascarene archipelago, and Bioko Island (32 km off the coast of West Africa, in the Gulf of Guinea). The first monographic treatment of this <i>Carex</i> group, as well as of the tribe Cariceae, was published by Kükenthal (as sect. <i>Elatae</i> Kük.). Recently, the first molecular (nrDNA, cpDNA) phylogeny of <i>Carex</i> sect. <i>Elatae</i> has been published, which also included the species of sect. <i>Spirostachyae</i>. In the resulting consensus trees, most species of sect. <i>Elatae</i> were embedded within core <i>Spirostachyae</i> and so this section was joined with sect. <i>Spirostachyae</i> as subsect. <i>Elatae</i>. Within subsect. <i>Elatae</i>, several groups were described, one of which was termed the “tropical African group”. Here we present a taxonomic revision of this group, based on more than 280 vouchers from 29 herbaria as well as in field trips in Tropical Africa. In the revision, we recognise 12 species (16 taxa) within the tropical African group, and so have somewhat modified our previous view, in which 10 species, 12 taxa were listed. One new species from Tanzania is included in this treatment, <i>C. uluguruensis</i> Luceño & M. Escudero. Several combinations are made, <i>C. cyrtosaccus</i> is treated as a synonym of <i>C. vallis-rosetto</i> and, finally, the binomial <i>C. greenwayi</i> has been recognised. ER -
