Two new South American species of Solanum section Crinitum (Solanaceae)

Two new species of Solanum section Crinitum are described here. Solanum falciforme Farruggia, sp. nov., closely resembles Solanum crinitum and Solanum lycocarpum, but differs by the presence of falcate trichomes on the young growth. It is endemic to the cerrado and adjacent woodlands of Distrito Federal, Bahia, Goiás and Minas Gerais, Brazil. The other species, Solanum pseudosycophanta Farruggia, sp.nov., has close affinities to Solanum sycophanta butdiffers from the latter in having prominent long-stalked stellate hairs along the stem, calyx, petiole and the adaxial surface of the leaf, in contrast to Solanum sycophanta which is glabrous or pubescent with sessile to short-stalked multangulate hairs. This species is narrowly distributed in tropical montane forests of northern Peru and southern Ecuador.
