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

Abstract

Two new species of Solanum section Crinitum are described here. Solanum falciforme Farruggia, sp. nov., closely resembles S. crinitum and S. 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. Te other species, Solanum pseudosycophanta Farruggia, sp.nov., has close affinities to S. sycophanta but differs 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 S. sycophanta which is glabrous or pubescent with sessile to short-stalked multangulate hairs. Tis species is narrowly distributed in tropical montane forests of northern Peru and southern Ecuador.
