A revision of the endemic Brazilian <i>Solanumhexandrum</i> group (Leptostemonum, <i>Solanum</i>, Solanaceae).

ABSTRACT: The Leptostemonum Clade, or the 'spiny solanums', represents half of the species diversity of the large cosmopolitan genus Solanum (Solanaceae). Brazil is a centre of both species and lineage diversity in 'spiny solanums' with a number of lineages occurring mostly only there. Here, we treat the Solanumhexandrum group, a monophyletic species group that is part of the larger and unresolved Erythrotrichum clade sensu lato. The six species treated here are all robust very prickly shrubs with amongst the largest and showiest flowers in Solanum and accrescent calyces in fruit that often completely cover the mature berry. All six species are endemic to the coastal Atlantic forests of south-eastern and north-eastern Brazil. We describe one new species, S.phrixothrix<
