Abstract

Nierembergia (Solanaceae) contains 20 species found primarily in South America, with one species occurring disjunctly in Mexico. A pollination system not found elsewhere in the Solanaceae typifies this genus. In most species, nectaries are absent, but oil-producing elaiophores are present on the corolla limb and these attract oil-collecting bees. Molecular phylogenetic hypotheses based on nuclear ITS and chloroplast rpl16 intron data support the monophyly of Nierembergia, which is sister to a clade composed of Bouchetia plus Hunzikeria. The data reconstruct two clades within the genus: one composed primarily of herbaceous species with broad stigmas and the second containing woody species with crescent-shaped stigmas. Morphological homoplasy is frequent among the species of the herbaceous clade, while the woody clade is morphologically cohesive. New chromosome counts are reported for eight species of Nierembergia (including three varietals) and previous counts are confirmed for six Nierembergia species and for Bouchetia anomala, Leptoglossis linifolia, and Petunia axillaris.
