“…Shifts to the hummingbird from the bee syndrome involved the acquisition of floral features, such as the red color and the straight tubular corolla, that are considered to play a role in deterring insect visitors that may rob nectar (Heinrich and Raven, 1972;Raven, 1972;Schemske and Bradshaw, 1999;Chittka et al, 2001). Field observations confirm hummingbird specificity for a few red tubular Sinningia and Vanhouttea species (Snow and Teixeira, 1982;Sazima et al, 1996;Chautems et al, 2000;Buzato et al, 2000;Vasconcelos and Lombardi, 2000). On the contrary, shifts to bee syndrome involve numerous colors (blue, purple, yellow, and white) independently of campanulate or funnel-shaped flowers.…”

“…Here, we have used a portion of the nuclear plastid-expressed glutamine synthetase gene (ncpGS, introns 7-10), as well as four plastid intergenic spacers (trnT-trnL, trnL-trnF, trnS-trnG, atpB-rbcL) and two introns (within trnL and rpl16) to produce a nearly complete species-level phylogenetic tree for the members of Sinningieae. We sampled all known species (Wiehler, 1983(Wiehler, , 1984Chautems, 1990Chautems, , 1991Chautems, , 1995Chautems and Weber, 1999;Chautems et al, 2000) with the excep-[Vol. 90 AMERICAN JOURNAL OF BOTANY tion of six taxa for which we could not obtain suitable material (i.e., S. helleri, S. schomburkiana, S. sulcata, and three unpublished new species).…”

For nearly all species in the three genera of tribe Sinningieae (Gesneriaceae), Sinningia, Paliavana, and Vanhouttea (mostly in southeastern Brazil) plus 10 outgroups, we have sequenced six non-coding DNA regions (i.e., plastid intergenic spacers trnT-trnL, trnL-trnF, trnS-trnG, atpB-rbcL, and introns in the trnL and rpl16 genes) and four introns in nuclear plastid-expressed glutamine synthetase gene (ncpGS). Separate and combined analyses of these data sets using maximum parsimony supported the monophyly of Sinningieae, but the genera Paliavana and Vanhouttea were found embedded within Sinningia; therefore a new infrageneric classification is here proposed. Mapping of pollination syndromes on the DNA-based trees supported multiple origins of hummingbird and bee syndromes and derivation of moth and bat syndromes from hummingbird flowers. Perennial tubers were derived from perennial stems in non-tuberous plants.

-(Gesneriaceae of Espinhaço Range in Minas Gerais, Brazil). Gesneriaceae is predominantly tropical, and comprises nearly 3,000 species. The Espinhaço Range include parts of Minas Gerais and Bahia States and presents several types of vegetation, including the "campos rupestres" (the dominant one). The northern limit of the study area is Espinosa and the southern is Serra de Ouro Branco. This work was carried out based on bibliography survey, herbarium material, field observations and gatherings. The floristic survey revealed 21 species belonging to six genera: Anetanthus, Codonanthe, Gloxinia, Nematanthus, Paliavana and Sinningia. Identification keys, descriptions and comments of taxa are presented elaborated, as well as maps of geographic distribution and illustrations of the species.
