“…Relationships between the northern and the Central Andes and the Brazilian highlands have been suggested for Tibouchina (Melastomataceae; Michelangeli et al, 2013), a connection also retrieved in phylogenetic studies on Elapghoglossum (Dryopteridaceae; Vasco et al, 2009), Sinningia (Gesneriaceae; Perret et al, 2006), Macrocarpaea (Gesneriaceae; Struwe et al, 2009), and Bromelioideae (Bromeliaceae; Givnish et al, 2014). The latter is the only dated dispersal scenario available (∼8 Ma; Givnish et al, 2011).…”

“…For the tribe Cinchoneae (Rubiaceae), Antonelli et al (2009) suggested that diversification at midelevation habitats in the northern and Central Andes during the Middle and Late Miocene was favored by ecological adaptation to higher altitudes. New World Gesneriaceae have a center of Perret et al (2013), the latter radiation accounts for more Andean species than any other clade of Gesneriaceae. Diversification of the genus Hedyosmum (Chloranthaceae) in the Northern Andes has been dated to ca.…”

“…In contrast, a few species occur in permanently water-logged marshes and peatbogs, and so the entire genus can be regarded as occupying environments with very diverse water availability (Perret et al 2006;Chautems 2008). The flowers of Sinningia, like those of Vanhouttea, mostly display long and narrow corolla tubes that are adapted for hummingbird pollination (SanMartin-Gajardo & Sazima 2005a).…”

Taxonomy of Sinningia Nees (Gesneriaceae) in Rio Grande do Sul, southern Brazil

The genus Sinningia belongs to the Neotropical tribe Gesnerieae, subtribe Ligeriinae, presently consisting of only three genera, Paliavana, Sinnigia and Vanhouttea. These genera were separated from a larger concept of tribe Gloxinieae based on phylogenetic studies with molecular data. In Rio Grande do Sul, southern Brazil, 12 species and one natural hybrid of Sinningia have been recorded. Species of Sinningia in this area are erect or ascending herbs or subshrubs arising from underground or partially exposed tubers. They grow in very distinct ecological conditions, from water-saturated marshes to dry grasslands or shrublands, but most often in rupicolous or epiphytic habitats commonly associated with forest environments. In this review we provide an identification key to the species level and morphological descriptions and illustrations, comments on taxonomic aspects, distributional maps and IUCN Red List Categories and Criteria for all twelve species. Additionally, we designate lectotypes for S. allagophylla and S. sellovii and consider the recently described S. lutea as a synonym of the highly variable S. allagophylla.

“…The genus Paliavana Vandelli (Gesneriaceae, Sinningeae) has species with characteristics mainly associated with the floral syndromes melittophily, ornithophily and chiropterophily (Wiehler 1983;Smith et al 1997;Perret et al 2001Perret et al , 2003Perret et al , 2006Perret et al , 2007Zimmer et al 2002), and studies on Paliavana sister species may provide insights for the role of pollinators in the evolution of the pollination systems of these species (SanMartinGajardo & Sazima 2005). Species of this genus have fl owers that are diversifi ed in form, color and nectar sugar composition, features that may be associated with differe nt groups of pollinators (Wiehler 1983;Perret et al 2001;SanMartin-Gajardo & Sazima 2005).…”

RESUMO -(Biologia da polinização de Paliavana tenuifl ora (Gesneriaceae: Sinningeae) no nordeste do Brasil). No presente estudo a biologia fl oral, o sistema reprodutivo, os visitantes e os polinizadores de Paliavana tenuifl ora foram analisados em campos rupestres na Chapada Diamantina, Mucugê, Bahia, Brasil. Paliavana tenuifl ora é um arbusto com fl ores campanulares azul-violeta, com antese às 11:00 h, e duração das fl ores por aproximadamente seis dias. Grandes quantidades de néctar são produzidas (médias de volume 15,5μl, concentração 22,7% e teor de açúcar 5,0 mg μL -1 ). A produção de néctar não está relacionada com o período do dia, mas a concentração variou com o volume. A espécie é autocompatível, mas a formação de frutos depende de polinizadores. Apesar do néctar estar disponível de dia e de noite, P. tenuifl ora se encaixa na síndrome de polinização por abelhas e, de fato, é polinizada por Bombus brevivillus. Entretanto, o beija-fl or Phaethornis pretrei pode ser considerado polinizador ocasional, devido a seu comportamento e a baixa freqüência de visitas. Os resultados sugerem um sistema de polinização misto, porém a importância de P. pretrei como polinizador precisa ser mais bem avaliada. Palavras-chave: Campos rupestres, polinização, sistema reprodutivo, Bombus brevivillus, Phaethornis pretrei, Bahia ABSTRACT -(Pollination biology of Paliavana tenuifl ora (Gesneriaceae: Sinningeae) in Northeastern Brazil). In this study the fl oral biology, breeding system, visitors and pollinators of Paliavana tenuifl ora were analyzed in campos rupestres in the Chapada Diamantina, Mucugê, Bahia, Brazil. Paliavana tenuifl ora is a shrub with blue-violet, bell-shaped fl owers, with anthesis at 11:00 h; the fl owers last about six days. Large amounts of nectar are produced (volume average 15.5μL, concentration 22.7% and sugar content 5.0 mg mL -1). The amount of nectar is not related to the time of day, but concentration varied with volume. The species is self-compatible, but fruit set depends on pollinators. Although nectar is available by day and night, fl owers of P. tenuifl ora fi t the bee pollination syndrome, and are actually pollinated by Bombus brevivillus. However, the hummingbird Phaethornis pretrei can be considered an occasional pollinator, due to its behavior and low frequency of visits. Our results suggest a mixed pollination system, although the importance of P.pretrei as a pollinator remains to be better evaluated.
