“…Lleras (1978) ao estudar a família, destacou os frutos. Guimarães & Miguel (1985) quando do conhecimento das Trigoniaceae do estado do Rio de Janeiro informam os diferentes aspectos da deiscência das cápsulas e estabelecem dois grupos de espécies nos quais foram colocados os táxons a eles pertinentes com base em caracteres das cápsulas. Barroso et al (1999) ressaltam as informações já citadas por seus antecessores e relatam das placentas que formam seis feixes com valvas deles pendentes.…”

resumo: O estudo das Trigoniaceae revelou que os caracteres morfológicos de seus frutos podem contribuir, de maneira decisiva, na identificação em níveis genérico, específico e infraespecífico. Os gêneros Trigoniastrum Miq., Humbertiodendron Leandri e Isidodendron Fern-Alonso, Pérez & Idarraga, caracterizam-se por apresentar fruto sâmara, enquanto Trigonia Aubl. e Trigoniodendron E.F. Guim. & Miguel apresentam cápsulas. A coleta e análise de materiais frutificados, bem como a analise de extensas coleções de herbário, permitiram observar que a origem, deiscência, indumento, replum e dispersão constituem fatores diagnósticos para os táxons infrafamiliares. Neste trabalho os frutos são descritos e incluídos em grupos morfológicos. Chaves para identificação dos gêneros, espécies e variedades são apresentadas bem como ilustrações dos principais tipos de frutos.

“…The genus Prepusa Martius, which belongs to the tribe Helieae, is endemic to Brazil and contains only six species, all restricted to montane environments (Fraga et al 2014;Flora do Brasil 2020). As these species have a restricted distribution with fragmented populations, most of them are red-listed (Guimarães et al 2018; Flora do Brasil 2020) (e.g. Prepusa alata Porto & Brade and Prepusa connata Gardner-critically endangered, CR; Prepusa hookeriana Gardner and Prepusa viridiflora Brade-endangered, EN; Prepusa montana Mart.-vulnerable, VU).…”

Reproductive biology of Prepusa hookeriana (Gentianaceae): an endangered species of high-altitude grasslands in Brazil

et al. 2020

The genus Prepusa Martius is endemic to montane regions of Brazil and comprises only six species, most of them endangered. Although studies on reproductive biology are necessary to increase knowledge of this genus and to implement conservation plans, to date, no such studies have been conducted. This study assessed the floral biology, breeding system, and pollinators of Prepusa hookeriana, an endangered species of high-altitude grasslands. We perform field observations and manual pollination experiments. Certain floral traits of this species appear to be associated with hummingbird pollination, although ornithophily is unusual in Gentianaceae. Even though cross-pollination is favoured by the presence of movement herkogamy and protandry, both prior and delayed autonomous self-pollination were observed. The only pollinator observed was the hummingbird Amazilia versicolor. Prepusa hookeriana did not show pollen limitation in the year of study. The absence of pollen limitation is related to the high reproductive success of pollination due to visits, not to autonomous selfpollination. However, we share the idea that the ability of autonomous selfing can provide a backup to cope with occasional pollination failures.
