Fruits not seen. + + + + +Etymology: +—The specific epithet + +infundibuliformis + +refers to the shape of the corolla, one of the distinctive features of this species. + + + + +Distribution and Habitat: +—The new species was collected in the locality of Quimbira, municipality of Italva, bordering with the town of Cardoso Moreira, in state of +Rio de Janeiro +, southeastern +Brazil +. The area is suburban, surrounded by several rural activities, such as livestock pasture and small farms. The locality is within the Atlantic Rainforest biome. + + + + + +Phenology: +— + +Collected with flowers in October and November. + + + + + +Conservation Status: +— +Critically Endangered (CR) + +. B2ab (ii,iii,iv,v), D. The area of occupancy (AOO) was calculated to be of +4 km +2 +. The AOO is less than +10 km +2 +, being known from a single locality, and by less than 50 mature individuals, placing this species in the category of Critically Endangered. It occurs in the dwindling Atlantic Rainforest, a biome much impacted in +Rio de Janeiro +over the last two centuries. Besides, the collection locality is not included in any +type +of conservation unit, leading to great concern regarding the future of this new species. + + + + + + +Paratype +: + +— +BRAZIL +. +Rio de Janeiro +: +Mun.
