- A inflorescencia com flores laxas, as bracteas do escapo e primarias elipticas a largo-elipticas, a raque e o escapo glabrescentes e expostos, as sepalas longas e o ovario cilindrico e sulcado sao caracteristicas da especie. No entanto, trata-se de uma especie polimorfica, especialmente na forma da roseta, na morfologia foliar e da inflorescencia, e na coloracao das sepalas e petalas, o que e refletido no grande numero de binomios associados a especie (16 sinonimos e sete variedades). Por este motivo, optou-se neste trabalho, por adotar a taxonomia em nivel especifico.
a especie distribui-se nos Estados de Goias, Bahia, Minas Gerais, Espirito Santo, Rio de Janeiro, Sao Paulo, Parana e Santa Catarina, na Floresta Pluvial Atlantica, restinga, campos de altitude (Smith & Downs 1979; Fontoura et al. 1991; Moura et al. 2007) e campos rupestres (Versieux & Wendt 2006). No Rio de Janeiro e bem representada em quase todas as restingas, nas florestas montanas e nos campos de altitude da regiao serrana de Macae. —See Barros & Costa 2008
- Translated by Butcher
The inflorescence with lax flowers, scape and primary bracts elliptic to wide elliptic, the rachis and scape glabrescent and exposed, the long sepals and the cylindricaland sulcate ovary are characteristic of the species. However, it is a polymorphic species, especially in the form of the rosette, in the morphology of the leaves and the inflorescence, and in the colouration of the sepals and petals, which is reflected in the large number of binomials associated with the species (16 synonyms and seven varieties). For this reason, we have chosen in this work, to adopt the taxonomy at a specific level.
the species is distributed in States of Goiás, Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Paraná and Santa Catarina, in the Atlantic Pluvial Forest, restinga, high fields (Smith & Downs 1979; Fontoura et al. 1991; Moura et al. 2007) and rupestral fields (Versieux & Wendt 2006). In Rio de Janeiro it is well represented in almost all of the restingas, in the mountain forests and in the high fields of the highland area of Macae. —See Barros & Costa 2008
