“…Os principais estudos botânicos para seus representantes epífi tos no Brasil foram realizados por Loefgren (1915Loefgren ( , 1917 e Ritter (1979), além de trabalhos regionais: Lombardi (1991Lombardi ( , 1995 para o estado de São Paulo, Freitas (1992) para o Rio de Janeiro, Geraldino et al (2010) para o Paraná, Scheinvar (1985) para Santa Catarina.…”

“…On a survey of Cactaceae for the state of Rio de Janeiro presented by Calvente et al (2005) only one specimen (holotype) was examined. Zappi et al (2007) Zappi et al (2007), Bauer & Waechter (2006), Lombardi (1991) and Taylor & Zappi (2004).…”

“…Bauer & Waechter (2006) described the fruits as magenta with 4-5 mm diameter, Zappi et al (2007) described the fruits as white with ca. 7 mm diameter and Lombardi (1991) cited only white fruits.…”

“…In a survey conducted in Rio de Janeiro State, Calvente et al (2005) showed the occurrence of 45 species, the genus Rhipsalis being the most representative, with 23 species. Lombardi (1991) also conduted a survey in São Paulo State and described 16 species of Rhipsalis with cylindrical cladodes.
