Bulbophyllum involutum Borba, Semir & F. Barros (Orchidaceae), a New Species from the Brazilian "Campos Rupestres"

“…In the field, Bulbophyllum involutum is easily recognized by its purple inflorescence (flowers, bracts, scape, and rachis), always with a single flower at anthesis, while B. warmingianum, B. longispicatum, and B. ipanemensis have green or greenish yellow inflorescences, with three to five flowers simultaneously at anthesis, as can be seen in the colored plates and descriptions of these species (Warming, 1883;Cogniaux, 1902;Hoehne, 1938). Those traits also aid in the recognition of B. involutum in herbarium material, since the purple coloration remains in its sepals, scape, and bracts.…”

Phylogenetic placement, taxonomic revision and a new species of Nothostele (Orchidaceae), an enigmatic genus endemic to the cerrado of central Brazil

“…In that drawing, the pollinarium was depicted as consisting of two (instead of four, as usual in Cranichidinae) clavate pollinia with distinct, slender ‘caudicles’ joined at their tips to a globular, hooked viscidium. However, in the plate of this species published by Warming (1884), the pollinarium was represented as two longitudinally divided pollinia that gradually attenuate towards the apex; the viscidium was not attached at the apex of the pollinia, but in two views of the column it is globular and situated at the apex of the rostellum. Szlachetko (1995) likewise included Nothostele in Cranichidinae s.s. , as did Szlachetko & Rutkowski (2000: 293), who described its viscidium as having ‘a hook‐like upcurved apex transformed into a hamulus’.…”

“…& Warm. (Reichenbach, 1881) based on plants collected by Warming in 1864 in Lagoa Santa, Minas Gerais, Brazil (Warming, 1884). Cogniaux (1893–1896) transferred it to Stenorrhynchos Rich.…”

Flora da Serra do Cipó, Minas Gerais: Annonaceae

“…Na Serra do Cipó, forma moitas de grande diâmetro no cerrado do Vale da Mãe d'Água e no antigo km 116. Sua área de ocorrência são os cerrados de Lagoa Santa (Warming 1873(Warming , 1892 e Serra do Cipó, e da região de Caldas e Serra da Canastra até Brasília. É caracterizada pelo hábito e pelas flores desproporcionalmente grandes, parecendo brotar do solo.…”
