Orchidaceae, Encyclia, Encyclia pachyantha, Encyclia paraensis, Amazon, Brazil, Pará. Abstract: A new Encyclia (section Encyclia), from Amazonian Brazilian Region, is described. This new species of Encyclia grows in the surroundings of Belém City, state of Pará, it has been already known since some time by cultivators in Belém. |
Encyclia pachyantha |
First,
it was considered as Encyclia pachyantha (Lindl.) Hoehne because
the identification asked for the first author has been done from a photography,
without analyzing neither the flowers nor the plant. Encyclia pachyantha is a plant which was described as coming from Guyana and is also found in Brazil, in the state of Amapá. However this new Encyclia is smaller than Encyclia pachyantha: at about a quarter of the plant size and at two thirds of flower size; the scent is particular, the floral characteristics are different and an homogenous population could be observed: Everything brings to conclude that this is a new species. |

Encyclia
pachyantha (Lindl) Hoehne similis, sed: semper floris 1/3 minoris,
sepalo dorsali obovato-lanceolato; sepalis laterabilus leviter falcatis;
petalis ovobatis, marginis laevis; labello trilobato, lobo mediano suborbiculato,
disco cum callis bilamelalis albis, lobis lateralibus ligulatis et linearis,
in Encyclia pachyantha arcuatis sunt; columna biauriculata. |
Discussion:
When this species is examined, immediately we think about the Encyclia pachyantha however when it is detailed analyzed, we conclude that it is a matter of a good species. Regarding to Encyclia remotiflora (C. Schweing.) Carnevali & Ramirez, the differences equally clear: this last species has just one leaf, longer inflorescence and the flowers are more separated one from the others. |
Encyclia
paraensis |
We can notice that the plant size is just a quarter of Encyclia pachyantha size and the size of the flowers is, at about, 2/3, the petals and sepals are longer, the petals are orbicular and the margins are smooth, while the flowers of Encyclia pachyantha have the petals with undulated margins and acute edge. The lip of the new species presents narrower lateral lobes with round apex while in Encyclia pachyantha, they are wider with truncate apex. The wings of the column are wider and projected towards the top while in Encyclia pachyantha, they are a little more down projected; besides, the anther of Encyclia pachyantha has a square apex while in Encyclia pachyantha, it is bifurcated. |
