EPIDENDREEE. FH 
L. DINEMA. 
Dinema. Orch. Sceletos, p. 6. 
Sepala et petala subzequalia, herbacea, patentia. Labellum majus, mem- 
branaceum, indivisum, unguiculatum, cum basi columne accretum. 
Columna nana, bicornis. Anthera bilocularis. Pollinia 4, per paria 
caudiculis duobus replicatis adnata. Herba epiphyta, rhizomate re- 
pente annulato pseudobulbifero. Folia coriacea. Flores solitarii, ter- 
minales, pedunculo vaginato. 
This genus differs from Isochilus chiefly in its labellum being large, 
membranous and extremely different in appearance from the petals ; and 
in these last, and the sepals being spreading not connivent. It is distin- 
guished from Epidendrum by its short two horned labellum.

LI. ENCYCLIA. 
Encyclia. Hooker in Bot. Mag. t. 2831. 
Sepala et petala subzqualia, conniventia. Labellum (posticum) cucul. 
latum, columnam involvens, apice trilobum, basi callosum. Columna 
libera, semiteres, clavata, cum labello parallela. Anthera 4-locularis, 
septis marginatis. Pollinia 4, collateralia, caudiculis totidem revolutis. 
Herba epiphyta, pseudobulbosa, Epidendri facie, foliis coriaceis. 
Inflorescentia terminalis. 
This genus differs from Cattleya in its small half-closed flowers, the 
labellum of which is posterior with a great callus at its base, and also in 
its panicled flowers; otherwise it approaches it very nearly. From Epi- 
dendrum it cannot be distinguished either by its herbage, or inflorescence, 
and in its fructification is so similar to that genus that with the exception 
of its four celled anther, and cucullate labellum, it possesses no peculiar 
character. The posterior labellum is observed in many undoubted Epi- 
dendra, and in some species of the same genus the cohesion between the 
lip and the column is very slight. So slight indeed are the marks of dis- 
tinction between Encyclia and Epidendrum that Dr. Hooker's sécond 
species of the former (E. patens) unquestionably belongs to the latter 
genus ; see Epidendrum odoratissimum.
