Plate 294. 
ODONTOGLOSSTJM CEBVANTESII. 
The readiness with which the family of Orchids, to which the 
subject of our present. Plate belongs, has submitted to what is 
called the u cool treatment ” has invested them with peculiar 
interest and added to their value, while the magnificent Mono¬ 
graph of Mr. Bateman has doubtless given an increased impetus 
to their growth. Having already figured 0. Pescatorei splendens , 
we have added now another which has been much exhibited 
during the present season, and especially at Mr. Low’s at Clap¬ 
ton, to whose courtesy we owe the opportunity of figuring it.* 
There are three Odontoglossums which are so very similar 
in their appearance as to be deemed by some of our first Orchid- 
growers as only varieties of the same species: these are, 0. 
Cervontesii , 0. Ehrenbergii , and 0. membranaceum , the two latter 
being referred by Mr. Anderson, of Meadow Bank, to 0. Cer - 
vantesii. We cannot do better than give his description of the 
plant figured. 
44 0. Cer vantesii, a very distinct and charming species from 
Mexico, with roundish pseudobulbs about an inch and a half 
in diameter, producing a short raceme from the matured growth 
of from five to eight flowers of a pinkish-white with very pro¬ 
minent crimson lines arranged in concentric circles round the 
base and covering nearly one-half of the radius of the flower; 
labellum large, white, and of a semicircular outline. This is a 
slow-growing species, and requires more than ordinary care; 
time of flowering, March to May.” 0. Ehrenbergii differs only 
in being a little less in point of size and not having so many 
concentric rays of crimson, which are also of a fainter tint, while 
# O. Gervantesii was introduced about 1845.
