GLOSSARY. 
taken for O. Cervantesii. It is, however, readily known by its 
wingless column, and especially by the presence of a very large 
yellow appendage seated at the base of the lip, and scarcely 
shorter than the column. Such an appendage exists in all the 
Tooth-tongues, but it is usually inconsiderable, and never to be 
compared in size with this. We are unacquainted with the native 
country of this species, but its great resemblance to 0. Cervan¬ 
tesii, nebulosum, Rossii, &c., indicates Mexico. The specimen 
now described, was received from C. B. Warner, Esq., in Septem¬ 
ber last.— Bot. Reg. 
Malachadenia clavata (Lindley). A Rio plant, in the collection 
of Mr. Bateman, where it bloomed first, in 1839. The plant is 
a very singular one, though it has little beauty to recommend it, 
and Mr. Bateman remarks it is the only epiphytal orchidaceous 
plant I know which emits a positive stench, and that too at all 
hours, by night and day. In the stove it resembles the foulest 
carrionIt has a creeping, bulbiferous rhizoma, and small 
flowers, borne on a spike five or six together, green, richly spotted 
with brown.— Bot. Mag.
