In die general aspect of this plant before flowering there is little to distinguish it from Crtuctum 

 tridcnlatnni ; but its flowers arc marked by many Striking peculiarities. 



Tlic iXffuiitBSCEEtOB b a nodding many-flowcrcd raceme, proceeding from the base of the 

 pseudo-bulbs. The sepals are narrowly lanceolate and acuminate, of a greenish purple colour, which 

 varies in intensity in different specimens ; elio uppermost is pressed clow to tlic petals the two side 

 ones are turned back (ill they touch each other. Tito petals are thin, pale pink, stained with dull 

 purple, rather broader than the upper sepal, with which they are parallel, so as to form a kind of arch 

 over the column, but not baching it : sometimes however they separate, and fall backwards towards 

 the lateral sepals, or Simply spread away from the column. Such was the case in the specimen that 

 famished the accompanying drawing : so that this plant has at one time the arrangement of parts 

 found in the abolished senus Myanlhus. and at another a disposition peculiar to it*clf, 



The LI? is altogether of a new form in this genus. It has a lanceolate outline, and is hollowed 

 at its base into a deep pouch ; its edge* and point are carved inwards, and along the margin, towards 

 the base, it is bordered by a flue fringe of slender hairs. From the front edge of the pouch to nearly 

 the apex is carried a fleshy plate, planted perpendicularly upon the lip, and from four to five 1 

 deep, which, next the pouch, divides into two lobe*, but otherwise is perfectly entire except on th 

 Upper edge, which in some varieties is unequally toothed. In colour this part is variable ; in ll 

 specimen now figured it was pale greenish pink, spotted with dull but deep purple j mid in a pi 

 that flowered in the Garden of the Horticultural Society, ,t the time that this article was going 

 through the press, it was of the purest ivory white, eventually changing to cream colour. The 

 column is spotted in the variety with a spotted lip. ami nearly plain in that with the white lip; in 

 structure it is like C. tnacnhitum. 



The only Botanist* who have found this plant wild were Count Karwiuski, whose specimen* 

 exist in the Royal Herbarium of Munich, and Mr. Harlwcg ; in both case* it was observed in the 

 neighbourhood of Oaxacn. By tlic latter it was sent to the Horticultural Society, who have distri- 

 hutcd it extensively. The specimen now represented was the first that flowered in this country, and 

 was drawn in the stove of Messrs Loddigcs.
