C. tonosmum ; foliis distichis coriaceis ensiformibus obliqué retusis, paniculá 
patente, sepalis petalisque obovatis obtusis subzequalibus, labelli hastati 
carnosi pubescentis laciniá intermedia cordato-triangulari calcare conico, 
columná pubescente antice bidentatä. 
A native of Manilla, whence it was sent to Messrs. 
Loddiges by Mr. Cuming. It flowered in the Hackney 
Nursery in March, 1844. 
The flowers are in an open panicle, about an inch across, 
flat, with five obovate equal obtuse lobes, yellow with cinna- 
mon-brown blotches. The lip is white with a few red streaks, 
three-lobed, with the basallobes acute and smaller than the 
middle one, which is cordate triangular acute, and much 
larger than they are. The flowers smell pleasantly of violets. 
Fig. L. represents a lateral view of the column and lip; 
2. the same seen from the front ; 3. the pollen-masses, caudicle, 
and gland; 4. a cross section of a pair of pollen-masses. 
The flowers are much larger than those of any species 
previously described.
