ODONTOGLOSSUM. 465 



the petals having a single brown line at the base, and the 

 sepals being washed with reddish mauve outside, and having 

 a few large dark brown-purple blotches inside; blade of lip 

 pandurate, white changing to lemon with a few crimson 

 blotches. — New Grenada. 



0. tripudians, BcM. f. et Warsc. — Though scarcely occu- 

 pying a place in the front rank of Odontoglots, this is a 

 really handsome and well-marked species, and, moreover, it 

 is very free-flowering. In growth it resembles 0. Pesca- 

 torei, along with which it is frequently imported. The 

 pseudobulbs are ovoid-oblong compressed, the leaves nar- 

 row lanceolate acuminate, and the flowers, which grow in 

 simple many-flowered racemes, are remarkable for the dull 

 yellow green of the exterior surface and the bright colours 

 of the inner surface. The sepals and petals are oblong 

 elliptic acuminate, the former almost wholly of a rich maroon- 

 brown with just the base and tip only yellow, the latter 

 golden yellow with two or three broad unequal blotches of 

 maroon brown ; the lip oblong quadrate, constricted in the 

 middle, the basal part obscurely crenate, the broader rounded 

 apiculate apex erose at the edge, the colour white, having the 

 region round the calli spotted with a beautiful purplish violet. 

 The calli consist of about ten keels radiating from the claw, 

 the four inner ones produced on to the surface of the basal 

 lobe, and each ends in a spinous process ; the wings of the 

 column are deeply toothed. The plant flowers during the 

 autumn months. — Peru.

0. tripudians OCUlatum, Pckh. f. — A very beautiful variety^ 

 first flowered by J. Day, Esq., Tottenham. It has large 

 glossy flowers, of which the sepals are almost entirely chest- 

 nut brown with yellow tips ; the petals yellow banded with 

 chestnut brown ; and the pandurate lip white with several 

 violet blotches around the crest, and a large brownish violet 

 blotch on the anterior part, the margin denticulate and 

 crisped. — Peru. 



_ 0. tripudians xanthoglossnni, BcM. f. — This variety is 

 distinct from the preceding, having the lip wholly yellow with 

 mauve blotches, the crests only pure white, thus forming a 

 pretty contrast with the other varieties in our gardens. — Peru.
