and three-quarter inches broad, emarginate and apiculate, 

 the smaller lateral lobes being almost semicircular, and placed 

 behind the distinct basal isthmus connecting the front with 

 the hinder portion, the whole being of a bright clear yellow. 

 It produces these branching panicles of flowers during the 

 dull months of autumn and winter, which gi'eatly enhances 

 its value, and it lasts six weeks in bloom. There have been 

 several importations during the last three years, which has 

 made this fine Orchid more plentiful. It should be grown in 

 the Mexican house. — Mexico; Guatemala ; Meclwacan.

Syn. — 0. Barkeri; Odontoglossum tigrinum, 



0. tigrinum unguiculatum, Lindley. — A pretty winter- 

 blooming variety, in which the somewhat smaller flowers are 

 produced on a long branching scape, three or four feet high, 

 and last a long time in perfection ; they are of a pale green 

 colour, speckled with crimson, the lip clear yellow. It 

 succeeds best potted in good fibrous peat. — Mexico. 



Syn. — 0. ionosmum. 



0. trilingue, Lindley. — A very peculiar plant, still rare in 

 collections, and very much resembling 0. serratum, to which, 

 indeed, it is nearly allied. The flowers grow in semiscandent 

 panicles, rather sparsely furnished ; the lateral sepals are un- 

 guiculate, connate at the base, elongate lanceolate and undu- 

 lated, the dorsal one roundish ovate, crisped, the claw auricu- 

 late, all of a rich reddish brown; the lip is dagger- shaped, 

 brown, edged with light yellow, with a yellow crest. It should 

 be potted in fibrous peat, and grown in the cool house. — Peru.

0. Taricosum, Lindley. — A very beautiful and well-marked 

 species, having ovate oblong subtetragonal furrowed pseudo- 

 bulbs two to four inches high,ligulate lanceolate bluntish keeled 

 leaves, and stout glaucous panicles two to three feet long, 

 literally covered with large showy flowers, of which the small 

 oblong acute incurved sepals and reflexed obovate petals are 

 pale dull green banded with dark brown, these being quite 

 eclipsed by the large roundish or transversely reniform obso- 

 letely four-lobed lip, which is flatly expanded and of a clear 

 bright yellow. It flowers during the months of October and 

 November. — Brazil.
