in front. Introduced from Caracas in iSSi, The flowers are 

 produced in early spring. It should be grown in the cool-house, 

 and always be kept moist. By some authorities this is regarded 

 as synonymous with O. constricliiin. 



O. sceptrum (Rchb. /). — A variety of O. lutco-piirpureum. 



O. Schlieperianum (^Rclib. /.). — In habit of growth and 

 general appearance this very useful species resembles O. graiidc ; 

 but the flowers, though like those of that species in form, are 

 different in colour ; they are borne upon erect scapes, several 

 together, and are pale yellow, blotched and barred with a deeper 

 shade of the same colour, or almost reddish-brown. A native 

 of Costa Rica; introduced in 1856. It requires the same treat- 

 ment as O. graiide. Syn. O. Inskayi inacraiithiiin (under which 

 name it was described by Lindley). (G., t. 605.) 



O. Schroederianum {O'Brien). — A synonym of Miltonia 

 Schrxdej-iaiia. 



O. tripudians {Rchb. /.). — A well-marked and free-flowering 

 species, supposed to be of hybrid origin. In leaf-characters it 

 resembles O. iioblk. The spike is arching, rarely branched, and 

 the flowers are 2-rjin. across, chestnut-brown and yellow, the 

 former colour being in blotches ; lip white, with a jagged edge, 

 sometimes blotched with rose. Introduced from Colombia in 

 1S69. When wild it is said to flower all the year round, but 

 under cultivation it usually blooms only in autumn. It is some- 

 what variable in the markings of the flowers, and is not always 

 admired. It requires cool treatment. 



O. triumphans (Rchb.fi). — An easily-managed large-flowered 

 species, and one of the most popular of the genus. Pseudo- 

 bulbs 3in. to 4in. long, two-leaved. Leaves ift. to i^ft. long, 

 bright green. Scape arching, many-flowered, branched, and from 

 2ft. to 3ft. in length. Flowers 3in. to 4in. across, thick in 

 substance ; sepals and petals bright yellow, blotched with deep 

 brownish-crimson ; lip oblong, with a narrow, tail-like tip, the 

 edges toothed, the front portion being cinnamon-brown, and the 

 basal half pure white, with a yellow centre ; the crest, which is 

 usually white, has two long teeth. The plant blossoms during 

 March, April, and May. It should be grown along with 

 O. crispuin and O. nobik, with which it is often found associated 

 m a wild state. It is a native of Colombia, where it was 

 discovered by Linden in 1842, at an altitude of 8500ft. ; it does 

 not appear, however, to have been in cultivation in England till 

 about twenty-five years afterwards. (Batem. Monog., t. 23.) 



There are several varieties of this species, the most prominent 

 being O. t. aiireum, in which the yellow, has suppressed the
