TR[CHOSMA. 



This monot_\-pic genus of the tribe Epidcudi-cic is nearly 

 alHed to Civlogytic, rrom which it chiefly differs in its 

 erect, tufted stems ; it has afso been included under Eria. 

 The species is an epiphyte, and a native of the Sikkim 

 Himala3-a and Khasia Alountains, whence it was intro- 

 duced in 1840. The name given by Lindle)- is from treis, 

 three, and chosina, a division ; in allusion to the three- 

 lobed labelhun. 



Culture. — This is one of the most easily-cultivated of 

 Orchids. It delights in a cr)ol, moist atmosphere, and 

 may be grown with the Odontoglossums. Imported 

 plants should be ke[)t in the intermediate-house until 

 full}- established. The)' should be potted in fibrous peat 

 and sphagnum, and, as copious supplies of water are 

 necessary during growth, perfect drainage is essential. 

 Although less water is needed in winter, tlie roots must 

 at no time be allowed to remain dry. Provided a 

 vigorous, healthy growth be obtained, this Orchid 

 seldom fails to flower. 



T. suavis (LiiidL). — An extremely pretty, free^lowering plant 

 that certainly deserves more notice than it has hitherto received 

 It has slender, tapering stems about Sin. high, surmounted by 

 two bright green, oblong leaves, between which the four- to 

 eight-flowered raceme is produced. The flowers are liin. in 

 diameter, and delightfully fragrant. The sepals and petals are 

 lance-shaped, creamy-white ; the lip is three-lobed, the side lobes 

 are white, striped with brownish-crimson, and the middle one 

 crested, yellow, with crimson at the edges. It flowers in October 

 and November. (B. K., 1S42, t. 21.) 



TRIQONIDIUM. 



Botanically interesting Orchids belonging to the tribe 

 VandecB. Lindley's name is from trigone, a triangle, and 

 eidos, like, and has reference to the triangular form of 

 several parts of the plants. The species require a warm 

 intermerliate-house, suspended in baskets, the compost con- 

 sisting of good fibrous peat and sphagnum. They like a 

 fairly light position. 



UROPEDIUM. This genus, founded by Lindley, is now 

 included under Selenipedium.
