AA'D THEIR MANAGEMENT. 113 



Chtjsis. 



C. aurea (LindL). — A species having fusiform pseudo-bulbs, 

 about 9in. long, and broad, lance-shaped leaves. The flowers 

 are tawny yellow, somewhat cup-shaped, and the tips of the 

 segments are marked with crimson on the inside. It remains in 

 blossom about a month. Colombia, 1834. (B. M., t. 3617.) 



C. bractescens (LindL). — A larger plant than C. aurea, the 

 pseudo-bulbs being thicker, and the leaves broader. The flowers 

 are developed about six together on a semi-drooping raceme, 

 each one being nearly 3in. across ; the sepals and petals are 

 spreading, overlapping, and pure white ; the lip is white, 

 blotched inside with yellow, and marked with crimson lines and 

 fleshy, teeth-like projections ; the flowers appear in April and 

 May, each lasting about a fortnight. Mexico, 1840. (B. M., 

 t. 5186.) 



C. Bruennowiana {Rchb. /.). — This is much in the way of 

 habit of C. aurea ; it bears several medium-sized pinkish flowers. 

 It is a native of Peru, and was introduced more than forty years 

 ago, and again as recently as 1893. Syn. C. Oiveniana. 



C. Limminghei {Rclih. /).— This has pseudo-bulbs ift. long, 

 broad, lance-shaped leaves, and arched racemes of large flowers, 

 which are white, with purple-rose tips ; the lip is yellow, striped 

 with rose inside, the front being wholly purple-rose, with blotches 

 and stripes of a deeper colour. It flowers freely in May and 

 June. Central America. (B. M., t. 5265.) 



C. Oweniana [Horf.). — A synonym of C. Bruennowiana. 



The following are Hybrids : 



chehoni braciescens and Icevis (Veitch). 



lanalevensis bractesLens and Sedenii (Veitch). 



Seden'ii Limminghei and bractescens (Veitch). 



CHYTROQLOSSA. 



Two species of epiphytal Orchids, of the tribe Vandece, are 

 included in this genus, founded by the younger Reichenbach. 

 They have very short stems, and are natives of Brazil. The 

 name is derived from chytros, a well, and glossa, a tongue, 

 and has reference to the hollow at the base of the lip. 

 C. aurata, having green and white sepals, white petals, and 

 the base of column and lip purple-spotted, has been intro- 

 duced, but is rare in cultivation. Flowers mediocre, 

 shortly pedicellate ; sepals and petals similar, free, spreading; 

 lip continuous with the base of the column, obscurely
