CATASETUM. r 169 



C. Christyanum, Rchb. f. — A very distinct and curious 

 species, first flowered by Thos. Christy, Esq., F.L.S., of 

 Sydenham. It has stout fusiform stems, lanceolate-lorate 

 plaited leaves, and produces strong erect flower spikes con- 

 taining about a dozen flowers, the sepals and petals of which 

 are of a dull chocolate brown, the lip and column being of a 

 bright green ; it blossoms during the autumn months. — 

 Brazil.

C. mcacrocarpum, Richard. — This is a grand Orchid, and 

 ■was communicated to us by W. Macdonald, Esq., of Perth, 

 who flowered it in 1884 ; but in common with others of the 

 genus it has not received much attention though very remark- 

 able in structure. The flowers are about four inches in 

 diameter ; sepals and petals broad, pale yellowish green, 

 densely spotted with purplish brown, reminding one of those 

 of Paphinia grandis ; lip deep orange yellow, densely spotted 

 •with brown, green on the lower portion of the outside ; 

 flowers in June. There are many varieties of this plant. — 

 Tropical America, east of the Andes.

C. SCUrra, Rchb.f. — This curious plant is well worthy of 

 cultivation, owing to its compactness of habit, and the elegance 

 and perfume of its flowers. The pseudobulbs are about an 

 inch and a half high, ovate acute, becoming much wrinkled, 

 the leaves about six inches long, oblong-lanceolate, and of a 

 lively green, and the flowers five or more together in a droop- 

 ing raceme. The flowers are of pale straw colour or waxy white 

 with green veins, and they emit a most grateful perfume, which 

 has been compared to that of lemons or roses. The lip is very 

 peculiar in structure ; it is trifid, the side lobes erect with 

 bent borders, rhomboid and denticulate, the middle lobe with a 

 short broad linear stalk, expanded into a subreniform blade 

 with crisped and toothletted edges. — Bemerara ; Panama.
