Coryanthes. 



C. maculata (Hook.). — A species with clustering, striated 

 pseudo-bulbs, 5in. to 6in. in length, and tapering upwards. The 

 leaves are two in number, broadly lance-shaped and somewhat 

 membranous. The flowers are borne six to ten together on 

 a piendent scape, and are of a [lale brownish-yellow, the lip being 

 tinged and spotted with purple. This species is found growing 

 on the branches of trees in Tropical -America, and was intro- 

 duced into this countr)' in 1S29. (B. '\l., t. 3102.) 



A'ar. punctata is an improvement on the type ; the sepals and 

 petals are thickly spotted with deep wine-purple, and the lip 

 is also blotched with the same colour, the pouch being almost 

 entirely purple. 



C. speciosa (Hook.). — In the size and form of its pseudo- 

 bulbs and foliage this resembles C. iiiaLiilata. The scape is 

 pendent, three-flowered, and each flower is about 3in. across, 

 of a dull pinkish colour, spotted with dark brown, faintly, 

 and not agreeably scented. This species is a native of 

 Demerara, where it is common on large trees, forming large 

 masses of closely-woven roots and pseudo-bulbs, which are 

 usually the abode of families of irritating ants. Collectors 

 find great difficulty in procuring these plants because of 

 the pertinacity of the ants. All the Coryanthes have this 

 character. 



CORYCIUM. 



About ten species of cool-house, terrestrial, South 

 African Orchids, of the tribe Ophrydcoc, are included in the 

 "enus Corycii'.m ( Si^'.]. Flowers small or mediocre, nume- 

 rous, in a dense spike ; dorsal sepal and petals connate, 

 form'ing a helmet 'hence the generic name — from korys, a 

 helmet;; lip erect or incurved, the claw adnate to the 

 column.' The cultural conditions are similar to those for 

 Disa. It is questionable if any of the species are in cultiva- 

 tion. 



CORYMBIS. 



Tall, leaf)-, stove, terrestrial Orchids, of the tribe Ncottica', 

 broadly dispersed through the tropics of the East. Flowers 

 mediocre or rather large, corymbose ^a characteristic that is 

 responsible for Thouars' name— from koryinbos, a corymb), 

 sub-sessile ; sepals, petals, and lip linear ; lip channelled,
