184 oechid-grower's mantjai. 



green, producing long pendulous racemes of ricUy-coloured 

 flowers, which, in some instances, are very grotesque in 

 appearance. As the flower spike is pendulous and produced 

 from the base of the bulbs, the plants are best grown in 

 baskets with peat and moss ; indeed they are extremely 

 liable to injury if grown in pots. The temperature of the 

 cool end of the Cattleya house suits them well ; they enjoy 

 a liberal supply of water during summer, both on the foliage 

 and to the roots, but a very little will suffice in winter. The 

 bulbs, however, should not be allowed to shrivel. 



G. atropurpurea. — This is an old but very handsome spe- 

 cies, compact in growth, with ribbed pseudobulbs and light 

 green leaves; racemes long, springing from the base of the 

 bulbs, pendulous, and bearing a profusion of dark purple 

 flowers. It blooms during summer. Native of Trinidad. 



G. bufonia major. — Similar in habit of growth to the pre- 

 ceding ; indeed, they are mostly about the same size both in 

 pseudobulbs and leaves ; in this species, however, the flowers 

 difier considerably, being beautifully variegated with purple 

 and white. From Brazil. 



G. macidata. — This grows about eighteen inches high ; 

 pseudobulbs ribbed; leaves dark green; racemes upwards of a 

 foot in length, pendulous, and produced from the base of the 

 bulbs ; flowers very showy, yellow, spotted with rosy red. It 

 blooms in May. Native of Demerara. 



G. macidata alba. — A handsome and distinct form of the 

 preceding, which it very much resembles, but the pseudobulbs 

 are more deeply ribbed ; the flowers, which are pure white, 

 with a few spots of rose on the lip, are produced about the 

 month of May. Native of Guiana. 



G. portentosa. — This is a compact-growing species, not 

 diflfering greatly from the others in habit ; it produces an 

 abundance of its gay flowers from the base of the pseudo-
