ONCIDIUM. 251 



supporting a pair of short coriaceous leaves ; the spike is 

 long, producing many large flowers ; sepals and petals a 

 rich coppery colour ; lip the same colour, with lighter spots 

 in the centre. This blooms at different times of the year, 

 and lasts three or four weeks in beauty. It requires to be 

 grown on a block of wood in the CattJeya house, and should 

 never be allowed to get dry, for it seems to like plenty of 

 moisture. Native of the Organ Mountains in Brazil. 



O. crispum grandifioram. — A very fine variety of the pre- 

 ceding. Its blossoms are very large, twice the size of those 

 of 0. crupum, and deep rich brown in colour. It succeeds 

 best on a block, and requires a good supply of water at the 

 roots. 



(). crispum marffinatum — The flowers of this variety are 

 scarcely so large as those of the preceding one ; they are, 

 however, superior in size to, and richer in colour than, those 

 of 0. crispum, and, in addition, the sepals and petals are 

 broadly margined with golden yellow, which affords a striking 

 and beautiful contrast with the rich chocolate ground colour. 



0. Crccsus. — A pretty, dwarf-growing plant ; its pseudo- 

 bulbs are slender, tapering upwards, supporting a pair of 

 light green leaves ; spikes short, few flowered ; sepals and 

 petals greenish yellow, tinged with brown ; lip large, ricli 

 golden yellow, the crest prominent, and deep velvety black.. 

 It blooms very freely during summer, and continues a con- 

 siderable time in full beauty. The plant succeeds best in 

 the Catthya house, either suspended from the roof upon a 

 block, or potted in peat and sphagnum moss. Native of 

 Brazil. 



0. cruentum. — A very desirable species ; pseudobulbs very 

 dark green ; leaves long lanceolate ; it produces fine branch- 

 ing spikes of yellow flowers ; sepals and petals yellow, barred 

 with brown ; lip pale yellow.
