0. cmpiim marginatum. — 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. cnspwn, 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. Croesus. — A charming 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, rich 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 

 Cattleya 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 branching 

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

 brown ; lip pale yellow. 



0. cucullatum. — Although this is a small-flowered species, 

 it is a very beautiful one. It is a dwarf-growing plant, and the 

 flowers (which are in the sepals and petals rose colour, and in 

 the lip reddish purple, spotted with deep purple) last a long 

 time in perfection. Found in New Grenada at 8,000 feet 

 altitude. 



0. cucullatum flavidum. — Similar in habit to the species ; 

 sepals and petals yellow, blotched with brown; lip purple, 

 margined with white. This is a distinct and very desirable 

 form of this plant ; it must be placed in the coolest house ; 

 the flowers are produced in spring, and continue a long time 

 in beauty. 



0. cucullatum macrochilum. — An entirely difierent-looking 

 plant from the previous one. It grows about a foot high, pro-
