0. luteo-purpureum.. — The numerous varieties of this plant 

 have given rise to many names, but I think most growers 

 of Orchids are now satisfied they are only varieties ; still, as 

 such, they are well worthy of a place in every collection. 

 The leaves are about a foot long ; flower spikes about ten 

 to eighteen inches ; sepals and petals of a bright brown, the 

 margins yellow ; lip white, with the base brown, and banded 

 with white, the bristles or beard of the lip being deep yellow. 

 It is a native of New Grenada, being found at an altitude of 

 7,000 to 8,000 feet. 



0. maculatum. — A pretty species from Guatemala. It grows 

 a foot high, with short thick pseudobulbs, and produces its 

 sub-erect spikes of blossoms during winter ; colour yellow, 

 crimson, and dark rose ; it will last in bloom a long time, 

 and succeeds best in a cool-house, in a pot, in peat and moss. 



0. maculatum integrate. — A very interesting variety of the 

 preceding which I had the good fortune to introduce. It has 

 been named by Professor Reichenbach, who, it appears, knew 

 it already in a dried state. Growth the same as maculatum. 

 Sepals light brown ; petals white, with a few transverse bars 

 of brown at the base ; lip white, with a yellow crest. Native 

 of Guatemala. 



0. memhranaceimi. — A beautiful small-growing species, from 

 Guatemala ; sepals and petals pure white ; the lip of the same 

 colour, barred with brown. It blooms during the winter 

 months, and continues in bloom four weeks. This will do on 

 a block of wood or in a pot. There are many varieties of this 

 species. 



0. memhranaceum roseum. — A handsome variety, producing 

 its flowers through autumn and winter ; they are rose colour, 

 shaded with yellow, barred with brown, and produced five or 

 six on a spike. Native of Guatemala. 



0. ncEvium. — A pretty dwarf Orchid from Truxillo. The
