treatment. It is very nearly allied to 0. ReichenJieimii, and 

 may probably prove to be a variety of that species. Being a 

 very abundant bloomer, it will no doubt become generally 

 cultivated. 



0. lAndleyanum acumenata. — A very large flower ; sepals 

 and petals equal about an inch and a half long, canary yellow 

 blotched with dull cinnamon, column and base of lip very 

 long and prominent, pure white ; the two teeth white, and very 

 long ; front of lip has tall acuminate, tapering to quite a sharp 

 point nearly an inch long, and dull cinnamon. 



0. luteo-purpiireum. — 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

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

 7,000 to 8,000 feet. 



0. luieo-purjmreum sceptrum. — Sepals larger than the 

 petals, deep chocolate brown streaked and margined with 

 yellow ; petals irregularly lobed at the edges, yellow blotched, 

 same colour as the sepals ; lip yellow with serrated edge 

 dotted and blotched with chocolate. Native of New Grenada. 



0. macidatum. — 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 integrale. — A very interesting variety of the 

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

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