LIST OF COOL OllCIIIDS. 105 



Lord Londesborougli's collection, under the care of Mr. 

 Denning, for the first time, I believe, in this country, although 

 it has long been introduced. The flower-spike was borne by 

 the third bulb back, not from the last made growth. This 

 plant bears very cool treatment, and is known in some 

 nurseries and gardens as O. candelabrum, and also, more 

 rarely, as 0. brevifolium. Grows well in peat and moss, in a 

 flat pan suspended near the light. Flowers from March to 

 May. 



0. Coradinci. — Professor Reichenbach thinks this may 

 possibly be a natural hybrid between O. triumphans — which 

 it much resembles — and one of the forms of which 0. odoratura 

 is considered the type. Sepals and petals from two to three 

 inches across, of a pale yellow colour, with two or three chest- 

 nut brown blotches ; lip creamy white, with a large irregular 

 blotch on its disc, and a few smaller spots near its base. The 

 crest of the lip is different from that of 0. triumphans, and 

 the habit and growth of this plant is more slender. It 

 appears to be a splendid thing, bearing two or three flowers 

 on a spike, but doubtless this number will soon be increased 

 as the plant gets distributed. 



0. cristatum (Peru). — This is not so pretty as some of the 

 other species. Its flowers are about two inches across, of a 

 greenish yellow colour, blotched with brown ; lip whitish 

 spotted with dingy brownish purple, with a radiating white 

 cres^t. It flowers freely and lasts a long time in bloom. 



0. crocidlpterum (New Granada). — A very pretty and free- 

 flowering species, somewhat resembling 0. naevium or its 

 congener 0. gloriosum in habit and mode of flowering. Its 

 pseudo-bulbs are compressed and conical, two-leaved; spikes 

 from twelve to eighteen inches long, bearing numerous pale 

 yellow flowers spotted with brown ; individual flowers two or 

 three inches across. Its blossoms are delicately scented, like
