LIST OF COOL ORCHIDS. 121 



lip fiddle-shaped, pure white blotched with purple, like the 

 petals, and having a bright lemon-yellow crest. It is a most 

 beautiful and free- flowering plant, lasting from four to five 

 weeks in beauty. Grows well in peat, or on a block, with 

 living sphagnum, in the cool end of the house. 



*0. sat codes (Peru). A plant having narrow bulbs, from 

 five to seven inches high, bearing two oblong leaves of the 

 darkest green ; flower- spike from two to five feet long, bearing 

 from sixty to seventy golden -yellow flowers from one to one 

 and a half inch across, heavily blotched with crimson brown. 

 It is one of the most distinct and beautiful Oncids in cultiva-

 with the dingy-flowered 0. pubes a species scarcely worth a 

 place in collections. 



0. serratum (Peru). This species slightly resembles the 

 grand 0. macranthum in habit, its ovoid pseudo-bulbs bearing 

 two ensiform leaves from one to two feet long ; flower spike 

 from five to twelve feet long, branched and flexuose like that 

 of 0. macranthum ; flowers from two to three inches across, of 

 a deep brown colour, very peculiar, on account of the crested 

 apices of the petals being connate, forming an arch over the 

 small lip and the column. Grows and flowers well in the cool 

 house, treated like macranthum. 



*0. splendidum (Guatemala). A robust species, having the 

 habit of 0. microchilum, but bearing flowers superior to it in 

 size and beauty. Bulbs an inch high, bearing a solitary oblong 

 leaf, from four to seven inches long, and of great substance ; 

 flower-spike erect ; flowers two inches across ; sepals and 

 petals green, heavily barred with brown ; lip of a rich and 

 bright golden yellow colour. It is one of the finest species in 

 cultivation. 



*0. tigrinum (Mexico). Also known in many collections as 

 O. Barkeri. It is a very beautiful and showy species ; sepals
