0. rupestre, Lindley. — A very handsome cool house species, 

 of stout habit, with ovate compressed pale green smooth 

 pseudobulbs, dark green ligulate leaves a foot long and two 

 inches broad, and a stiff pyramidal panicle two feet high 

 bearing numerous flowers, which are large and showy, of a 

 brilliant golden yellow, the sepals and petals with about three 

 cinnamon blotches at the base of each, and the roundish 

 bilobed lip with a stain of the same colour across its base. — 

 Fera, on walls and rocks 



0. sanguineuni. — See Oncidium roseum. 



0. Sarcodes, Lindley. — A remarkably fine species, producing 

 its showy and handsome flowers during March and April. 

 The pseudobulbs are subcylindrical, from three to four inches 

 long, terminated by two or three broad lanceolate leaves, and 

 developing from the base a many-flowered panicle of large 

 and handsome flowers, of which the upper sepal is obovate, 

 yellow with dull brown cross-bars, the two lateral ones lance- 

 shaped and dull-coloured, the petals cuneate spathulate, the 

 basal two-thirds bright chestnut brown with a few yellow cross 

 lines, the apical portion yellow, and the broad repand undu- 

 lated lip clear yellow except a few red spots in front of the 

 crest. This showy plant has been scarce, but latterly there 

 have been some large importations, which have yielded many 

 varieties. It will do either in a basket or in a pot, with peat 

 and moss. — Brazil.

Si'N. — 0. Rigbyanum. 



0. serratum, Lindley. — A pretty species of very distinct 

 aspect, on account of its long straggling semiscandent panicles. 

 The pseudobulbs are oval, six inches high or more, bearing 

 large rigid lorate acute leaves a foot long, and the scape 

 twining and branched, from six to twelve feet long, bearing 

 many large flowers, which are bright chocolate brown mar- 

 gined with yellow. The sepals, as are all the parts of the 

 flower, are much crisped at the margins, the dorsal one reni- 

 form, and the lateral obovate, much lengthened out ; the petals 

 smaller, ovate acute, and connivent, the lip also small and 

 hastate. It should be grown in rough fibrous peat, and 

 placed in the cool house. — Peru.
