A charming, very sweet-scented little species, allied to the 
0. stramineum (Tab. 6254), but afar more elegant plant, with 
narrow leaves, an almost filiform scape, and brighter-coloured 
sparkling flowers. It was discovered by Warscewicz on the 
voleano of Chiriqui, at an elevation of 8000 feet, in New 
Grenada (near Panama) ; flowering in December, with the 
thermometer some few degrees above freezing point. It has 
been long cultivated on the continent, and first of all at 
Hamburgh, a town once so famous for the Orchid collections 
of its high office-bearer, as of Senator Janisch, and Consul 
Schiller ; and was soon thereafter introduced into England. 
It was flowered at Kew in December, 1872, from plants 
reared by Messrs. Veitch the previous year. 
Descr. Asmall species. Pseudobulbs aboutan inch long, orbi- 
cular or ellipsoid, much flattened, with sharp margins, smooth, 
finely wrinkled in age. Leaves three to six inches long, linear- 
lanceolate, acute, green, hardly narrowed into a petiole. Scape 
longer or shorter than the leaves, very slender, bearing an 
elongate, drooping, rather dense-flowered, contracted, sub- 
_ eylindric, very many-flowered panicle; branches short, slender,
