_. A very curious discovery of Col. Benson’s, in Rangoon or 
_ Arrakan, and by him communicated to Messrs. Veitch, who 
flowered it in November, 1868; it is nearly allied to S. den- 
_ ticulatum (Tab. nost. 4772), of the Khasia Mountains, and to 
S. acutifolium, Lindl. of the Sikkim Himalayah ; having a 
similar habit, subcorymbose inflorescence, spathulate petals and 
sepals, and large broad laterally compressed spur, upon the 
outer edges of which the very broadly triangular lip is 
perched ; but it differs from these in the colour of the flower, 
the naked disc of the lip, the shorter stem, and bifid apices 
of the leaves. | 
_ Desor. A small epiphyte. Roofs flattened, creeping ex- 
tensively on the surface of wood, pale brown. Slem very

green, paler and keeled below, coriaceous. Peduncle one to

very short, almost corymbiform, drooping, many-flowered, 
shorter than the leaves. Mowers, twelve to fifteen in each 
corymb, two to three inches in diameter, pale yellow with 
faint red markings on the edge of the spur. Svya/s and petals
