three-toothed in front. The plant is very much like S. Sleelii, only the flowers ' 

 of S. Hadivenii are more erect, and the scape is an inch or two higher.— Bra;; iZ.

S. KEYSERIANA, Hort. — This species was exhibited by Messrs. P. Sander & 

 Co. before the Eoyal Horticultural Society in May, 1888. It is dedicated to 

 Sir Polydore de Keyser, and resembles 8. Slcelei in habit. The leaves are 

 cylindrical pendulous, and several feet in length ; flowers fleshy, broad ; sepals 

 and petals yellow, heavily spotted with purple-maroon; lip broad, open, and 

 streaked with purple-maroon on a lighter ground. — Rorahna, Ottiana.

S. STEELII, Lindl. — A handsome epiphytal plant of peculiar habit. The 

 branching rhizome, which is ebulbous, bears on each branch a solitary terete 

 channelled flagelliform leaf as thick as a swan's quill and 2 to 4 feet long, 

 tapering to a fine point ; the scape is one- to three-flowered, the flowers large, 

 fragrant, pale primrose-yellow blotched with reddish-brown, and the lip is 

 three-lobed, pale yellow, striately marked with brownish-crimson, especially on 

 the lateral lobes, the crest being oblong with three orange-coloured teeth in 

 front. It produces its blossoms at diflferent times of the year, lasting a long 

 time in perfection. — British Guiana.

SOBBiALIA, JRidz et Pavon. 

 (_Trihc- Ncottieae suitriie VaDilleae.) 

 This genus contains some very handsome species which are quite 

 distinct from most other Orchids in liabit and general aspect. They are 

 all strong free-growing terrestrial plants, the long slender reed-like stems 

 furnished with dark green plaited sheathing leaves, and bearing at their 

 summit large showy flowers, as many as six or more being produced from 

 a single stem, but rarely having more than one expanded at one time. 

 The blossoms in most of the species are verj- large and brilliantly-coloured ; 

 and, although individually the\- last but a short time, this is compensated 

 for by the quick succession of new flowers, for as soon as one decays 

 another appears. The sepals are sub-equal, erect, connate at the base, 

 the petals similar or broader, the lip erect from the base of the column, 

 around which its lateral lobes are folded, the limb concave, undulated or 

 fimbriate, undivided or two-lobed, and the column elongate and sub- 

 incurved. There are about thirt}- species, found in the Andes of 

 Tropical America, from Peru to Mexico.
