V. CRISTATA, Lindl—A distinct and curiously marked Orchid. The stems 

 are erect free-growing, with distichous carinate leathery ligulate leaves, truncate 

 and three-toothed at the apex. The peduncles are short axillary erect, three- to 

 six-flowered, the oblong obtuse arching sepals and narrower petals of a yellow- 

 green, and the lip oblong, convex saccate towards the front, and divided at the 

 apex into three narrow diverging lobes, green beneath, the upper surface 



deep velvety tawny-yellow marked with 

 blood-purple longitudinal stripes, the 

 basal auricles ovate, of a deep blood- 

 purple on the inner face. It produces 

 its flowers from March to July, and lasts 

 in bloom for six weeks or two months. —

V. DENISONIANA, Benson et Bclxb. /. 

 • — A very chaste and desirable species, 

 the first white Vanda which has been 

 discovered. In its habit of growth it 

 much resembles V. Bensoni, but the 

 foliage is broader and somewhat longer. 

 Its stems are erect, with lorate rigid 

 recurved dark green leaves deeply two- 

 lobed at the apex, both the lobes being 

 sharp-pointed. The racemes are axillary, 

 five- to six-flowered, on stout ascending peduncles, while the flowers themselves 

 are medium-sized, thick and fleshy, the oblong spathulate dorsal sepal and the 

 broadly ovate lateral ones, as well as the spathulate petals, being white slightly 

 tinged with green, the lip being also white, pandurate, the apex two-lobed with 

 the lobes divaricate like the tip of a blackcock's tail, the base with two sub- 

 quadrate auricles, and the spur short and conical. — Arracan Mountains.
