of a dark green colour, -while in others they are of a lighter 

 shade. The flowers grow in drooping racemes, which some- 

 times attain a length of three feet, and are often branched ; 

 the flowers are unusually large, white beautifully mottled with 

 clear bright rose colour, and have a rich rose-coloured lip ; 

 they are produced during May, June, and July, and continue 

 for three or four weeks. This makes a fine exhibition plant, 

 and Prof. Morren well observes, " I'inflorescence rameuse est 

 toujours somptueuse." — India: Sikkim, Assam, dr.

A. Houlletianuin, Rchh.f. — This most distinct and beau- 

 tiful species was exhibited by Sir T. Lawrence, Bart., M.P., 

 in 1876, when it was certificated by the Royal Horticultural 

 Society ; previous to this it had been flowered by Mr, 

 Liiddemann, of Paris. The growth, including roots, foliage, 

 and habit, resembles that of A. virens, the leaves being short, 

 lorate, and bluntly two-lobed at the apex. The flowers, 

 which are large and borne on dense many-flowered racemes, 

 resemble in form those of A. falcatum, but the sepals and 

 petals are bufi"-coloured tipped with a single spot of magenta, 

 and the lip is creamy-white with a wedge-shaped blotch of 

 magenta on the anterior part of the subrhomboid fimbriated 

 middle lobe, and bearing lines of the same colour on the 

 semifalcate side lobes. It flowers in May and June. — Cochin

A. illustre, Rckh. f. — This is, according to Prof. Reichen- 

 bach, a grand plant, imported with A. crisjmm, and sup- 

 posed to be a natural hybrid. It has very short broad leaves 

 marked with a few dark spots, and unbranched racemes of 

 flowers in the way of A. macxdosum, but larger, the sepals 

 and petals being broader, with a lilac hue over the white and 

 with very few blotches, and these mostly on the inner side 

 of the petals ; the lip is very fine, rich amethyst-purple, 

 with the longitudinal basal markings characteristic of A.
