are white, produced about a dozen together in pendulous racemes during

A. CITRATUM, Thouars. — A beautiful and free-flowering dwarf species, 

 admirably adapted for basket culture. It has a very short stem, smooth, broad, 

 bright green, close-set oblong-lanceolate leaves, and slender pendulous racemes 

 of small but pretty flowers of a pale yellowish white, closely and evenly set in 

 two rows along the rachis. It is a compact-growing plant, and until within the 

 last few years was extremely rare. — Madagascar.

A. CRENATUM, Hchi.f. — This is a very rare plant, and quite distinct. The 

 flowers resemble those of A. Chailluanum in colonr and shape, but are much 

 smaller, as is also the growth of the plant; it flowers in June and July. — West 

 Africa. 



A. CRYPTODON, RcJib.f. — A distinct species, comparable in regard to habit 

 and foliage with A. GTiailluanum, and in its flowers, which are white and borne 

 in lax racemes, is equal to A. Ellisii. The latter have ligulate acute petals, a 

 lanceolate lip, and a filiform spur three times as long as the stalked ovaries, 

 which together with the base of the spur are reddish-white, the rest of the spur 

 being white. — Madagascar. 



A. DESCENDENS, Rchi. f. — A fine species which comes near A. Ellisii, but 

 differs in its oblong-ligulate leaves being obscurely bilobed at the apex, its 

 stronger spur which is more than four times longer than the pedicels, its cuneate 

 ovate acuminate lip, and its shorter hairy column. The flowers, which are 

 white, are produced on a drooping many-fiowered raceme. — Madagascar. 



A. EBURNEUM, Thouars. — A strong-growing free-flowering Orchid of noble 

 aspect, with densely packed, broadly ligulate obliquely bilobed distichous 

 leaves, which are eighteen inches long, leathery in texture, and of a light green 

 colour. The flowers, which have green sepals and petals and spur, and a broad 

 cordate cuspidate lip of ivory whiteness, are produced on upright racemes 

 eighteen inches long; it blooms during the winter months, and if kept free 

 from damp will last five or six weeks in perfection, on which account it becomes 

 very valuable. — Bourhon, Madagascar.

A. EBURNEUM SUPERBUM, Hort— A. fine variety of A. ehurneum, brought 

 home by the late Eev. W. Ellis, of Hoddesdon. . It is stronger in growth than 

 the type, and the flowers, which are ivory white, and very large, open about 

 the same time as those of.^. ebumeum, and continue a long time in beauty.— 

 Madagascar.
