covered inside with small purple spots ; the lip is white, with 

 purple blotches inside at the base. The flowers are produced 

 in May and June. Professor Reichenbach says this plant 

 may be a hybrid between A, unijJom and A. Clowesii ; it 

 resembles the latter in growth, and was introduced by us 

 along with it. — Colombia. 



A. eburnea, WUUams. — A magnificent species, which will 

 make a valuable addition to our cool-house Orchids. It has 

 large dark-coloured bulbs, with bright green leaves, a foot 

 and a half high, producing flowers as large as those of A, 

 Clowesii, but of the purest white, except the lip, which is 

 spotted with pink. This is a very rare plant. — Xeiv Grenada.

A. media, Rchb. f. — An interesting addition to the genus, 

 being a hybrid supposed to have been obtained by the crossing 

 of A. Clowesii and A. Faickeri. The sepals and petals are 

 orange yellow outside, brownish purple within, the lateral 

 sepals having a central line of orange, and much orange at 

 the base. The lip has the side lobes reddish brown, with the 

 disk ochre-coloured, and the anterior lobe short as in A. 

 Cloivesii. Raised by J. C. Bowi'ing, Esq., Windsor Forest. — 

 Garden hijhrid 



A. Ruckeri, Lindley. — A handsome Orchid of bold habit, 

 with large plicate leaves and rich dark flowers, of which the 

 sepals and petals have crimson spots on a yellow ground, and 

 the lip is deep crimson. It flowers in June and July, and 

 lasts two or three weeks in good condition. — Colombia.

A. Ruckeri retusa, Bchb. f. — A remarkable variety, with 

 the flowers lemon-yellow outside, covered with dark purple 

 blotches within ; the lip has its side lobes abrupt and 

 rectangular, and its middle lobe small, reflexed, and hairy. 

 — Colombia. 



A. Ruckeri sanguinea, Lindley. — This very fine variety is 

 precisely like the type in regard to its habit, but the flowers 

 are of a deep rich blood colour ; it is very rare in cultivation. 

 — Colombia.
