different to that of most Orchids, render them more valuable. 

 The pseudobulbs are large, about eight inches high, with broad 

 flag-shaped leaves a foot or more long ; they all produce their 

 flowers, which are about twelve inches high, from the base of 

 the bulbs just as they begin to grow. All the kinds are best 

 grown in pots, with rough fibrous peat, good 'drainage, and 

 plenty of moisture at the roots in the growing season. The 

 cool-house is the most suitable place for them, as they succeed 

 best in a cool temperature. They ought to have a good season 

 of rest, and during this time they should be kept rather dry, 

 till they begin to show signs of growth. They are propagated 

 by dividing the bulbs just before they begin to grow. 



A. Clowesii. — A charming and free-growing species from 

 Columbia ; sepals and petals bright yellow ; lip pure white. 

 Blooms in June and July ; lasts long in perfection if kept in 

 a cool-house. There is a fine plant of this species in the rich 

 collection of T. Dawson, Esq., under the care of Mr. Anderson, 

 which produces in June as many as seventy-six expanded 

 flowers. It is a truly noble plant, and is worth a journey to 

 see when in flower. 



A. Clowesii macrantha. — A fine variety, also from Columbia, 

 growing about the same height as the preceding ; the flowers, 

 which are bright yellow, spotted with red, are produced in 

 July, and, if kept dry, continue three or four weeks in per- 

 fection. A scarce plant. 



A. ehurnea. — A magnificent species from New Grenada, 

 and consequently wiU make a valuable addition to the cool- 

 house. It has large dark coloured bulbs, with bright green 

 leaves, producing flowers as large as those of A. Clowesii, but 

 of the purest white, saving the lip, which is spotted with pink. 

 I have only seen this in bloom in Mr. Dawson's collection. 



A. Rucken. — A handsome Orchid from the same country 

 as the former, and flowering at the same time. The sepals
