ORCHID-GROWER'S MANUAL. 



sepals and petals ; the colour pure white, with a prominent blotch of yellow 

 on the crests of the lip. It blossoms in February and March, and will con- 

 tinue in perfection four or five weeks if the flowers are kept free from damp. 

 This plant, which is largely grown for out flowers, is the finest of the genus, 

 and in fact one of the finest of all Orchids, and ought to be in every collection. 

 We have seen on a specimen grown in the collection of J. Buchanan, Esq., 



Edinburgh, as many 

 as 600 flowers at one 

 time; and on another, 

 grown by Mr. Cross, 

 at Melchet Court, 

 seventy-five spikes 

 are recorded as being 

 produced, the speci- 

 men measuring 5 

 feet across. We find 

 it makes its growth 

 best in the cool- 

 house, but after this 

 is completed we place 

 the plants in the 

 Cattleya house, as if 

 left in the cool the 

 flower spikes are apt 

 to damp and turn 

 black. Chatsworih va- 

 riety produces . more 

 flowers on the spike 

 than the normal form ; they are also larger and are produced later in the 

 season. Trentham variety is the latest flowering form, blooming several weeks 

 after the others are over. — North India.

C. CRISTATA ALBA, Moore. — This fine novelty is in all respects similar to 

 the type, except that instead of having the yellow blotch on the lip, its flowers 

 are everywhere of a pure white. It blooms during winter and spring, and lasts 

 from two to three weeks in perfection. — India.

C. CRISTATA CITRINA, Williams. — This is a very distinct variety, which 

 invariably flowers some two or three weeks later than the type, which is a 

 decided advantage, as it prolongs the flowering season, and it also differs in 

 having the centre of the lip stained a delicate lemon-colour, and not deep yellow 

 as in the ordinary form of the species. Bar/a variety is intermediate between
