by the separation of Lycaste, Colax, Promencea, Bifrmaria, 

 and others, though still containing numerous species. 



Culture. — These plants are all of evergreen habit, and can 

 be grown in the cool house with Odontoglossums. They 

 succeed best grown in pots, in a mixture of peat and moss, 

 and require a liberal supply of water during their growing 

 season, the amount being reduced during the period of rest, 

 when only just sufficient to keep them in a plump state should 

 be given them. 



M. grandiflora, Lindley. — A handsome species, with the 

 aspect of a Lycaste. The pseudobulbs are depressed ovate, 

 two-edged, and of a deep green colour ; the erect ovate- 

 oblong leaves are also dark green, and about a foot long ; 

 and the flowers are produced singly on bracteate scapes about 

 six inches in length ; the lateral sepals having a spread of 

 about three and a half inches. The oblong-acute sepals and 

 shorter petals are pure white, the lip pouched, dark purple at 

 the sides, the triangular middle lobe yellow in front, white 

 towards the base. A very desirable plant, blooming during 

 autumn, the flowers deliciously fragrant. This fine plant 

 enjoys a very cool atmosphere ; indeed, to succeed with it, 

 the coolest end of the Odontoglossuin house should be selected 

 for its reception, and the atmosphere kept very moist. —

M. luteo-alba, Lindley. — This is a very striking plant when 

 in blossom, both on account of the peculiar tawny colour 

 and the triangular form of its flowers. The pseudobulbs are 

 ovate compressed, something like those of M. venusta, and 

 the solitary leaves are long and broad, and grow to the height 

 of eighteen inches. The large flowers, which are developed 

 at di0"erent times of the year, proceed from the side of the 

 bulbs, and have three linear-oblong sepals three inches long, 

 of a tawny yellow in the upper two-thirds, creamy white in 

 the lower portion, and brownish externally, the three spread- 

 ing out triangle-wise, and the two lower ones being twisted ; 

 the petals are about half as long as the sepals, white at the
