the column, whilst the front portion is spreading, and un- 
dulated or fringed. All the species are natives of tropical 
America. 
Culture——The subjoined species, when in good health, 
are most successfully grown in the intermediate house ; 
but newly-imported plants should be placed in a stove for 
the first year or so until they have become established. 
Growing freely, and being somewhat gross feeders, they 
should be given pots large enough to allow the roots free 
play. The compost should consist of lumps of good, 
fibrous peat, mixed with a small proportion of lumpy 
charcoal. As Sobralias require almost unlimited supplies 
of water during growth, careful drainage is important, a 
depth of about one-fifth of the pot being necessary. During 
winter less water is required, but the soil should always 
be moist. When the growths become crowded, it is 
advisable to remove a proportion of those that have flowered, 
thus giving light and freedom to the young ones that are 
pushing. 
S. leucoxantha.—A superb species of recent introduction, 
and as yet rare in gardens. Its slender stems are i}ft. to 
2ft. high, and produce the blooms at intervals during the 
summer months. The leaves are plaited, cuneate-oblong, 
and pointed. The sepals are nearly 3in. long by tin. broad, 
pure white, the tips recurved; the petals are also pure 
white, scarcely so firm in texture as the sepals. The 
outside of the lip is pure white, as is also the prettily- 
frilled edge on the inside, but the colour deepens gradually 
into a rich golden yellow in the throat; the sides are 
incurved over the column, forming a tube 2in. in length, 
the apex expanding. A native of Costa Rica; introduced 
in 1885.
