Barkeria.—The Barkerias form a section of Epiden- 
drums. They should be grown in baskets or suspending 
pans in the cool intermediate house. They require a dry 
and cool resting period. 
Bartholina.— The Bartholinas are dwarf, terrestrial 
Orchids of South Africa. They should be potted in loam, 
peat, and sand, and cultivated on a green-house shelf. Rest 
dry and cool. B. pectinata is the only species in gardens, 
Batemannia and Bollea. See Zygopetalum. 
Bifrenaria.—Pot these as recommended for epiphytal 
Orchids, and grow them in the intermediate house. B. 
Harrisonie is the finest species. Others worthy of cul-

B. tyrianthina, and B. vitellina.

The most familiar species are B. brachiata, B. caudata, 
B. Lawrenceana, and B. verrucosa. 
Broughtonia.—B. sanguinea is a pretty, crimson-flowered 
species from Jamaica. B. lilacina is also a fine species, 
though rarely seen in gardens. Broughtonias should be 
grown on bare rafts suspended in the warm or intermediate 
house. 
Brassavola._A small genus with white, fragrant 
flowers, B. Digbyana,a species with large, fringed-lipped 
flowers, has been much used by the hybridist. Brassavolas 
may be grown with the Cattleyas. 
Bulbophyllum.—A widely distributed genus which may

should not be strictly dried off. All the species thrive in
