B.Sherrattiana, Bateman. — A charming species, resembling 

 B. patula in habit. It has flattened corm-like pseudobulbs, 

 plicate lanceolate acuminate leaves, and erect scapes three 

 feet high, bearing a raceme of large showy flowers of a bright 

 rose-colour ; the lip, which is three-lobed, with the lateral lobes 

 rounded and flat, and the middle one smaller and reniform, 

 is of a deeper rosy purple with three orange-coloured lamellae 

 down the white centre. It is a most desirable acquisition 

 to the terrestrial section of Orchids. When growing, it 

 should be kept in the cool-house. — New Grenada.

BOLLEA, Reichenhacli Jll. 

 {Tribe Vandese, subtribe Cyrtopodiese.) 



In their manner of growth the species of Bollea are much 

 like those of Pescatoria, but the flowers are quite different. 

 Both Keichenbach and Bentham and Hooker regard the 

 group as a section of Zygopetalum., Their chief peculiarities 

 consist in their one-flowered scapes, their broad sepals and 

 petals, their ample rounded shortly clawed lip, which has a 

 prominent crest on the disk, and their short thick column, 

 which has the anther-bed entire and subcucullate. The 

 species are not numerous, and all inhabit Tropical America. 



Culture. — These plants succeed well in the warm-house in 

 a mixture of peat and moss, and they require a good supply of 

 water during the time of growth. Many persons cultivate 

 them in pots, but we have found them do well on blocks, 

 especially those formed of fern stems, but treated in this way 

 they require an abundant supply of water when growing. 



B. COelestis, Bchh. f. — In growth this species resembles 

 B. LaJindei, but the colouring of the flower is altogether 

 brighter and more distinct. The leaves are close-set, dis- 

 tichous, and cuneate-oblong ; the scapes fifteen to eighteen 

 inches high ; the flowers large, three to four inches across, 

 the oblong acute sepals and the shorter petals light blue at 

 the base, deeper mauve in the middle, the marginal tips 

 white ; the lip is deep violet in front, the prominent basal
