OECHID-GROWER S MANUAL. 



Culture. — The South African species, of which P. inthescens is an 

 example, grow well in the cool house, potted in peat and moss, and like 

 a good supply of water ; indeed, they should never be allowed to get dry. 



P. PUBESCENS, Bchh. f. — This beautiful dwarf-growing species, which 

 attains about 6 inches in height, has for a long time been in cultivation in our 

 gardens under the name of Epiphora puhescens. It has small pseudobulbs, 

 producing two or three leaves, which are dull green, oblong-linear, plane, and 

 slightly hairy beneath ; the floral racemes are erect, short and many-flowered, 

 the flowers being fragrant, of a rich bright golden yellow with a few purple 

 lines. It is an abundant bloomer, and is quite an exception to the majority of 

 the species in being very showy. Although introduced many years since, it is 

 still very rare. — Oaffraria ; Belagoa Bay.

Syn. — Epiphora jrubescens. 



PROMENAEA, Lindley. 



{Tribe Vandeae, swbtribe Cyrtopodieae.) 

 This is a small genus of pretty dwarf epiphytes growing about 

 3 inches high. They are pseudobulbous, with terminal leaves, and 

 produce their flower-scapes, which are drooping, from the base of the 

 pseudobulbs, so that they hang over the edge of the pot. The flowers 

 have spreading sepals, and a three-lobed lip crested in the middle. They 

 are not showy plants, but very curious, and hence deserve to be in 

 every collection. Some six or eight species, mostly Brazilian, are 

 referred to the group, which is by some authorities retained as a section 



of Zygopetalum. The column often bears on 

 its front a longitudinal elevated line or keel. 



Culture. — The Promenaeas are best grown 

 in pots with peat, the same treatment as that 

 recommended for PapJiinia being suitable 

 for them. 



PEOMENAEA CITBINA. 



P. CITRINA, Bon. — A neat and pretty dwarf- 

 growing epiphyte, with clustered small ovate 

 tetragonal diphyllous pseudobulbs, obloug-ligu- 

 lato pale green leaves, and deflexed scapes 2 to 3 inches long, bearing each a 

 comparatively showy deep rich yellow flower with a dark crimson blotch at the 

 base of the lip, which is obovate in the front part, with two oblong obtuse 

 erect basal lobes which are spotted with crimson ; they are produced at the end 

 of the summer, lasting in beauty for several weeks. — Brazil.
