PROMENJEA. 253 



P. pubescem. — This beautiful dwarf-gi-owing species has 

 for a long time been in cultivation in our gardens under the 

 name of Epiphora pubescens. It has small pseudobulbs, pro- 

 ducing two or three leaves, which are narrow, dull green, 

 and slightly hairy beneath ; raceme erect, short and many- 

 flowered ; flowers rich bright golden yellow, with a few purple 

 lines. This plant grows well in the cool-house, potted in 

 peat and moss, and likes a good supply of water — indeed, 

 it should never be allowed to get dry. It is an abundant 

 bloomer, and is quite an exception to the majority of Polys- 

 tachyas in being very showy. Although introduced many 

 years ago, it is still very rare. Native of Algoa Bay. 



Promen^a. 



This is a small genus of pretty little dwarf-growing 

 Orchids, about three inches high : they produce their flowers 

 from the base of their pseudobulbs, which are drooping, and 

 hang over the edge of the pot. They are not very showy 

 plants, but very curious, and deserve to be in every collec- 

 tion. They axe best grown in pots with peat, the same treat- 

 ment as that recommended for PapAmia cristata being suitable 

 for them. 



P. citrina. — This is a native of Brazil, and produces its 

 flowers, which are deep rich yellow, spotted with dark 

 crimson at the base of the lip, at the end of summer, lasting 

 in beauty for several weeks. 



P. Rollwsoni.— This species also produces its pale yellow 

 flowers during the autumn, lasting three weeks or more in 

 beauty. Native of Brazil. 



P. stapelicddeB.— In this the pseudobulbs are small and 

 nearly round, bearing a pair of thin light green leaves. The 

 colour of the sepals and petals is greenish yellow, spotted 

 and barred with dark purple; the lip is deep purple.
