HOULLETIA, Bronrjniart. 

 {Tribe Vandese, suhirihe Stanhopiefe.) 



A small group of epiphytes, with large loosely racemose 

 flowers, well worth cultivating on account of their distinctness, 

 though they have been somewhat neglected by orchidologists. 

 They have free spreading subequal sepals, and a narrow 

 fleshy lip continuous with the column, the base hollowed or 

 two-lipped, and the lateral lobes produced behind into 

 retrorse curved horn-like processes, the broadish middle lobe 

 articulated and undivided, often truncate or biauriculate at 

 the base. They have one-leaved pseudobulbs, broad long- 

 stalked plicately-venose leaves, and erect scapes rising from 

 the base of the pseudobulbs. There are five species known, 

 natives of Brazil and Columbia. 



Culture. — The HouUetias grow best in pots, in peat with 

 good drainage, and like a liberal supply of water during the 

 growing season ; they do well in the cool Odontoglossum 

 house. Propagation is effected by separating the pseudobulbs 

 just before they begin to grow. 



H. Brocklelmrstiaiia, Lindley. — A handsome, showy, and 

 distinct species, which grows two feet or more high, and has 

 conical furrowed pseudobulbs, and broadly lanceolate pale 

 green leaves on long petioles. The flower scapes are stout, 

 produced from the base of the bulbs, and are erect, ten to 

 twelve-flowered, the individual flowers very fragrant, half- 

 nodding, and measuring three and a half inches or more in 

 diameter ; the sepals are oblong, concave, and together with 

 the spathulate petals are of a rich sienna -brown, spotted 

 thickly with dark purple-brown, and the lip is yellow, more 

 finely and thickly spotted with dark purple-brown, its side
