HOULLETIA, Brongniart. 



(_Tribii Vandeae, snbtribe Stanhopieae.) 

 A small group of epiphytes, with large loosely racemose flsWfefs,- 

 well worth cultivating on account of their distinctness, though the^' 

 have been somewhat neglected by orchidologists. They have free" 

 spreading sub-equal 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 bi-auriculate at the baseV 

 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 Colombia. 



Culture. — ^The Houlletias grow best in pote, 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. BROCKLEHURSTIANA, Lindl. — ^A handsome, showy, and distinct species',-- 

 which grows 2 feet or more high, and has conical furrowed pseudobulbs, andt 

 broadly lanceolate pale green leaves on long petioles ; the flower scapes are stouts- 

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

 individual flowers very fragrant, half -nodding, and measuring 3| 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 

 lobes linear-lanceolate reflexed, and the middle lobe (epichil) ovately triangular, 

 somewhat hastate, the lateral lobes being acuminate. The flowers as figured in 

 Faxton's Magazine are of a much darker brown, and the lip whitish striped and 

 spotted with purple. — Brazil.
