ONCIDIUM AMPLIATUM. 



THIS elegant species was discovered by 

 Cuming in 183 1-2 near the Gulf of 

 Nicoya, in Costa Rica, and introduced 

 by Mr. Richd. Harrison, of Liverpool, in 

 whose garden it flowered in March, 1835. It 

 was subsequently gathered by Mr. G. Ure 

 Skinner, Warscewicz, Purdie and other 

 collectors in various parts of Central America 

 from Guatemala to the Isthmus of Panama, 

 and whence it has since been frequently 

 imported. It has also been detected in 

 Trinidad, where herbarium specimens were 

 gathered by Dr. Bradford in 1 846 ; and in 

 Colombia by Burke, who saw it growing on 

 trees overhanging streams flowing into the 

 Magdalena at 500-1,000 feet elevation in 

 partial shade. 



This species is variable in the size of its 

 pseudo-bulbs, leaves and inflorescence, and 

 especially in the flowers, which sometimes 

 exceed i h inches in diameter, but are 

 frequently much less. The largest form, 

 known in gardens as ampliatum majus, is a 

 very handsome one on account of the singular 

 purity of the yellow of its labellum. The 

 usual flowering season is April and May. 

 The spikes generally attain a length of 

 3-4 feet, branched towards the extremity. 

 Sepals pale yellow blotched with red-brown ; 

 petals and labellum bright canary-yellow, 

 white behind ; crest thick, three-toothed, 

 white spotted with red ; column with a light 

 yellow apical toothed wing and a smaller one 

 on each side of the stigma.
