ONCIDIUM. 



628 



broad, of a bright green on the upper surface, paler beneath. The flowers are 

 very numerous, in ample much-branched, panicles, and are individually large — 

 2| inches across the spreading petals, and brilliantly coloured; the sepals are 

 small, the dorsal one concave obovate, yellow banded with purple, the lateral 

 ones oblong, connate at the base ; 

 the petals are an inch long, 

 clawed, broadly fiddle-shaped, the 

 margin undulated, the apex two- 

 lobed, the colour deep golden 

 yellow, with a series of large 

 unequal irregular chestnut-brown 

 blotches along the centre; and 

 the lip is very large, contracted 

 behind into an auricled claw 

 spotted with orange-red, and 

 having a tubercled beaked callus, 

 the broad oblong front portion 

 bright yellow and deeply bilobed. 

 There have been some fine varie- 

 ties of this species bloomed of 

 late years, and we are glad to say 

 there have been some good impor- 

 tations of it. As an exhibition 

 plant this is one of the most 

 telling that can be staged, the 

 rich golden yellow of its blossoms 

 contrasting well with the varied 

 hues of other Orchids. It is best grown in the cool house, in a basket or on a 

 block, as fully exposed to the light as possible. It blooms in April and May. — 

 Brazil.
