ONCIDIUM. 233 



0. Limminghei. — This species is perhaps the most singular 

 in the whole genus ; the habit is similar to that of a 

 Sophronites ; the leaves are dark green, arranged in a dis- 

 tichous manner, and netted with veins of bright brown ; the 

 flowers are golden yellow, richly spotted with brown. It 

 succeeds admirably in a somewhat cool temperature. Native 

 of BrazU. 



0. longipes. — A beautiful compact small species from Rio 

 Janeiro, growing about six inches high, and producing spikes 

 of flowers in great abundance ; lip large and of a bright golden 

 yellow ; petals brown, tipped with yellow. It blooms during 

 the summer months, and will do well on a block. 



0. luridum Dodgsoni. — A splendid variety, which I have 

 only seen in the choice collection of R. B. Dodgson, Esq., at 

 Blackburn, Lancashire. The leaves are very thick and fleshy, 

 in the way of Imidum, but broader and longer, producing 

 flower spikes seven feet long, and much branched, bearing 

 between three and four hundred flowers on each ; colour 

 orange and yeUow, barred with dark brown. Under the care 

 of Mr. Whitehead this has become a splendid specimen, potted 

 in peat and sphagnum moss, and treated with a liberal supply 

 of both heat and moisture. Native of the West Indies. 



0. luridum guttatum. — A fine variety from Jamaica : it 

 produces long spikes of flowers, which ai'e yellow, brown, and 

 red in colour ; it blooms during the summer months : con- 

 tinues in perfection a long time, and is best grown in a pot 

 with peat. 



0. macranthum. — This splendid plant was introduced by 

 the Messrs. Backhouse, of York. It is robust in growth, with 

 large pseudobulbs and dark green leaves ; spike several feet 

 long, twining, branching, and many -flowered ; flowers from 

 three to four inches across ; sepals and petals very round and 

 broad, thick and fleshy, rich yellow, tinged with purplish
