gardener to Lord Londesborough, in 1870, and also again 

 with Mr. Whitehead, gardener to R. B. Dodgson, Esq., of 

 Blackburn. A very rare species. 



0. Sjirucd. — This species in habit somewhat resembles 

 O. Ceholetta, but its terete leaves are more swollen in the 

 centre ; it produces its bright yellow flowers in great profusion, 

 and from its distinct habit is a good addition to a collection. 

 Native of South America. 



0. steUif/erum. — This is a very distinct and free-flowering 

 species, aUied to 0. Jiastatum ; flowers panicled yellowish, 

 with brown dots ; the lip is yellowish white, with a darker 

 callus. Native of Mexico. 



0. suj^erhiens, also known as O.cBmulum. — This plant belongs 

 to the 0. serration section ; the pseudobulbs are similar to 

 0. serratum, and about four inches long, and somewhat ovate ; 

 leaves about a foot long, narrow, and dark green, panicle two 

 to three feet long, bearing twenty to thirty flowers, which are 

 two inches and a half in diameter ; sepals chocolate brown, 

 tipped with yellow ; petals yellow, barred with chocolate ; lip 

 small, reddish brown, with yellow crest. New Grenada. 



0. tifjriniim. — A remarkably handsome dwarf Orchid from 

 Mexico ; the flowers are very large ; the sepals and petals 

 rich brown, barred with yellow ; the lip a bright yellow, 

 about an inch and a half across. It produces its branching 

 spikes of flower during the dull months of autumn and 

 winter, which greatly enhances its value, and it lasts six 

 weeks in bloom. There have been several importations during 

 the last three years, which has made this fine Orchid more 

 plentiful. This species is sometimes found under the name 

 of Q. Barkeri, but it is undoubtedly the same thing. 



0. trilingue. — A very distinct and peculiar plant, still very 

 rare in collections ; it very much resembles 0. serratum, to 

 which, indeed, it is nearly allied. Sepals and petals rich
