brown ; lip hastate, much smaller, yellow, the side lobes being 

 dark purplish brown. It is perhaps the grandest Oncidium 

 yet introduced ; the cool-house suits it best, and it should be 

 potted in peat and sphagnum moss, with good drainage. It 

 blooms during spring and early summer; lasts long in full 

 beauty. This plant was first exhibited from the fine collection 

 of Lord Londesborough. It is beautifully figured in the 

 second series of Warner's " Select Orchidaceous Plants.'' 

 Native of New Grenada. 



0. Marshallianum. — This lovely plant is a native of South 

 America; it is a near ally of 0. crispum. The flowers are

 marked with violet or purple ; but in the manner of its mark-

O. ohlongatum. — A handsome free-flowering species, from 

 Guatemala, compact in habit, with short thick pseudobulbs ; 

 foUage light green, about twelve inches in length ; flowers very 

 showy, of a bright yellow, and of good size ; blossoms during 

 the winter months, and continues a long time in perfection ; 

 it succeeds best in a pot. 



0. obryzatum. — Of nice compact habit, growing freely in the 

 cool-house ; producing in great abundance its fine branched 

 spikes of bright yellow flowers, barred with brown, and which
