ONCIDIUM INTERMEDIUM. 



of a dull brownish orange, spotted with, rich brown; lateral lobes of the lip rolled back, and 

 forming two horn-like tubes ; crest posteriorly with two thick tuberculated lobes, the interior 

 portions of which are yellow, the exterior white, between which arises a sharp, elevated, callous 

 ridge, yellow at its commencement, and white at its termination in the claw of the lip, on each 

 side of which is a white diverging fleshy auricle ; pollen-masses sulcated posteriorly, fixed upon 

 the lunated margin of a broad caudicula, the horns of which lie in contact with them ; the lower 

 portion is ventricose, and embraces the anterior half of a thick, round, compressed gland ; wings 

 of the column white. 



For an opportunity of figuring this magnificent epiphyte we are indebted 

 to George Barker, Esq., of Springfield, near Birmingham, in whose stove it 

 flowered in March last. It is a native of Cuba, from whence it was sent to Mr. 

 Barker by Don Domingo de Goicouria, a merchant of Havannah. 



It is closely allied both to O. carthaginense, and 0. luridum, but appears to us 

 to be sufficiently distinct from each of those species. It approaches carthaginense 

 in the cochleate form of the upper sepal, in the arrangement of the anterior 

 portion of the crest, and in the sinuous, oblique wings of the column. It differs 

 from that species in the shape of the lateral sepals, which are obtuse (not acute), 

 as well as of the petals, which are entire (not lobed), and in the lateral lobes 

 of the lip, which are rounded and revolute (not acute and recurved). On the 

 other hand, it resembles luridum in its very obtuse petals, and in the dwarf 

 lateral lobes of the lip ; while it differs from it in the obtuse (not acute) lower 

 sepals, in the completely revolute lobes of the lip, in the shape and colour of the 

 tubercles of the crest, and in the much brighter colour and more distinct mark- 

 ings of the flowers. Its leaves, also, are not so thick and fleshy, and by no 

 means so strongly and prominently keeled as are those of luridum. 



It forms a most conspicuous ornament in the stove, and requires the treat- 

 ment usually adopted with other tropical orchidacese, viz., to be kept in a warm, 

 moist stove when growing, but more cool and dry when in the dormant state.
