Oncidium. 



O. fuscatum {JichlKf.). — A synonym o'i Mll/oiiia JVarscawiizii. 



O. haematochilum {Lindl.). — A large-leaved, bulbless species, 

 with an erect spike of brightly-coloured flowers. It is closely 

 related to O. Laiiccatnim, and is almost as ornamental as that 

 species. The leaves are oblong, flat, thick, stiff, 6in. to gin. 

 long, about 2in. broad, dark green, with dull brown spots. The 

 flower-spike is erect, compact, it't. to 2ft. long, and bears from 

 ten to thirty flowers, each i^in. across ; sepals and petals equal, 

 nearly lin. long, spathulate, wavy, greenish-yellow, with spots 

 of rich cinnamon : lip narrow at the base, and eared, the front 

 part spreading, oval, ;Jin. wide, undulated, with a hump-like crest ; 

 colour bright crimson, with marginal spots of a deeper colour. 

 This distinct plant requires the same treatment as is recommended 

 for O. Lanceaiium. It blossoms in November. A native of 

 Trinidad, and introduced in 1S47. (W. O. A., i., t. 32.) 



O. incurvum {Barker). — A distinct and pretty-flowered plant, 

 of easy culture. It is one of the best of the smaller-flowered 

 species. The habit is similar to that of O. ornithorhyiichuiii, 

 but more robust. The pseudo-bulbs are ovate, compressed, 

 furrowed, 2in. long, two-leaved. The leaves are ensiform, about 

 9in. long, acute-pointed, dark green. The flower-spikes are 3ft. 

 or more long, much-branched, gracefully arched, and many- 

 flowered ; flowers iJjin. across ; sepals and petals narrow, wavy, 

 free, |in. long, white, banded with rosy-purple ; lip three-lobed, 

 narrow in the middle, the lobes concave, pure white ; crest 

 fleshy, five-toothed. The flowers are fragrant, and remain fresh 

 for about a month. Well-grown examples of this species are not 

 uncommon in cohections, and when bearing their numerous 

 spikes of pretty flowers in autumn are very ornamental. The 

 plant requires cool-house treatment, thriving when grown in a pot 

 of peat and sphagnum, and supplied with moisture at all times. 

 (B. M., t, 4S24.) 



\'ar. album has flowers wholly white, save for the yellow 

 disk on the base of the labellum. 



O. Jonesianum (Rchb. f.). — Considerable variety in the size 

 and marking of the flowers characterises this beautiful, distinct, 

 and very effective plant. It has scarcely-perceptible pseudo- 

 bulbs, and thick, fleshy, rush-like leaves, which usually hang 

 downwards, and are from 3in. to i2in. long. The flower- 

 spikes are developed from the base of the last-matured 

 growth, and vary in length from 6in. to 2ft. The strongest 

 spikes bear as many as a dozen flowers, each of which is 2in. 

 across; sepals and petals equal, oblong, wavy, iMn. ni length,
