0. anthrocreiie, Echb.f. — A very distinct and curious species, 

 somewhat resembling Miltonia Warscewiczii in its manner of 

 growth. It produces large upright branched spikes of dark- 

 coloured flowers, having the sepals and petals much undulated, 

 chocolate brown transversely barred with yellow towards the 

 base, and the lip white ; it flowers during the winter months. — 

 Peru. 



0, aurosum. — See Oncidium excavatum. 



0. barbatum ciliatum, Lindley. — A pretty dwarf compact- 

 habited plant, with ovate compressed pseudobulbs, bearing a 

 solitary linear-oblong leaf two or three inches long, and pro- 

 ducing a slender erect flexuose scape spotted with red, and 

 terminated by a few yellow flowers spotted with crimson, the 

 lip being wholly yellow, equally three-lobed, and bearing a 

 five-horned crest at its base. It succeeds best on a block, but 

 it must have good attention as to the supply of water at the 

 roots. — Brazil.

0. Batemaniliaillllll, Knowles and Westcott. — A beautiful 

 and distinct though somewhat variable species, growing 

 about eighteen inches high, and having oblong compressed 

 diphyllous pseudobulbs, and erect oblong pale green leaves. 

 The flowers grow in erect racemes, or in large branched 

 panicles (ramosum), and have ovate acute sepals, broader 

 petals, and a large roundish emarginate three-lobed lip which 

 is clear yellow, the small sepals and petals being of a brownish 

 pm-ple, and the base of the lip of the same colour. There 

 are two varieties, one (a) with racemes, the other (b) with a 

 panicled inflorescence. It is rather a shy-flowering plant, but 

 one which is worth growing on account of its beautiful bright 

 yellow flowers, which are produced at difi"erent times of the 

 year. It belongs to the section Verrucituherculata, and has 

 a prominent crest consisting of three to five short plates at 

 the base, and three others in front, diverging irregularly lobed,
