the lip has roundish lateral lobes and an intermediate roundish sub-cordato 

 emarginate lobe of a pale yellow spotted with red ; the crest forms a pubescent 

 four-lobed cushion; this, when well gi-own, is a useful plant for all purposes ; pot 

 culture suits it best. — Brazil.

O. ELEGANTISSIMUM, Ec7t6. /.—Although this species was described in 1877, 

 it still appears to be somewhat rare in collections. It is an elegant plant producing 

 short broad-ribbed glaucous pseudobulbs, which carry two leaves each ; flower 

 scapes in the way of 0. curtwm; sepals brown with narrow yellow bands ; petals 

 yellow spotted with brown ; lip bright yellow, front lobe marbled and dotted 

 with light brown; the calli being bordered with black-purple. Flowers in 

 summer. — Native country not stated. 



O. EURYCLINE, Bclib. f. — This pretty dwarf-growing species is very distinct. 

 It has ligulate obtuse costate pseudobulbs, solitary cuneate-ligulate leaves, and 

 two-flowered peduncles; the flowers have the sepals and petals light reddish 

 ochre with a few dark bars at their base, the lateral sepals being a little longer 

 than the lip, which is yellow with numerous brown spots at the base, having 

 rounded retrorse basilar lobes or auricles, and a cordate reniform bilobulate 

 anterior lobe. It flowers in December. It was first bloomed by W. E. Brymer, 

 Esq., Ilsingtou House, Dorchester. — Venezuela. 



O. EUXANTHINUM, Bchb. f. — A very pretty species belonging to the group 

 represented by 0. bifolium, and requiring sim.ilar treatment. The pseudobulbs 

 are 2 to 3 inches long, ellipsoid compressed and furrowed, bearing a pair of linear 

 ensiform acute keeled leaves ; the numerous flowers grow in ample panicles, and 

 are about 1 inch across, and very showy ; the sepals and petals are small, yellow, 

 dotted over with red, the lip large shortly clawed, with the claw protruded and 

 winged, three-lobed, the lateral lobes large roundish crenate, the middle lobo 

 much longer reniform bilobed, with numerous red spots on the disk between the 

 lateral lobes, the rest of the surface rich clear yellow ; the two column wings 

 are spreading, yellow with red spots ; the broad lip, large rounded side lobes, 

 and conspicuous spotting make the flowers not only pleasing but showy. It 

 blooms during the autumn months. — Brazil.

O. EXCAVATUM, Lindl. — ^A robust-growing species with light green pseudo- 

 bulbs, oblong-ligulate leaves, and long branched scapes bearing an abundance of 

 brightly-coloured flowers, the sepals and petals being rich yellow profusely 

 blotched with cinnamon brown near the base, and the pandurate lip also deep 

 golden yellow blotched only on the crest, which is very convex and excavated in 

 front, the base being cordate, and the tip rounded and emarginate. According 

 to Lindley, 0. aurosum can scarcely be distinguished from this plant, though 

 its flowers are perhaps a little larger, its panicle more compact, and its crest 

 very rugose. It should be potted in good fibrous peat, and placed in the cool 

 house; flowers in late autumn. — Peru.
