O. POLYXANTHUM GRANDIFLORUM, PFiZZiamg.— A beautiful variety, which 

 flowered in the collection of "W. Lee, Esq., at Leatherhead. Flowers showy, 

 measuring; about 4 inches across, yellow heavily spotted with bright chestnut- 

 brown ; sepals lanceolate acuminate, entire, spreading, somewhat recurved at the 

 tip, deep ochre-yellow, marked with a few large blotches of irregular form, and 

 of a rich deep brown colour, the upper one, which is some distance from the apex, 

 being the largest, and the others extending to the base, petals about the same 

 size and form, of the same rich deep yellow with brown markings, but the 

 blotches on these arc smaller and confined to the basal third of the surface ; lip 

 stalked, the stalk appressed to the column fully half-way up, rouudish-oblong, 

 concave, cordate at the base, toothed at the margin, cuspidate at the apex, almost 

 wholly covered with a blotch of glossy chocolate-brown, with a very narrow 

 border of white, and marked with a scolloped spot of light yellow towards the 

 disk, which bears a prominent crest of two oblong dentate lobes running out to a 

 point in front, and is yellow with a few red-brown striae on the broader portion.

O. PRAENITENS, Rclib.f. — A very interesting species, whose flowers are in 

 the way of those of 0. triumphans, but smaller, though with clear shining 

 colours, which make them very efEective. The sepals and very wavy petals are 

 bright shining sulphur-yellow with a few large maroon-brown blotches ; and the 

 lip has the claw white, and its anterior part yellow, marked in the centre with a 

 cinnamon-coloured blotch. It flowers in the spring months. At one time the 

 late Prof. Reichenbach thought it might be a natural mule between 0. iriwnvplums 

 and O. Iripudians, but the shape of the lip, recalling that of the old Miltonia 

 eun?ata, induced him to alter this opinion. — Xem Grenada. 



O. PRAESTANS, Echh.f.et Warsc. — This, according to Eeichenbach, is much 

 in the way of 0. odoratum, but is distinguished from that species by its sepals 

 and petals being internally maroon-brown from the middle to the top, the calli 

 being peculiarly serrate. — Ocaiia, Xcw Grenada, Peru.

O. PRIONOPETALUM, Lawrence. — A very handsome and distinct species of 

 the 0. luteo-purpureum section, producing large flowers which measure upwards 

 of 4 inches across. The sepals are linear-lanceolate, with entire edges, rich 

 yellow heavily spotted and barred with bright chestnut-brown, the petals are 

 broader, being deeply serrated at the margins, similar in colour to the sepals ; 

 the lip sub-panduriform, dentate at the edge, blade white in front, pale yellow 

 behind, with a large transverse brown blotch in the centre. It flowers in 

 spring. — New Grenada.
