0. Yaricosum Eogersii, Rchb.f. — An exceedingly showy and 

 beautiful free-flowering plant, which is now generally considered 

 to be a Tariety of 0. varicosum, to which it is evidently closely 

 related. It has oblong ovate furrowed pseudobulbs, which 

 bear two ligulate lanceolate leaves, and from their side a large 

 densely branched nodding panicle which sometimes bears as 

 many as one hundred and seventy flowers, each measuring 

 about two and a half inches across. The sepals and petals 

 are comparatively small, the lip large, reniform, flat and 

 spreading, deeply four-lobed in front, and rich golden yellow 

 in colour, with a few bars of red brown at the base. It blooms 

 during winter, and should be grown in the Cattleya house, 

 potted in peat and sphagnum moss. — Brazil.

Oi variegatum, Swartz. — A pretty dwarf-growing species 

 with fleshy equitant acuminate serrulate leaves three or four 

 inches long, and of a dark green colour, the branching upright 

 panicles six inches to a foot and a half high, bearing many 

 blossoms of a rosy pink colour, richly stained with cinnamon 

 red on the petals and at the base of the sepals and lip, these 

 blossoms continuing in beauty for several weeks. The petals 

 are largish obovate clawed, the apex emarginate and cuspi- 

 date ; and the lip bears two small acute lateral lobes, and 

 has a broad two-parted middle lobe with a denticulate claw, 

 and a crest consisting of two sets of tubercles. It is best 

 grown on a block with plenty of moisture at the roots. —

0. Warneri, Lindley. — A very pleasing and distinct dwarf- 

 growing species, with csespitose ovate ancipitous subangulate 

 pseudobulbs, which are two-leaved, the leaves linear-lanceo- 

 late and recurved. The flowers grow in short racemes of 

 five to eight together, the sepals being oval, spreading, the petals 

 somewhat narrower and ascendent, and the lip three-lobed 

 flat, with the middle lobe cuneate and deeply parted into two 

 roundish lobes. There are two varieties, in both of which the 

 lip is of a bright yellow ; but in one {sordidum) the sepals 

 and petals are dull yellow streaked with purple, and in the 

 other (piu-puratum) the sepals and petals are white streaked 

 with bright purple. This latter form is the most desirable
