0. Wilckeanum, Rchb. f. — This is a very distinct and 

 beautiful species, whose long plumose racemes of yellow and 

 brown flowers are very handsome and attractive, as might be 

 expected when Professor Eeichenbach says, " it is just inter- 

 mediate between 0. criqjinn and 0. hctco-purpureum." It 

 was first flowered by M. D. Massange, Marche, Belgium, and 

 is named after his gardener, Herr Wilcke. The pseudobulbs 

 are rather large ovate-oblong, furnished with ligulate oblong 

 leaves in pairs from the apex, and having radical scapes which 

 spring from the axils of accessory leaves, and bear a stout 

 raceme of over a dozen flowers, which are fully three inches 

 across. The lanceolate acuminate wavy sepals are pale yellow 

 with sundry bold blotches of light brown ; the broader petals 

 much serrated at the edges, are of the same yellow colour, but 

 with fewer and smaller brown blotches ; and the denticulate 

 oblong undulated apiculate lip is of a still paler yellow, and 

 has in the front part a roundish oblong blotch of pale brown, 

 the disk being of a deep yellow, with crests consisting of two 

 many-toothed ragged keels. It flowers during the spring 

 months. — New Grenada.

0. Wilckeanum pallens, Bchh. f. — A very handsome 

 variety, of which the sepals and petals are white faintly 

 tinged with yellow and heavily blotched with dull brown, the 

 petals most irregularly serrated ; the lip is white, having a 

 blotch of brown in the centre, and a number of small spots 

 around the crests. A grand spike of this variety was com- 

 municated to us by Mr. Grossart, gardener to J. Buchanan, 

 Esq., of Edinburgh, in 1885. — Colombia.

0. Wilckeamim SUlphureum, Bchb. f. — A fine new variety, 

 with flowers of a bright sulphur yellow, and having a few red 

 blotches and lines on the lip and column, and also one or two 

 red blotches on the lateral sepals. The sepals and petals are 

 much elongated, and the whole flower is very striking. — 

 Colombia. 



0. Willi amsianum, Bchb. f. — A very beautiful large-flowered 

 plant of noble proportions, supposed to be a natural hybrid 

 between 0. grande and 0. Schlieperianum. It has oval com-
