ODONTOGLOSSUM. 597 



supposed natural hybrid 0. Wilckeanum, Reichenbach fil, who at the time he 

 named it guessed that it was a natural mule between these two species. The 

 pseudobulbs are similar to those of 0. crispum, but somewhat rounder flowers, 

 Sj inches across, sepals and petals nearly equal ; sepals pale yellow, each having 

 three reddish-brown bars; petals lighter in colour having a large blotch in 

 the centre and two smaller rounded ones at the side ; lip somewhat like 0. luteo- 

 pitrpureum in shape, and having a large reddish-brown blotch. — Oarden hybrid.

O. 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 communicated to us by Mr. Grossart, when 

 gardener to J. Buchanan, Esq., of Edinburgh, in 1885.— U. S. of Colombia.

O. WILCKEANUM SULPHUREUM, Echb.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. — U. S. of 

 Colombia. 



O. WILLIAMSIANUM, Bchb. /.—A very beautiful large-flowered plant of 

 noble proportions, supposed to be a natural hybrid between 0. grande and 

 0. Schlieperianum. It has ovate compressed tufted pseudobulbs, ligulate oblong 

 acute leaves, and erect scapes bearing a dense oblong raceme of about a dozen 

 flowers. These flowers are about 4^ inches across and about the same in depth, 

 the lanceolate wavy sepals greenish-yellow heavily barred with chestnut-brown ; 

 and the broad oblong blunt-ended wavy petals pale yellow with a large pale 

 reddish-brown, darker-veined patch at the base, which is distinctly clawed. The 

 lip, which resembles that of 0. Schlieperianum in shape, as also do the crests and 

 the column, is creamy white in the anterior portion, with a few pale flesh- 

 coloured blotches at the base. This plant was imported along with 0. Schlie- 

 perianum, which it resembles in growth, and is now in the collection of M. le 

 Oomte A. de Germiny, Gouville, France, and produced in June, 1893, twenty 

 flowers on one spike. It flowers in June and July. — Costa Rica.
