0. 'Warsceviczii, Bchb. f. — A rare and interesting orna- 

 mental species, remarkable for the great spathaeeous bracts 

 of its flower scape. The pseudobulbs are ovate, compressed, 

 two-leaved, the leaves narrow oblanceolate, and the flowers 

 in racemes a foot long, from twelve to seventeen being borne 

 on the raceme. The sepals and petals are oblong-lanceolate 

 obtuse, the petals broader and blunter, while the lip is 

 broadly cuneate and auricled at the base, with a long narrow 

 isthmus, which is thickened and blunt-angled on each side, and 

 is continued into a broad reniform bilobed apex. The flowers 

 are golden yellow, the borders of the isthmus tinted with 

 brown. There is a crest of three raised lines on the disk. The 

 0. hifrons of Dr. Lindley is regarded as a starved specimen 

 of this plant by Reichenbach, who states that it perishes as 

 soon as it descends into the warm zone. — Costa Fdca, at an 

 elevation of 8,000 to 10,000 feet, growing on oaks.

0. xanthodon, Echb. /. — A very striking plant of the 0. 

 serratwn section, and one which, although the flowers are 

 not so large as in that species, yet makes a good display 

 from their being very freely produced. In habit of growth it 

 closely resembles 0. serratum. The pseudobulbs are five 

 inches long, narrow ovoid, much compressed ; the leaves 

 narrow linear-obovate, two feet long, one at the apex and several 

 equitantly sheathing the base of the bulb. The scape is six 

 to eight feet long, twining, bearing a large flexuosely branched 

 panicle of numerous flowers, which have the clawed obovate- 

 rotundate undulate -crisped crenate sepals and petals of a 

 rich dark brown, bordered with bright yellow, the smaller 

 narrower obovate recurved lip being of the same colours with 

 the basal portion yellow, irregularly quadrate, and bearing a 

 crest of several tubercular caUi. — Ecuador.
