O. VUYLSTEKEANUM, Echh. /.—Professor Eeichenbach in describing this 

 species says: — "A grand thing. Take an Odontoglossum mulua sulphureum, 

 give it a lip much dilated at the top, and add the sharp edges of the petals of 

 Odontoglossimi Wilcl-eanum." The whole flower is sulphur-coloured, with the 

 few blotches of the odd sepal, the petals, and the lip of the " deepest richest 

 dazzling orange " ; the lateral sepals are also of that colour, except at their base. 

 — New Grenada.

O. WALLISII, Bclib. f. — A slender and graceful plant, with something the 

 aspect of 0. Lindhyanum, but superior to that species on account of the more 

 pleasing colour of the lip. The pseudobulbs are ovoid ancipitous, the leaves 

 linear-lanceolate plicate, and the flowers 2^ inches across, pedicellate, racemose, 

 on a slender scape ; the sepals and petals are oblong-lanceolate, the former more 

 narrowed to the base, with a long central bar of reddish brown and a narrow 

 even edge of pale yellow, the latter with the central colour more broken up and 

 the yellow edge broader ; the lip has the base tubuloso-clavate, and the 

 limb ovate, constricted in the middle, fimbriate, with a deourved front, white, 

 having a double crest with six 

 spreading horns at the base of 

 the lamina, and behind these a 

 series of rosy-purple streaks, 

 the anterior half being of the 

 same rosy tint edged with 

 white, and marked by a half- 

 circular white loop. It blooms 

 during the winter months. — 

 Xew Grenada.

O. WARNERIANUM, Rchh.f. 

 ■ — This very rare and handsome 

 species forms as it were " a 

 connecting link between O. 

 iiebulosum and 0. Roasii, having 

 the broad petals of the former, 

 and the slender narrow pseudo- 

 bulbs of the latter." The plant 

 is dwarf in habit, and the 

 scape, which is longer than the 

 leaves, bears four or five flowers. The pseudobulbs are tufted narrow elongate 

 ovate monophyllous, the leaves ligulate acute, and the flowers about 3 inches 

 across ; the sepals are oblong acute, white with a few transverse brownish-red 

 bars, the dorsal one having also an ocellate spot at the base; the petals are 

 blunter and wavyi, white with an ocellate basal mark enclosed by a semi-circle 

 of roundish brownish-red spots ; and the lip broad cordate-triangular obtuse
