NATURAL ORDER. 
ORCHIDEJE. 
Generic Character. — See vol. iii. p. .97. 
Specific Character. — Epiphyte. Leaves lanceolate, acuminate, smooth, about a foot in length. 
Scape arising from the base of the bulbs, smooth two-thirds the length of the leaves. Flowers 
racemose, of a beautiful blue, spotted irregularly with dark-brown spots, very handsome. Petals 
and Sepals ovate, oblong, acute. Labellum (lip) obovate, very broad ; on the disk surrounding 
the column is a fleshy production resembling the lower jaw beset with teeth, which has suggested 
the name Maxillar, tooth-like appearance ; relating to the jaw-bone.

flowers are large, and the lip pure white, except a few radiating lines delicately 
introduced near the base, which look very pretty. 
The species now represented has not such large flowers as those adverted to 
above, nevertheless it is unquestionably the most beautiful and interesting; the 
deep rich blue colour of the lip, and the bright green chocolate of the sepals,
