two-leaved. Leaves ligulate-oblong, acute, channelled toward the base, of a pleasing 
light green colour. Scape radical, supporting a many-flowered raceme, or in the 
more vigorous plants a panicle equalling or exceeding the leaves, and having small 
acute bracts at the base of the pedicels. Flowers exquisitely chaste and beautiful,

-ovate-lanceolate, acuminate, entire or toothed, white, suffused more or less with a

than the petals, oblong-ovate, the margin much crisped and the shortly acuminate

The Princess of Wales’ Odontoglossum, one of the most beautiful and one of 
the most useful of Orchids, was found in the province of Bogota, in New Grenada, 
-at_an altitude of from 7,000 to 8,000 feet, growing in great profusion on the 
branches of trees in the forests of that elevated region. It was introduced to this 
country in 1864 by Mr. Weir, when collecting for the Royal Horticultural Society, 
and was described in that year by Mr. Bateman as above quoted. There cannot 
be two opinions respecting its beauty, as it is one of the finest Orchids in 
cultivation; and though there are amongst the imported plants great diversities in 
-the form and colour of the flowers, yet all are beautiful. Some have the flowers 
of a pure white, in others they are variously suffused with a delicate rosy hue; 
Some are spotted with crimson, and there are those with yellow flowers, but the
