raceme simple. 
Description, &c The flowers of this species are very remarkable in their shape and colour. The two 
horns or spurs of the flower are white, tipped with bright yellow at the upper end. Notwithstanding the 
oddness of their shape, the flowers are pretty from the brilliancy of the white spurs, and the contrast it affords 
to the bright yellow of the upper part of the flower. The root is tuberous, and very bitter. This species is a 
native of North America, whence it was introduced in 1731. It grows nearly a foot high, and flowers from 
May to July. It grows freely in any light rich garden soil, and forms a very pretty border flower.

Description, &c. — This very beautiful species was one of the many showy plants discovered by the late 
Mr. Menzies at Nootka Sound ; and it was introduced by him in 1796, being first planted in the royal garden at 
Kew. It is very ornamental, from its beautiful pink flowers. The root is fleshy and creeping, so that a single 
plant soon spreads into a tuft. It is quite hardy, and it will grow well in any common garden soil. 
3.— DIELYTRA EXIMIA, Dec. THE CHOICE DIELYTRA. 
SvNONYME, — Fumaria eximia, Ker. I Specific Character. — Spurs 2, somewhat incurved, blunt, short ; 
Engravings. — Bot. Reg. t. 50. | scape naked ; racemes compound ; stigma four-angled. (G. Don.) 
Description, &c. — This species is nearly allied to the last, but the flowers are larger and more purple. It 
is a native of North America, whence it was introduced by the botanical collector, Lyon, in 1812. In the 
Botanical Register it is called "the most ornamental plant of the genus ; and in a situation that suits it, it soon 
forms a large close tuft, throwing up stems of nearly three feet in height, with bunches of flowers in proportion. 
The foliage is of considerable breadth, and of a peculiarly lively and tender green." It blooms in May and June, 
is perfectly hardy ; and it is propagated by dividing the tuberous knots that compose the root.
