Engkavings. — Lodd. Bot. Cab. t. 1858 ; and Bot. Mag. t. 3448. I with spreading hairs, particularly at the joints, which arc swollen. 
Specific Character. — Petioles filiform, dichotomon sparingly covered I Petals flat. 
Description, &c. — This species diflfers widely from all the others in the shape and colours of its flowers, 
which are white and quite flat. The leaves, however, and all the parts of fructification are exactly the same as 
in the other species. This species is said to have been introduced from North America, in 1812. Its flowers are 
rather pretty, but scarcely enough so to make the plant worth cultivating. 
terior petals orate-lanceolate ; interior ones twice as long, and ending 
in a spur.

Description, &c. — This is by far the prettiest of the genus. It is a native of Japan, whence it was 
introduced in 1840. It is quite hardy, and very well adapted for rock work, or any other situation usually 
planted with Alpines j but, like all similar plants, it is easily killed by extremes of drought or moisture. " It 
flowers in April and May, and it may be increased by division of the roots when in a dormant state ; but, 
like the other species of the genus, it has never yet been found to seed." (See Bot. Reg. for 1840.)
