 with 3-fid. pinnatifid lobes: peduncles slender, 2-fld.; 

 fls. small, bright crimson. June to Oct. Amer., Eu., 

 Asia and N. Afr. B.B. 2:341. For the rockery, in a 

 moist soil and some shade, and will carpet the ground in 

 a few seasons, from seed. Annual; or possibly biennial.

 cuspidate, silvery; petals ovate or nearly round, pale 

 rose, or sometimes white, much longer than the sepals.

 to be grown in temperate house. 



Little known in Amer. but a desir- 

 able greenhouse plant.

 stemmed perennial from a thick- 

 ened rootstock or tube: Ivs. gla-

 hairy; sepals oblong, mucronate, 

 the mucro almost ^in. long; petals 

 2-3 times as long as the sepals,

 grown in the temperate house,
