 (its faint oilor like that of apples), pure white, 4'-9' in diameter; petals 

 proportionately broader and blunter ; leaves 8'-15' wide ; seeds almost 

 globular; rootstock bearing copious tubers like "artichokes," attached 

 by a narrow neck and spontaneously separating. W. N. Y. and Penn.,

* * Flowers colored ; eoMtic or southern. 



N. siellata, Willd. (or N. ccerxjlea), Blue W., cult, in aquaria ; a ten-

 large red or whitish flowers, with red-margined sepals, and peltate, sharply 

 serrate leaves which are pubescent below. N. RtruRA and N. Devonien- 

 sis are forms of it ; and from the latter garden form the variety known 

 as N. SturtevAntii originated. 



N. fliva, Leitn. Yellow W. Leaves broadly oval with wavy margins, 

 the lobes at base of notch not pointed ; flowers bright, light yellow ; petals 

 sub-acute. Florida.
