thread. Stem none. Leaflets of a delicate bright green, often 

 purplish at the back, drooping at night, on long, hairy, radical, 

 purplish/oo<s/a/A;s. Flower-stalks taller than the footstalks, like 

 them hairy, purplish, more or less curved or wavy. Bracteas 2, 

 opposite, considerably below the top of each stalk, Fl. solitary, 

 drooping, bell-shaped, either white or purplish, always streaked 

 with fine branching purple veins ; the petals adhering together

 the south of Italy, the Wood-sorrel is said to be called Juliola,

 leaflets inversely heart-shaped, downy, acid like the former. Sti-

 by the want of which in O. stricta Mr. Salisbury has well distin-

 reported to be of American origin. The Jloivers of O. corniculata,
