leaves with shorter petioles ; blades palmately cleft or parted into linear or linear-cuneate 
segments : flowers in terminal racemes or corymbs: calyx pubescent; lobes triangular or 
triangular-lanceolate, acuminate, less than 1 cm. long: petals pink or rose, 1-1.5 cm. long, 
erose-fimbriate at the top: carpels 4 mm. long, coarsely wrinkled on the back and sides, 
strigillose on top.

7. Callirrhoe digitata Nutt. Perennial by a thick root, more or less villous-hirsute 
below, glabrous above. Stems erect or decum nt, solitary or several together, 3-8 cm.

lades palmately lobed or parted or the earliér ones coarsely crenate : stem-leaves few, with 
shorter petioles ; blades palmately divided, the linear or narrow divisions usually entire, 
em. long: peduncles slender or filiform: involucels wanting: calyx nearly glabrous ; 
lobes ovate to lanceolate, 7-10 mm. long: petals red-purple, white or violet, 1.5-2 cm.
