clothed with tufts of stellated patent hairs. Leaves on petioles 
nearly as long as themselves, cordate with a deep sinus at the 
base, three-, but more generally deeply tive-lobed, the lobes 
obovate, obtuse or retuse and again lobed and serrated or 
toothed at the margin. Stipules subulate, deciduous. Peduncles 
longer than the leaves, terete, single-flowered, axillary, solitary, 
with a joint above the middle, and there bearing two or three 
small, subulate bracteas. Involucre cup-shaped, hemispherical, 
longitudinally ribbed, and cut into ten to twelve subulate 
teeth or segments. Calyx deeply 5-fid, twice as long as the 
involucre; the segments ovate, acuminate, ribbed. Corolla large 
handsome, rich blueish-purple, slightly downy in a broad line 
outside on each petal. Petals triangular, obovate, oblique; 
one angle rounded, the opposite one sharp and mucronate. 
Column of stamens elongated, free portions of the filaments 
spreading. Style longer than the tube, stigma dilated, with 
five obtuse rays. Young fruit elliptical, shorter than the calyx, 
stellato-pubescent.
