Habit	Sub-glabrous to densely hairy perennial from slender, horizontal rhizomes, the flowering stems 5-20 cm. tall.	Stiff-hairy perennial from a branched, woody base, the stems 1-2 dm. tall.
Leaves	Basal leaves several, the blades cordate-reniform, 1.5-3 cm. broad, ternate, the leaflets wedge-shaped, coarsely toothed, the lateral pair deeply lobed as well; the flowering stem naked except for a whorl of 3 leaves above the midpoint, these simple but deeply tri-lobed.
