Two forms occur here. In both, the earliest radical leaves are 

 chiefly 3-parted, or 3-lobed. In the first (apparently typical) form 

 the later radical leaves are ternate, each division twice pinnate 

 with oblong or linear lobes ; the cauline similar, the uppermost be- 

 coming simple. Roots fleshy and decidedly thickened. In the 

 second form, the later radical leaves are ternate, the divisions 

 coarsely serrate and wedge-shaped ; the lateral divisions nearly 

 sessile, usually lobed, the terminal stalked, broad and usually 

 2-parted ; the cauline leaves 3-parted, 3-lobed, or the uppermost 

 simple. Roots slender.

 p. 550 (H. andC.) 



The "low, hairy form," creeping and rooting at the nodes freely.
