From Flora of Indiana (1940) by Charles C. Deam
This is a local species found only in marly springy places. Where it is found, it is usually a common plant. Its absence in the northeastern part of the state is of interest. If it occurs there, it is rare, because I have collected intensively in these counties without finding it.
Stout, glabrous perennial 6-18 dm from a short, tuberous-thickened base and fleshy-fibrous roots; stem striate-angled; lvs thick and firm, entire or nearly so, with several prominent longitudinal nerves converging toward the summit; basal and lowermost cauline lvs conspicuously long-petioled, the blade 6-20 × 2-10 cm, commonly elliptic and tapering to the base, or deltoid-ovate and subtruncate in robust specimens; cauline lvs few, conspicuously reduced upwards, becoming sessile or subsessile; otherwise as in no. 2 [Cacalia muehlenbergii (Sch. Bip.) Fernald]; 2n=54. Wet prairies and marshy or boggy places; O. and s. Ont. to Minn. and e. S.D., s. to Ala. and Tex. June-Aug. (C. tuberosa; Mesadenia t.)
