Rhodora 40:356. 1938 as "Muhlenbergii"
Comment:
an illegitimate, superfluous name (Melbourne ICN Art. 52) originally based on Senecio muehlenbergii Sch. Bip., an illegitimate, superfluous name for C. reniformis Muhl. ex Willd. and the replaced synonym of Mesadenus reniformis (Hook.) Raf., so there is no parenthetical authorship (Melbourne ICN Art. 58)
