140 LEAFLETS. 



very conspicuously punctate on both faces, the axils of all 

 bearing short branches not equalling the leaves and densely 

 beset with small linear revolute leaves : flower-clusters small, 

 capitate, their Inner bracts margined by a whitish-woolly 

 tomentum, as are also scarcely more than deltoid short calyx- 

 teeth : corolla pinkish, purple-dotted. 



Species apparently local on prairies near Chicago ; collected

1901. 



KoELLiA HuRONENSis. Plant nearly a yard high, not 

 stout for the height, the internodes long, axillary sterile 

 branches elongated slender, only sparsely leafy, the whole 

 plant deep- green, to the unaided eye glabrous, a lens showing 

 the angles of the stem pubescent with hirtellous short hairs : 

 main leaves elliptic-lanceolate, subsessile, 2 to 2^ inches long, 

 not revolute, remotely denticulate, thin, glabrous on both 

 faces or with a scanty short pubescence on the midvein and 

 margins, veiny with about 5 pairs of feather veins, rather 

 closely small-punctate : verticillasters in short spikes of 2, 3 

 or 4 terminating the few uppermost branches, nearly V^ inch 

 in diameter, barely ^ inch high : calyx hoary with a minute 

 pubescence, the teeth more so, triangular but longer than 

 broad, equal: corolla not seen. 



Open prairie-like ground at Cassville, Michigan, on Saginaw 

 Bay, an arm of Lake Huron; type specimens collected by 

 Mr. Charles K. Dodge, 9 Sept., 1910. Its deep-green and 

 glabrous aspect distinguishes it from all other K. mutica allies. 



KoELLiA cuRviPES. Stems stoutish and rigid, rather 

 acutely angled, 2 feet high, all parts equably tomentellous- 

 puberulent, not even the angles showing other indument, all 

 the foliage pale yellow-green as to the upper face, which is 

 tomentellous like the stem, but lower face white with a denser 

 tomentum, without traces of hairiness even on the veins ; 

 main leaves ovate, lYz inches long, lightly serrate-denticulate,
