Silphium laciniatum, L. On the railway right of way near 
Sheldon. Only basal leaves were found, these being elliptical 
or elliptical-lanceolate in outline, acute at both ends, entire to 
pinnatifid with oblong lanceolate, acute, entire lobes, the larger 
leaves often a meter or more in length with a blade about 26 
em wide and a petiole equalling its own length. No. 6824, Sep- 
tember 19. 
Heliopsis helianthoides (L.) Sweet. On the banks of the 
Clinton at Mt. Clemens. Rather scarce. No. 6858, October 10. 
Heliopsis scabra, Dunal, var. intermedia, Farwell. This is 
the commonest Heliopsis in southeastern Michigan. Oxford, 
No. 6673, August 8, 1928. , 
Rudbeckia laciniata, L. Near Denton, No. 6819, September 
19. Nearby we also found as an escape from cultivation the 
double-flowered form called Golden Glow; No. 6820, Septem- 
ber 19. 
Rudbeckia triloba, L. Plentiful along the banks of the Bell 
River at Marine City; No. 6737, August 29. 
Helianthus lenticularis, Dougl. Near Denton, No. 6818, 
September 19. 
Helianthus scaberrimus, Ell., var. subrhomboideus (Rydb.) 
n. comb. H. subrhomboideus Rydb. Mem. N. Y. Bot. Gard. I 
(1900) 419. Reported as H. scaberrimus Ell. page 262, 19th 
Ann. Rpt. of the Mich. Acad. Sci. Except that of size, there 
seems to be no constant character by which this can be sepa- 
rated from H. scaberrimus; it is therefore better treated as a 
variety of it, if accorded a recognizable categorical rank.

Cosmos bipinnatus, Cav. An escape from cultivation. Waste

Tussilago Farfara, L. As reported’in my last paper, this 
species was found in a tamarack swamp near Washington; 
there were two patches of it; one, near the edge underneath 
the tamaracks and another in the heart of the swamp, under- 
neath cedars. On May 23, 1923, a half mile distant from the 
swamp, southerly, toward Washington, another patch was
