BOTANICAL GLEANINGS IN MICHIGAN. 20 
Vernonia interior. Small. After many years this again has 
been collected. Monroe, No. 6700, August 22. 
‘Solidago graminifolia (L.) Salisb. In low grounds near 
Orion. These plants are minutely scabrous but are to be re- 
ferred here rather than to the hirtellus var. Nuttallii which is 
everywhere common. This is the first time I have seen the 
typical species in southeastern Michigan. No. 6832, September 
26. 
Aster leavis, L., var. faleatus, Farwell. Ypsilanti, No. 6809, 
Sept. 19. Here also was found a very handsome form with 
violet-purple rays which as a color variation may be put on 
record as Aster laevis, var.,falcatus, forma purpurascens, n. f. 
No. 6811, September 19. 
Aster ericoides, L., var. villosus, T. and G. Waste grounds 
along the shores of St. Clair River at Marine City, No. 6740, 
August 29. : 
Aster ericoides, L., var. platyphyllus, T. and G. Open fields. 
near the Bell River at Marine City, No. 6739, August 29. 
Erigeron Canadense, L., var. pusillum (Nutt.) Barton. A 
low, slender form with a fastigiate tendency. Denton, No. 
6817, Sept. 19. Geddes, No. 6793, Sept. 12, 1923; Oxford No. 
6829, September 19; Avon, No. 6848, October 3. 
Erigeron Canadense, L., var. strictum (DC.) n. comb. Eri- 
geron strictum DC. Prodr. V (1836) 289. Stem simple, strict; 
leaves densely crowded, those at the middle of the stem being 
the longest; inflorescence dense, spiciform 3 to 9 cm long by 1 
to 3 cm wide. The spike or thyrse is as dense as that of Soli- 
dago bicolor to which it bears a superficial resemblance; this is 
a variation that is well worth recognition. Although De Can- 
dolle based his species on Berlandier’s plants from around Be- 
jar, Mexico, there can be no doubt that our plants belong here 
as they agree in every particular with De Candolle’s descrip- 
tion. Growing with the species on waste grounds at Marine 
City, No. 6722, August 29; Oxford No. 6828, September 26; 
Avon, No. 6847, October 3. The Marine City plants are typ- 
ical in every way; but the Oxford and Avon plants are less so 
as the panicles though spiciform are less dense and the leaves 
are not congested.
