4. Aster Shortii Lindl. {Aster Shortii Hook.) Short's Aster. Map 

 2036. Infrequent to frequent in dry woods throughout the state, although 

 there are no specimens or records from the northern tier of counties. It 

 is more common toward the bases of wooded slopes. Very variable in the 

 width of the leaves and the pubescence of the under surface of the blades, 

 which varies from a dense, short, harsh pubescence to only a few hairs on 

 the midrib. The bracts are usually more or less densely pubescent, at 

 least ciliate, and generally the rhomboidal, green tip is also pubescent, 

 usually short-acute, rarely acuminate or some of the lower ones subulate. 

 My no. 19155 from Franklin County, collected about 2 miles west of 

 Metamora, is cited as exceptional. This plant is glabrous to the in- 

 florescence; above that it is only slightly pubescent and then only in 

 lines. The leaves are narrow-lanceolate and long-acuminate, entirely 

 glabrous both above and beneath, the margins ciliate and most of them 

 more or less shallow-serrate to about the middle; bracts very narrow, 

 the widest 0.5-0.6 mm wide, long-acuminate, some of the lower subulate- 

 pointed, glabrous or minutely and finely ciliate toward the apex. It seems 

 to agree with the description of Aster cam'ptosorus Small.

5. Aster cordifolius L. Blue Wood Aster. Map 2037. Infrequent to 

 frequent throughout the state in dry woods. This is also a highly variable 

 species and several varieties have been described. None of them have been 

 reported, and I hesitate to report the variation in my specimens under 

 varietal names.

6. Aster sagittifolius Wedemeyer ex Willd. Arrow Aster. Map 2038. 

 Infrequent to frequent in some places throughout the state except the 

 northwestern part, where the variety takes its place. It is found mostly in 

 dry, white oak and black and white oak woods.
