 in the northern part of the state.

15a. Aster lucidulus (Gray) Wieg. f. firmus (Nees) comb. nov. (Aster 

 firmus Nees, Gen. et Sp. Asterearum : 66. 1832.) This form of the preceding 

 species has sharply serrate leaves. I have specimens from Allen, Marshall, 

 and Steuben Counties which I refer to this form. 



16. Aster praealtus Poir. (Rhodora 35: 21-24. 1933.) (Aster salici- 

 folius Ait. of recent authors.) Map 2050. This species is essentially an in- 

 habitant of moist, prairie habitats. Infrequent in moist prairie habitats 

 and less often in moist, black loam about lakes and in marshes and in low, 

 open woods. 



Ohio to Wis. ( ?) and Kans., southw. to Ky., Tex., and n. Mex. 



16a. Aster praealtus var. angustior Wieg. (Rhodora 35: 24. 1933.) 

 Map 2051. This variety is distinguished from the species by having nar- 

 rower leaves and is found in similar habitats. It is apparently local in its 

 distribution. 



Mass., Ind., and 111. 



16b. Aster praealtus var. subasper (Lindl.) Wieg. This variety was re- 

 ported by Wiegand (Rhodora 35: 25. 1933) from Indiana, as collected by 

 Dr. Clapp, who did his collecting in the vicinity of New Albany. 



Ind. and 111., southw. to Tex. 



17. Aster junceus Ait. Rush Aster. Map 2052. Infrequent to fre- 

 quent in marshes in northern Indiana. With one exception, all of my 

 specimens have white flowers. This species is variable in the size of the 

 heads and branching of the stem. 



N. S. to B. C., southw. to N. J., Ohio, and Colo. 



18. Aster paniculatus Lam. (Rhodora 35: 28-32. 1933.) Panicled
