Aster praealtus Poir 



It is also found in prairie habitats and in Posey County I found it on the 

 bank of a pond that usually overflows each year. The great variation of 

 this species in the shape and width of the leaves (1-4 cm wide), and in 

 the form of the inflorescence has resulted in the description of 9 varieties. 

 The involucres of my specimens are usually 6-7 mm long. The upper bracts 

 are mostly 1-1.4 mm wide, abruptly acute (rarely acuminate) and usually 

 with slightly spreading tips. An exception is my no. 11970, collected 

 August 4, 1912, along the railroad about a mile east of Dana in Ver- 

 million County. In this the inflorescence is fastigiate and very leafy; the 

 involucres are 8-10 mm long and the bracts are narrower than those of 

 the typical form and are long-acuminate.

13a. Aster laevis var. falcatus Farw. (Rept. Michigan Acad. Sci. 21 : 

 370. 1920.) Farwell describes this variety as follows: "Panicle usually 

 shorter and ovate; median stem leaves usually broadest at the auriculate 

 base, linear or oblong-lanceolate, under three fourths inch wide and often 

 6 inches long, some of them falcate; small subulate leaves as in the pre- 

 ceding variety" (var. laevigatas) . I have this variety from the wooded 

 sand hills about 3 miles south of Ft. Wayne, Allen County, and from an 

 upland woods about 2 miles south of Oriole, Perry County. The specimens 

 are deposited in the Gray Herbarium. 



14. Aster longifdlius Lam. Longleaf Aster. Map 2048. This species 

 has been reported from Cass, Noble, and Porter Counties. The specimen 

 collected Sept. 13, 1926, by Dr. Lyon in a subdunal marsh at Tamarack, 

 in Porter County, and one which I collected on the low border of Cogg 

 Lake, about 4 miles south of Lagrange, Lagrange County, are the only 

 specimens which I have seen.
