Vaccinium anqustifolium Ait 



la. Vaccinium stamineum var. neglectum (Small) Deam. Map 1583. 

 This variety seems to be merely a glabrous form of the species and my 

 specimens show that its range in Indiana is much the same as that of 

 the species. 



Pa. to middle Ga., westw. to Ind., Ky., and Tenn. 



2. Vaccinium arboreum Marsh. (Batodendron arbor eum (Marsh.) 

 Nutt.) Farkleberry. Map 1584. This is a straggling shrub up to 9 feet 

 high, usually found in shallow soil on sandstone ridges and bluffs where 

 it is associated with post and black oaks. 



Va. to Ind., southw. to Fla. and Tex. 



3. Vaccinium corymbosum L. Highbush Blueberry. Map 1585. This 

 species is restricted to the lake area where it was formerly frequent to 

 common over large areas. It grows in boggy and swampy places in tama- 

 rack bogs, marshes, and interdunal sloughs. Before the lake area was 

 drained it covered hundreds of acres of swamp land but there now remain 

 only a few small blueberry marshes. 



Maine to Minn, and southw. to Fla. and La. 



The following varieties are of questionable value : 



3a. Vaccinium corymbosum var. amoenum (Ait.) Gray. This form has 

 been reported from Lake County by Hill and from Montgomery County by 

 Grimes. I have seen the Grimes specimen, which is now in the herbarium 

 of DePauw University, and it should be referred to Vaccinium corymbosum 

 var. pallidum. 



The range of the variety is given as the same as that of the species. 

 I have it from De Kalb, Lagrange, La Porte, and Porter Counties. 



3b. Vaccinium corymbosum var. pallidum (Ait.) Gray. This form has 

 been reported from Indiana but since its range is given as Virginia to 

 South Carolina, it is doubtful whether it occurs in Indiana. There is, how- 

 ever, a shrub mostly 3-5 feet high in the "knobs" of the unglaciated area
