576 Rosaceae Rosa 



in the lake area. It grows in wet places about lakes, on the borders of 

 swamps in woodland, and along low roadsides. 

 N. S. to Minn., southw. to Fla. and Miss. 



5. Rosa Carolina L. (Rosa humilis Marsh, of Gray, Man., ed. 7 and 

 Rosa virginiana Mill, of Britton and Brown, Illus. Flora, ed. 2.) Pasture 

 Rose. Map 1177. This is our most common rose and should be considered 

 as frequent throughout the state. It is found in hard, clay soil, associated 

 with white and. black oak in open woodland and clearings, in very dry, 

 sandy soils in all parts of the state, and rarely in wet or moist soil of our 

 prairies. 



Newf. to Minn., southw. to Fla. and Tex. 



Of this species Indiana has the following named varieties : 



5a. Rosa Carolina var. villosa (Best) Render. (Rosa Lyoni Pursh.) 

 Map 1178. This is a form with the under surface of the leaflets more or 

 less densely pubescent. 



5b. Rosa Carolina var. glandulosa (Crep.) Farw. (Rosa serrulata Raf.) 

 This form is distinguished by the double-serrate leaflets, by the secondary 

 teeth ending in a stipitate gland, and by the entire part of the margins of 

 the leaflets having stipitate glands. This form is not well marked in our 

 area since specimens can be found with a few leaves with double-serrate 

 leaflets with stipitate glands and the other leaves non-glandular or with 

 simple serrations. I have specimens of this form from Clark, Floyd, and 

 Franklin Counties. 



5c. Rosa Carolina var. sabulosa Erlanson. This form is characterized 

 by the trailing habit of the old stems, "by the uniformly small leaflets on 

 old wood, and by having the hypanthium and pedicels free from hispid 

 glands." It is represented by specimens from Lake County. 



5d. Rosa Carolina var. Deamii (Erlanson) Deam, comb. nov. (Rosa 

 Deamii Erlanson, Rhodora 30 : 120-121. 1928.) This rare form has been 

 found only in Tipton County in the area of the Indian Prairie along the 

 railroad about a half mile west of Goldsmith. It is distinguished "by the 

 recurved stems; long prickles; thick, shining, dark green foliage with 

 coarse serrations; large flowers and hips. All parts are coarse and well 

 developed." I have had this form under cultivation ever since I found it. 



5e. Rosa Carolina var. obovata (Raf.) Deam, comb. nov. (Rosa obovata 

 Raf., Ann. Gen. Sci. Phys. 5: 217. 1820.) This form is rather frequent 

 in Indiana, especially in the northern part. It is distinguished by its 

 broad, oval leaflets, stout prickles, and large flowers. 



6. Rosa blanda Ait. Meadow Rose. Map 1179. This species is, for the 

 most part, restricted to the area about Lake Michigan where it is found 

 in the low, interdunal flats and up to the very tops of the highest dunes. 

 On account of many visitors to the high dunes it has already almost dis- 

 appeared from this habitat. 1 have it also from Elkhart County and Grimes 

 found it along the railroad in Putnam County where it was a migrant.
