9. Viola hirsutula Brainerd. Map 1441. My only specimen was col- 

 lected on a black oak and Virginia pine slope about 2 miles northwest of 

 Bennettsville in Clark County. On this same slope I collected the following 

 hybrids, all of which were named by Dr. Brainerd. 



9a. X Viola cordifdlia (Nutt.) Schwein. (Viola hirsutula X papiliorwcea 

 Brainerd.) 



9b. X Viola dissita House. (Viola hirsutula X triloba Brainerd.) 

 9c. Viola hirsutula X missouriensis (never described). 



10. Viola sagittata Ait. Arrowleaf Violet. Map 1442. In northern 

 Indiana this species is generally found in black, moist, sandy soil in the 

 open or in open woods. Rather local. Probably absent in many of the 

 central counties, appearing again in southeastern Indiana in slightly acid 

 soil in the sweet gum flats; in the knobstone area on or near the crests 

 of Virginia pine and chestnut oak ridges ; and in southwestern Indiana in 

 the post oak flats. Rare in southern Indiana.

10a. Viola sagittata var. ovata (Nutt.) T. & G. (Viola fimbriatula Smith 

 of Gray, Man., ed. 7 and Britton and Brown, Illus. Flora, ed. 2.) This 

 variety is a form with more ovate and shorter leaf blades and is more or 

 less densely pubescent. It insensibly grades into the typical form. 



In Indiana mostly near Lake Michigan and in Posey County. 



10b. Viola sagittata X sororia Brainerd. Lake County. 



11. Viola lanceolata L. Lanceleaf Violet. Map 1443. Rather local 

 but usually frequent to abundant where it is found in the lake area. 

 Usually in a sandy black loam soil in the open in marshes, on the borders 

 of swamps, and in bogs. Probably absent in most of the counties imme- 

 diately south of the lake area but common on the slightly acid soil of the 

 flats of southern Indiana. Here it is locally abundant in old fallow, wet
