inserted on p. 162 of that paper. The remaining additional 

 species are herbs, and should be classed with the Mcsophytic 

 species of zvood and meadozv.** 



They are as follows : 

 Viola canadensis L. Canada Violet. 



One specimen in flower was collected on a wooded slope. 

 The lower surface of the leaves, the petioles, stipules and 

 peduncles in this specimen are more pubescent than in 

 typical forms of the species. 

 Impatiens fulva Nutt. Spotted Touch-me-not. 



Not rare in marshy, shaded places. 

 Sicvos angulatus L. Star Cucumber. 



Not rare on wooded alluvial bottoms along the Big 

 Sioux river in the large grove. 

 Eupatorium ageratoides L. White Snake-root. 



Not rare on the shaded slopes. 

 Bidens CONNATA Mk hi. Swamp Beggar-ticks. 



The typical form was rather common on shaded lower 

 slopes. 

 Chenopodium hybridum L. Maple-leaved Goosefoot. 



Quite common on lower wooded slopes. 

 Chenopodium boscianum Moq. Goosefoot. 



More common than the preceding species, and growing 

 with it, though usually selecting rather more open tracts in 

 the woods. 

 Aris^Ema triphyllum Torr. Indian Turnip. 



A few large fruiting specimens were found in rich soil 

 on the shaded lower slopes. 

 Panicum crus-galli muticum. Awnless Barnyard Grass. 



This awnless form of a species already reported, was 

 found in some numbers in a little swamp surrounding a 

 spring, and both the locality and the surroundings indi- 

 cated that it is native. The plants were very vigorous, 

 the culms reaching a half-inch in thickness at the base, 

 and six to seven feet in height.
