Convolvulus repens L. 



1. Convolvulus spithamaeus L. Map 1669. This species is variable in 

 the density of its pubescence, the shape of the leaves, and the length of 

 the stem. Generally in poor clay soil in bare places on open wooded 

 slopes and rarely in sandy soil in prairie habitats. 



N. S. to Man., southw. to Fla. and Ky. 



2. Convolvulus japonicus Thunb. Rose Convolvulus. Map 1670. 

 In moist waste places. Escaped from cultivation in Marion, Monroe, Put- 

 nam, and Tipton Counties.

3. Convolvulus sepium L. Hedge Bindweed. Map 1671. I was told 

 by a farmer who had lived in several places in Carroll County that this 

 species is known there to the farmers as gopher weed. It is a pernicious 

 weed. It prefers a moist alluvial soil. Frequent to common in cultivated 

 fields, along roadsides and railroads, and in waste places, fallow fields, and 

 open woodland along streams. 



N. S. to B. C, southw. to N. C, Kans., and N. Mex. 



3a. Convolvulus sepium var. fraterniflorus Mack. & Bush. (Convolvulus 

 fraterniflorus Mack. & Bush.) Map 1672. This variety is rare in Indiana 

 and has the habitat of the species. 



Ind. to Mont., southw. to Ark. and N. Mex. 



4. Convolvulus repens L. (Convolvulus sepium var. pubescens (Gray) 

 Fern.) Map 1673. In poor clay soil in fallow fields and on bare places 

 on open wooded slopes. Reported by Peattie for the Calumet District. 

 Rare. 



E. Que. to Fla., westw. at least to Ind. 



5. Convolvulus arvensis L. Field Bindweed. Map 1674. This 

 species is extremely variable in the shape of its leaves. We have specimens 

 with leaves varying from 5 to 35 mm in width. It is an obnoxious weed 

 wherever it is found. It is a plant mostly of waste places and along road- 

 sides, railroads, streets, and alleys.
