Convolvulaceae of Indiana 279 



8. Convolvulus sepium. 

 Figs. 18 & 19. 



Convolvulus sepiti))i L., Sp. 153. 1753. 



Plant smooth or slightly hairy; peduncles equal to or longer than 

 the petioles and only one in each axil. 



Common throughout the State in moist situations. 



Specimens examined: — Allen Co. (Deam 1,359) ; Brown Co. (Deam 

 11,200); Floyd Co. (Deam 37,203); Hamilton Co. (Mrs. Deam 8,711);

 in part with Ipomoea lacunosa) ; Perry Co. (Deam 37,388A) ; Putnam 

 Co. (Grimes 646; McDougall in 1888; Yuncker l,29i) ; Pupley Co. (Deam

 Co. (Deam 37,593); Wells Co. (Deam in 1901 and in 1903). 



9. Convolvulus fraterniflorus. 

 Figs. 20 & 21. 



Convolvulus fraierniflorus Mackenzie & Bush, Rept. Mo. Bot. Garden 



16:104. 1905. 



Plants commonly hairy; peduncles ordinarily two or more in each 

 axil, mostly shorter than the petioles; bracts sparingly hairy. 



Mackenzie and Bush differentiated this species from Convolvulus 

 sepium chiefly on the following characters: Plant jmbescent; peduncles 

 angled and winged, ordinarily more than one in each axil and com- 

 monly shorter than the petioles; floral bracts cordate. This combination 

 of characters is not at all constant in our Indiana specimens. The speci- 

 mens here considered as being this species were chosen mainly on the 

 number and length of the peduncles. It is believed that a study of a 

 larger number of specim.ens collected from a more extended range would 

 show that this species is at the most worthy of but varietal distinction. 



In moist situations. 



Specimens examined: Clay Co. (Deam 37,782) ; Greene Co. (Deam 

 37,773); Hancock Co. (Mrs. Deam 9,073; Deam 37,840); Knox Co. 

 (Deam 17,059 A). 



10. Convolvulus repens. 



Figs. 26 & 27. 



Convolvulus repens L., Sp. PI. 153. 1753. 



Plants trailing, densely hairy; petioles mostly more than one-fourth 

 as long as the blade; basal lobes of the leaves rounded; peduncles ex- 

 ceeding the petioles; bracts mostly cordate. 



This species may be confused with some specimens of Convolvulus 

 spithamaeus showing a tendency to twine, but it differs mainly in the 

 degree of pubescence, length of plant and of petioles and in the shape 

 of the leaves and bracts.
