FLOWERING PLANTS AM) FERXS OF INDIANA. 885 



VINCETOXICUM Walt. 



V. gonocarpos Walt. Large-leaved Angle-pod. 



(Gonolobus lewis macrophyllus Gray.) 

 In moist thickets in the southern part of the State. Herbarium 

 specimens are labelled •"southern Indiana.*' so no definite coun- 

 ties can be given. The collections were probably made in the 

 southwestern counties, the form having entered our flora from the 

 south rather than the east. 



V. gonocarpos l.evis (Michx.) Britton. 



(Gonolobus Icevis Michx.) 

 Along the banks of streams in rich, wet soils, in the southwest- 

 ern counties. Of sparing occurrence. 

 Gibson and Posey (Schneck). 



CONVOLVULACE.E Morning-glory Family. 



QUAMOCLIT Moench. 



Q. coccinea (L.) Moench. Cypress Vine. Indian Pink. 

 (Ipomcea Quamoclit L.) 



Escaped from gardens somewhat extensively in the southern 

 part of the State. It nowhere wanders far from its original sta- 

 tion, not leaving cultivated grounds, or those recently abandoned. 

 Apparently unable to maintain itself in the midst of the original 

 plants of the area. 



Flowers in July and August. 



Clark (Baird and Taylor); Gibson and Posey (Schneck); Jef- 

 ferson. 



IPOMCEA L. 



I. pandurata (L ) Meyer. Man-of-the-Earth. Wild Potato Vine. 



Abundant in sandy soils and cultivated fields in many parts of 

 the State. The trailing or climbing weak steins give little evi- 

 dence of the enormous fleshy root from which they spring. This 

 root habit makes it very difficult to exterminate when it has fairly 

 established itself and has given it a place among the worst weeds 

 in many localities. 



Flowering begins in May and continues through the summer. 



Tippecanoe (Cunningham); Jefferson and Kosciusko (Coulter); 

 Clark (Baird and Taylor); Dearborn (Collins); Gibson and Posey 

 (Schneck); Xoble (Van Gorder); Franklin (Meyncke); Jay, Dela- 

 ware, Eandolph. and Wayne (Phinney); Decatur (Ballard); 

 Fayette (Hessler): Vigo (Blatchley).
