62. Obolaria virginica L. Peunywort. 



Putnam Count}-, on a wooded hillside. The most northern locality 



previously reported in the State is Vigo County. (State Catalogue, p. 879.) 



63. Gonobolus leavis Michx. (Ampelinus alibidus (Nult) Britt.; Ensleniaa. ) 



Climbing Milkweed, 

 Hamilton and Tippecanoe counties. "Confined to the southern coun- 

 ties, its northern record being Vigo County." (State Catalogue, p. 884.) 

 Each of these stations is of interest, as they very materially extend the 

 range of this species in the State. The Hamilton County locality was in 

 an abandoned roadway which had in latter years become a fence row. 

 The soil is red clay and the locality about a mile from the river. The 

 plant maintained itself for a number of years and began to spread to the 

 adjacent fields. It was at last eradicated by the landowner. The vine is 

 abundant in the bottoms of the Wabash River near Lafayette, where it 

 is a bad weed in cornfields. This species is probably of wider distribu- 

 tion in the State than the recorded localities would indicate, as it is very 

 easily overlooked on account of the superficial resemblance of its leaves to 

 those of Ipomoea pandurata with which it grows. 



64. Maerocalyx nyctalea (L. ) Kuntze. 



Tippecanoe County. A clump of this plant was found near the bank 

 of the Wabash River near Lafayette. Previously recorded only from Vigo 

 and Knox counties. (State Catalogue, p. 893.)*

 Hamilton County. 



*67. Riiellia strepens micrantha (Engelm. & Gray) Britton. (R. s. cleistan- 

 tha A. Gray.) 

 Hamilton and Marion counties. This is the commonest form of this 

 species in the central part of the State. 



68. Lonicera sempervirens L. Honeysuckle. 



Tippecanoe County, on dry hillsides. Not previously reported "north 

 of Wayne County." (State Catalogue, p. !>44.)
