1. Pyrrhopappus carolinianus (Walt.) DC. False Dandelion. Map 

 2228. My only specimens are from a low, flat fallow field along Big Creek 

 about one and three fourths miles south of Wadesville, Posey County. In 

 this field are small areas where there is no vegetation, called by the land 

 owner salt spots. In this hard, white clay soil several specimens were 

 collected. 



This species was reported from White County by Heimlich. Since White 

 County has no habitats similar to the one in which I found my specimen, 

 I question the identification. White County is far north of the known 

 range of the species. If Heimlich found it, I believe it must have been 

 introduced. Andrews reported it from Monroe County, but since he pre- 

 served no specimen, and since the habitat is lacking and the place is north 

 of the range of the plant, the report is disregarded.

9605. CREPIS L. Hawkbeard 



Involucre pubescent; seed about 2.5 mm long 1. C. capillaris. 



Involucre glabrous; seed about 5 mm long 2. C. pulchra. 



1. CREPIS capillaris (L.) Wallr. Map 2229. I found this species well 

 established in Fairview Cemetery at Bluffton in 1923. In 1935 it had 

 spread, which shows that when it is established it will persist unless dili- 

 gent efforts are made to eradicate it. It would seem that constant mowing 

 in a cemetery would kill it, but it thrives nevertheless. It is plentiful in 

 the lawn of St. Mary's College, St. Joseph County.

2. CREPIS PULCHRA L. Map 2230. This species was found in Jefferson 

 County in 1934 by Miss Edna Banta. She reports that it is a common road- 

 side weed from Eagle Hollow east of Madison eastward along the River 

 Road to Morris Chapel, a mile east of Brooksburg, a distance of about 8 

 miles.
