lacca americana. In both instances I found only a single specimen although 

 I made extended search for others. Clapp reported it from the barrens near 

 New Albany, and Barnes reported it from Jefferson County without com- 

 ment. The distribution of this species is erratic and observers do not seem 

 to understand what factors are involved. It has been reported from 15 

 counties in Ohio but northward it has not been reported until the Upper 

 Peninsula of Michigan is reached.

957. STENANTHIUM (Gray) Kunth 



Capsules reflexed at maturity, mostly 7-8 mm long; leaves mostly 6-10 mm wide; plant 

 flowering mostly in July 1. S. gramineum. 



Capsules erect at maturity, mostly 7-10 mm long; leaves mostly 10-16 mm wide; plant 

 flowering mostly in August 2. S. robustum. 



1. Stenanthium gramineum (Ker) Kunth. Map 628. This species is 

 local in Indiana and apparently so throughout its range. It is infrequent 

 in sandy soil for half a mile in an open, black and white oak woods on 

 the south side of the Tippecanoe River north of Rochester, Fulton County, 

 and I found one plant in a sandy prairie habitat a mile north of Rochester. 

 There is a small colony on a low, sandy, open black and white oak ridge 

 between swamps in section 12 about 2*4 miles southeast of Etna Green, 

 Kosciusko County. I found it to be frequent for a short distance in sandy 

 soil at the base of a white and black oak slope on the south side of a large 

 swamp about 3 miles northwest of Hoover, Cass County. In the same 

 colony I found a specimen of the next species. The remainder of my speci- 

 mens were found in similar habitats. I have several times transplanted it 

 to the open in neutral soil in our garden and it has lived for only a few 

 years.

2. Stenanthium robustum Wats. Map 629. I have only two specimens 

 from Indiana which I refer to this species. Data concerning this species 

 and the preceding one are meager ; some authors do not separate them and
