 15. There is a specimen in the herbarium of the University of Wisconsin 

 ollected by Umbach in 1908 near Dune Park, Porter County, which I am 

 ef erring to this species. This specimen has the pubescent achenes and 

 he long, filiform peduncles of the lateral spikelets but the lobes of the 

 ypogynium are not acute or only scarcely so. Witmer Stone, in his "Flora 

 f Southern New Jersey," on page 284 says : "The width of the leaves and 

 iubescence of the achenes are characters which are very variable." The 

 ize of the achenes of our plants is about the same as those of S. reticu- 

 iris. While the achenes of typical S. reticularis are glabrous, sometimes 

 n achene is found which has a trace of pubescence which is a character 

 f S. setacea. 



This species is somewhat frequent on the moist or dry, sandy border of 

 lie west end of the second marsh from the north side of section 2 and on 

 hie east side of this section about 2i/ 2 miles southeast of Tefft, Jasper 

 bounty. It is closely associated with S. triglomerata Michx. and S. pauci- 

 lora var. caroliniana (Willd.) Wood. This is an interdunal marsh between 

 ather low sand hills which are covered with black oak. The marsh is 

 overed with Calamagrostis canadensis. Besides the Sclerias already named, 

 n the border of this marsh are found also Hypericum adpressum and 

 'anicum verrucosum. This marsh and others nearby are noted for the 

 umber of Coastal Plain plants found in them.
