190 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
distinguished from one another—but shall attend in future. 
If you please, let me send you specimens of my two broad 
leaved species from N. C. 
Kyllingia monocephala grows here at Bethlehem. On the grasses 
I can make no other observations—on account of my super- 
ficial knowledge—except mentioning which I should be glad 
to secure. l 
Scirpus pusillus Vahl—not known to me. 
caespitosus B. callosus Big.—do. 
subsquarrosus—do. 
spadiceus—do. 
Schoenus mariscoides. I have a grass from Georgia which I have 
arranged under this name which appears to be a congener of 
the Cladium Mariscus of Europe. 
` Rhynchospora fusca R. & S.—has this grass been really found in 
Am.? 
Dulichium canadense. —I have found a grass in appearance like 
D. canad. in the Lehigh Gap—Whether distinct enough to 
constitute a species I will not decide. 
Cyperus dentatus—unknown to me. 
Cyperus virens or one that I call so—& a very distinct species, is 
common here on the gravelly river shore. 
Cyperus flavicomis.—I am pretty sure that I have found it here. 
Spartina cynosuroides.—Can the tall ten foot high plant which 
I have found in the rich plains on the Muskingum be the same 
with that of your salt marshes? 
Paspalum stoloniferum.—I have specimens from European gardens 
& certainly never saw anything of the kind in Am. 
Milium effusum. I have found wild (it is not cultivated there at 
all) in North Carol. 
Aristida purpurascens I should be glad to see in order to ascertain 
whether certain suspicious ones I find belong to this species. — 
Your description does however not the least agree with speci- 
mens of racemosa derived from Muhlenberg. 
Trichodium montanum. Let me see. 
Agrostis stricta—I am glad you could not find it more than myself. 
—God knows what is meant. 
A. compressa—quite unknown.
