Panicum aciculare Desv. Bristling Panic Grass. 



Panicum aciculare "Desv" Poir, in Lamark Encycl. Suppl. 4 : 274. 1816 

 [S. E. United States]. 



Dry sandy ground in the southern part of the Cape May 

 peninsula, where it reaches the northern limit of its range. 

 First found in the State by the writer on June 30, 1909, near 

 Cold Spring. 



Fl. — Late June to late September. 



Cape May.— Cold Spring (S), Bennett, Fishing Creek (OHB). 



Panicum angustifoiium Ell. Narrow-leaved Panic Grass. 



Panicum angustifoiium Elliot, Hot. S. C. and Ga. I.: 129. 1816 [Florida]. 



Dry sandy ground in the southern part of the Cape May 

 peninsula, where it was discovered by Mr. O. H. Brown, Septem- 

 ber, 1909, extending the range north from Frankford, Delaware. 

 The specimen labelled from "the Schuylkill River below Reading, 

 Pa.," in the Philadelphia Academy Herbarium, while undoubt- 

 edly this species must have been mislabeled or introduced at that 

 station, as the locality is so completely out of its proper habitat. 

 Its chance introduction by canal boats is easily possible. 



Fl. — Late June to late September (probably). 



Cape May. — Green Creek. 



Panicum dichotomum L. Forked Panic Grass. 

 PI. IX., Fig. I. 

 Panicum dichotovium Linnceus, Sp. PL 58. 1753 [Virginia]. — Britton 280. 



A species of dry woodland not particularly abundant in our 

 region, but probably more characteristic of the Middle district 

 than of the Pine Barrens. In the latter it is found mostly along 

 the cleared strip of ground bordering the railroads from which 

 the undergrowth is constantly cut away as a precaution against 

 the spread of forest fires, and where various dry ground Pani- 

 cums flourish luxuriantly. That some of them owe their presence 

 to the railroads I have little doubt. 



Fl. — Early June to mid-July. 



Middle District.— MicklcXon, Sicklerville (S), Yorktown (S). 

 Pine Barrens. — Lakehurst, Pancoast (S). 

 Cape May. — Court House.
