740 REPORT OF NEW JERSEY STATE MUSEUM. 



LACINARIA Hill.* 



Lacinaria spicata (L.)- Button Snakeroot. 



Serratula spicata Linnseus, Sp. PI. 819. 1753 [North America]. 

 Liatris spicata Knieskern 17. — Willis 29.^Britton 131. 

 Lacinaria spicata Keller and Brown 321. 



Frequent; open moist ground in the northern counties and 

 occasional in the Middle district within our limits. Rare on 

 the Coast strip. 



The statement in Keller and Brown's List that this species is 

 combion in the Pine Barrens is an error, as we have no record 

 from that district. The species of that region is the following. 



Pi. — Mid-August to late September. 



Middle Duinc*.— Squan (C), New Egypt, Griffith's Swamp (C), Gloucester 

 Co., Mickleton (C). 

 Coast Strip. — Bay Head, Pt. Pleasant (C), Manahawkin. 



Lacinaria graminifolia pllosa (Ait.). Hairy Button Snal<eroot. 



Serratula pilosa Alton, Hort. Kew. HI. 138. 1789 [North America]. 

 Liatris pilosa Pursh, Fl. Am. Sept. II. 508. 1814. 

 Liatris graminifolia dubia Knieskern 17. — ^Willis 29. — Britton 131. 

 Lacinaria graminifolia (pilosa Keller and Brown 321. 



Common in sandy ground in the Pine Barrens, Coast Strip 

 and Cape May peninsula, and locally in the Middle district in 

 so-called "Pine Barren islands." The true graminifolia does 

 not occur in the State, and the contrary statements in Willis' and 

 Britton's Catalogues prove to be erroneous. 



The wand-like spikes O'f purple blossoms of the Button Snake 

 root are tO' be seen on every hand in the Pine Barrens in late 

 summer and early autumn. The general resemblance to the 

 spikes of Aster concolor is rather striking. 



Fl. — Early August to late September. 



Middle District. — Clementon, Lindenwold. 



Pine Barrens.— Porktd River, Manchester, Brown's Mills (T), Whitings 

 (S), Jones' Mill (S), Speedwell (S), Taunton, Clementon, Atco, Atsion, 



* Lacinaria scariosa (Serratula scariosa Linn., Sp. PI. 818 — Virginia) is 

 recorded in Britton's Catalogue from Keyport and near Newfoundland "'evi- 

 dently rare." There are no specimens in the State herbarium, and I know 

 of no further evidence of the plant occurring in New Jersey. 



The record for Hammonton in Keller and Brown's list was an error.
