740 REPORT OF NEW JERSEY STATE MUSEUM. 



LACINARIA Hill.* 



Lacinaria spicata (L.)- Button Snakeroot. 



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

 Liatris spicata Knieskem 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 

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

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



Fl. — Mid- August to late September. 



Middle District.— Sqnan (C), New Egypt, Griffith's Swamp (C), Gloucester 

 Co., Mickleton (C). 



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



Lacinaria graminifoiia pilosa (Ait.). Hairy Button Snakeroot. 



Serratula pilosa Aiton, Hort. Kew. III. 138. 1789 [North America]. 

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

 Liatris graminifoiia dubia Knieskern 17. — Willis 29. — Britton 131. 

 Lacinaria graminifoiia 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 graminifoiia does 

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

 Britton's Catalogues prove to be erroneous. 



The wand-like spikes of 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 Augtist to late September. 



Middle District. — Clementon, Lindenwold. 



Pine Barrens. — Forked 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 hst was an error.
