PLANTS OF SOUTHERNl NEW JERSEY. 553 



Limited to the valley of the upper Delaware, just entering 

 our limits at Bordentown, where it is reported in Britton's Cata- 

 logue on the authority of Mr. Stowell. 



Fl. — Early July to late July. Pr. — ^Early September into 

 October. 



Hypericum densiflorum Pursh. Shrubby St. John's-wort. 



Hypericum densiflorum Pursh, Fl. Am. Sept. 2>7^- 1814 [Virginia Mts.]. — 



Britton 67. — Keller and Brown 224. 

 Hypericum proMcum var. densiflorum Knieskem 8. — Willis 11. 

 Hypericum proliUcum Britton 67 (in part). 



Plentiful in damp spots in the Pine Barrens, rare and local in 

 the Middle district. 



H. proimcwm is reported in Britton's Catalogue, but I feel 

 convinced that all the coastal plain plants of New Jersey are 

 referable to H. densiflormn. Specimens from' three of the locali- 

 ties prove tO' belong to this species, and I have little doubt that 

 the records for Manchester, Freehold and Pemberton are based 

 on the same. There is some variation both in the size of the 

 flowers and density of the inflorescence, but I have seen no speci- 

 mens at all referable to H. prolificum, as we have it in the Sus- 

 quehanna valley in Pennsylvania.* 



Fl. — Early July to early September. Fr. — Early October 

 through autumsn. 



Middle District. — Shark River, Pt. Pleasant, New Egypt, Linden wold. 



Pine Barrens. — Toms River, Island Hts., Cassville, Woodmansie, Hanover, 

 Browns Mills, Chatsworth, Speedwell (S), Pasadena, Parkdale, Tuckerton, 

 Bear Swamp, Kenilworth, Clementon, Ballengers Mill, Braddocks Mill, Taun- 

 ton, Sicklerville, Winslow Jnc, Winslow (S), Folsom, Eighth St. (T), Ham- 

 monion, Pleasant Mills, Egg Harbor City, Mays Landing, Weymouth, Wood- 

 bine, Millville. 



Hypericum adpressum Barton. Barton's St. John's-wort.f 



Hypericum adpressum Barton, Comp. Fl. Phila. II. 15. 1818 [Lansdowne, on 

 the Schuylk-ill, above Buck's Isl., Phila.].— WiUis 11.— Britton 67.— Keller 

 and Brown 224. 



* cf. Sargent Garden and Forest, 1890, 524. 



t Discovered by Wm. P. C. Barton (1786-1856), Professor of Botany at the 

 University of Pennsylvania, and author of the Compendium Florae Philadel- 

 phicae. Probably the first botanist of this vicinity to conduct weekly field 

 trips.
