Jones’ Mill and Speedwell,’ with the date July 9, 1909. The other, 
my own 4273 from Winslow Junc., south along A. C. R. R., on Penny- 
pot Stream (branch of Great Egg Harbor River), June 23, 1910. 
This gives stations a little more than twenty miles apart, and on two 
of the larger rivers of N. J. All the localities are distinctly pine- 
barren. Probably our plant is another peculiar pine-barren form." 
“The habitat is quite characteristic. All five stations are similar. 
It might be called an open pine-barren marsh, scarcely ‘bog.’ It is 
the peculiar open area in the pines, supporting commonly only her- 
baceous vegetation and surrounded by thickets and woods, that occurs 
mostly along or in the vicinity of the bigger streams. It is not char- 
acteristically sphagnous and the vegetation is mostly rank. In spring 
it is generally quite flooded, but dries out during the summer. The 
Scirpus at Andrews was in a foot, or probably more, of water." 
One of the most interesting points in regard to this new Scirpus is, 
that by the Philadelphia botanists it is considered a very typical 
member of the Pine Barren flora, being confined in their region to a 
small area of Pine Barren country; and that it is as yet unknown 
elsewhere except along the Charles River in eastern Massachusetts. 
The latter region, with the adjacent valleys of the Neponset, Concord, 
Mystic, and other small rivers, marks nearly or quite the northeastern 
limit of many plants, local with us but by no means so rare in New 
Jersey,— Lilium superbum, Spiranthes Beckii, Sagina decumbens, 
Draba caroliniana, Cassia Chamaecrista, Crotalaria sagittalis, Polygala 
Nuttallii, Hex glabra, Rotala ramosior, Ludvigia sphaerocarpa, Pro- 
serpinaca pectinata, Hydrocotyle umbellata, Cuscuta arvensis, C. com- 
pacta, Lycopus rubellus, Eupatorium rotundifolium, E. aromaticum, 
Aster spectabilis, Coreopsis rosea, etc., etc.— and most of these species 
are found at scattered (or sometimes numerous) stations, chiefly 
on the Cretaceous or Tertiary sands and clays, in southern New Eng- 
land, on Long Island or on Staten Island. It is, then, reasonable 
to suppose that Scirpus Longit is to be classed with them as a member 
of the Pine Barren flora which extends, in somewhat reduced abun- 
dance, well beyond the southeastern Coastal Plain into the more 
sterile districts of coastwise New England.
