1917] Long,— Carex novae-angliae in Pennsylvania 97 
and Carex incomperta. There is a representation of Carex laevivaginata, 
C. projecta, and Dioscorea glauca. Even some very rare Pennsylvania 
plants had been obtained in several cases. Of that interesting sedge 
known as Rynchospora Smallii Britton, thus far found at only four 
localities in the state, the Pennsylvania assignment with the original 
description is based upon material collected by Porter in Chester 
County — a fact not very commonly known. 
It may not even be asserted with confidence that all of the additional 
native species, recognized in Porter’s time but not recorded by him 
from Pennsylvania, were entirely unknown to him from this: area. 
For, although he was one of the most acute and discriminating botan- 
ists of his day, like any other student he was not completely clear on 
every critical group. It is found, as a case in point, that although 
Carex Bicknellii, as a name, was well known to him and that he had 
excellent Pennsylvania material of it in his herbarium, it was confused 
with other allies of C. straminea in his Flora. But it is fairly certain 
that among real additions to the flora of the state, quite unknown to 
Porter, may be numbered such plants as Sporobolus uniflorus' and 
Rynchospora fusca! (discovered by Dr. Witmer Stone at Lake Bella 
Sylva in Sullivan County, August 29, 1903), Eleocharis Robbinsii ! 
(found by the late Charles S. Williamson, also at Lake Bella Sylva, 
August 18, 1908), Allium sibiricum? (apparently first detected by 
Mr. Perey Wilson on the Palisades of the Delaware River, in Pike 
County, opposite Sparrowbush, New York, May 30, 1902), Fim- 
bristylis puberula è (collected by the late Joel J. Carter, in his energetic 
explorations in Lancaster County, near Eldora Station, July 27, 1910). 
To this group may be added Carex novae-angliae upon the basis of 
several well authenticated stations in different portions of Penn- 
sylvania. 
For a Philadelphian, some of my most pleasant recollections, asso- 
ciated with a delightful week in June, 1907, on the Pocono Plateau, 
center about the finding of Labrador Tea, Twin-flower, Creeping 
Snowberry, Small Cranberry, and the like, but they might well be 
-coupled with a much more important discovery — had it been recog- 
nized at the time. With Porter’s Flora of Pennsylvania as a guide |

Stone’s The Plants of Southern New Jersey (Ann. Rep. N. J. State Mus., 1910, 110).
