Corema Conradii and its Localities. ^ 
By John H, Redfield. 
Referring to Dr. Gray's exhaustive paper in Chloris Boreali- 
Americana* for a full description and careful figures of this species, 
and for an account of its morphological relations, the object of this 
article is simply to place on record such facts connected with its 
known localities and environment as may tend to elucidate the past 
history of a plant now so sparsely represented in the existing flora. 
While its near relative, Empetrum nigrum^ abundantly clothes the 
mountain heights and colder regions of the northern hemisphere, 
our Corema is restricted to very limited spaces in widely separated 
localities, in the district extending from New Foundland to New 
jersey. Having been favored with opportunities to examine the 
principal known localities within our own limits, my notes will follow, 
as nearly as may be, the order of their discovery. 
I. iSfew Jersey Pine Barrens. — It is said to have been first dis- 
covered by Prof. Solomon W. Conrad as early as 1831 near Pember- 
ton Mills, about ten miles from Burlington, N. J., and a fragment so 
ticketed (with a ?) is in the herbarium of the Philadelphia Acad- 
^niy. Soon after, Rafinesque collected it at Cedar Bridge, Mon- 
niouth Co., about twenty-two miles south-east of Pemberton. This 
locality was visited about 1833 by Dr. Torrey, who published the 
first description of the plant under the name of Empetrum Conradii, 
in Annals of N. Y. Lyceum of Nat. Hist, iv., 83. In April, 1869, 
in company with the late Charles F. Parker, I made some examina- 
tion of the vicinity of Pemberton and also visited Cedar Bridge in 
search of the plant. The encroachment of cultivation near the 
former place discouraged search, but at Cedar Bridge the localities 
jvhich Dr. Torrey in his paper has so carefully indicated were readily 
Identified. But no trace of the plant was seen either at these points 
pT- elsewhere during a search of some hours. Dr. Torrey described 
It as growing in a few patches "in the pure white sand of that re- 
gion." These places, as I now remember them, were quite bare of 
vegetation at that early spring season, but the prevailing tree growth 
^/ all that region is a very stunted form of Pinus rigida. At the 
tune of Rafinesque's and Torrey*s visits, Cedar Bridge v/as an inn for 
^»e accommodation of the limited summer travel of that period by 
stage-coach between Philadelphia and Barnegat Bay. Now alas, an 
<>cca6ional clam-wagon is the only visitant, and as I remember the
