A STATION FOR CROTON GLANDULOSUS IN NEW JERSEY. 



BAYAKD LONO. 



Some years ago, during an examination of the private herbarium 

 of Mr. W. If. Roper of Atco, Now Jersey, I came unexpectedly upon 

 local material of Croton glanduhsus L. 1 Mr. Roper was quite familiar 

 with the plant and informed nie that it occurred along the railroad 

 above Bishops Bridge — a flag-stop near Atco. This spot is along 

 the steam line of the Pennsylvania Railroad to Atlantic City, about 

 twenty miles out of Camden. 



Croton glandnhsvs is a tropical American species of sandy soils, 

 extending northward in the Mississippi valley to Iowa and through 

 the southeastern states to Virginia. In the northeastern United 

 States it is hest known historically, as one of the ballast-ground 

 plants formerly found about certain of the Atlantic seaports. In 

 Aubrey H. Smith's paper on "On Colonies of Plants Observed near 

 Philadelphia," 3 published in 1867, it is reported to have occurred 

 below the Navy Yard from 1864 to 180(5, being "more abundant in 

 the last of these years" — which is amply borne out by numerous 

 specimens dated 1866 contained in various herbaria. There are 

 collections from Kaighn's Point, Camden, New Jersey, opposite 

 Philadelphia, made in the same year, as well as in I860. It was ob- 

 tained in 1866 at Newcastle, Delaware, not very far below Phila- 

 delphia. A single plant only, however, was noted, according to the 

 label-data with the extant material in the Commons Herbarium, 

 and there is no evidence that the species occurred there subsequently.
