CATALOGUE OF PLANTS. F". 145 



In the above list there is one species almost peculiar, be- 

 ing known, so far as I am aware, at only one other locality. 

 The Box Huckleberry, Gaylussaccia trackycera, grows 

 abundantly in a small tract of about ten acres near New 

 Bloomfield. To this space it is, I believe, limited. Outside 

 the county it is found on the banks of Indian river, near 

 Hillsborough, Sussex county, Delaware, as reported by Hr. 

 A. Commons. It was described many years ago by Michaux, 

 from Virginia, (Winchester and Warm springs,) but has 

 been found there by no one since. 



It appears to be a lingering relic of the ancient flora of 

 the county, maintaining itself on the sterile hill-side of Che- 

 mung shale, but liable to be destroyed by cultivation at any 

 time. It is exceedingly plentiful, forming a perfect mat 

 over much of the ground, but its limits are sharply defined 

 without apparent cause.
