 Harm. Among the interesting lichens encountered in the bog was 

 Cladonia impexa. Harm. This seems to be the only known station 

 for this lichen in New Jersey. Growing on an island in the south 

 branch we found a quite large colony of Smilax laurifolia L. 



Among the barrens plants, the oaks are especially interesting 

 and numerous. Those identified were Quercus alba L. (White 

 Oak), Q. stellata Wang (Post O.), Q. prinoides Willd. (Scrub 

 Chestnut O.), Q. prinoides var. rufescens Rehder, Q. primoides 

 form with very small leaves, Q. montana Willd. (Chestnut O.), 

 Q. horealis Michx. f. var. maxima Ashe (Red O.), Q. coccinea 

 Muench. (Scarlet O.), Q. velutina Lam. (Black O.), Q. jalcata 

 Michx. (Q. rubra L.) (Spanish O.), Q. ilicijolia Wang. (Black 

 Scrub O.), Q. marilandica Muench. (Black Jack O.), and Q. phel- 

 los L. (Willow O.). As is usual where several species of oaks occur 

 together, a few hybrids were encountered. Of these, the cross be- 

 tween Q. ilicijolia Wang, and Q. marilandica Muench. (X Q- Brit- 

 toni W. T. Davis) was common. Single specimens only of the fol- 

 lowing were seen: Q. ilicijolia Wang. X Q- jalcata Michx., Q. alba 

 L- X Q- prinoides Willd. and Q. stellata Wang. X Q- prinoides 

 Willd. 



In all a total of some 228 species of plants were recognized.
