Hybrid Oaks on Staten Island.— hx^Xwxx Hollick and W. T. Davis. 



(Proc. Nat Sci. Ass'n of S. L, Sept. 8th, 1888.) 



The discovery is reported, at Tottenville, Staten Island, of a

 palustris, Q. tinctoria, or Q. coccinea. From its position as one oi 

 a series of these peculiar forms the authors conclude that Q. 

 heterophylla is plainly a hybrid.
