1910] Rehder,— A new hybrid Cornus 121 
quitoes and overlook the other discomforts of botanizing in a muddy 
and oozy district. U 
The half-day at Winnegance proved a brilliant finish for our outing 
in Maine, but as we look back over the entire summer, to the Washing- 
ton County coast, the Aroostook and Meduxnekeag Valleys, and 
Caribou Bog, we feel that we did well to visit these regions, for besides 
what is here related we made profitable studies on a score or more of 
taxonomic problems, some of which are already worked out, others 
awaiting further study. We also did what we could to verify the 
accounts formerly given of the vegetation of eastern Maine; and, 
though * X" seems from his over-enthusiastic language to have been a 
possible forerunner of the Maine coast land-boomer, his estimate was 
perhaps no more inaccurate than that of William Oakes. At any rate, 
if Oakes’s condemnation of the State of Maine has not already been 
proved too sweeping, we feel that the above notes and those which 
follow in more compact form are evidence that he erred in judgment 
when, in 1828, he wrote to Robbins that he was * convinced that no 
great accessions to the N. E. Flora, and of absolutely new plants hardly 
any, are to be expected from the State of Maine."

A NEW HYBRID CORNUS (CORNUS RUGOSA X 
STOLONIFERA). 
ALFRED REHDER. 
IN the summer of 1906 a specimen was received at the Arnold 
Arboretum of a Cornus collected by Mr. B. H. Slavin in Seneca Park, 
Rochester, New York, and accompanied by a note saving that it 
seemed to be different from Cornus stolonifera. A plant sent to the 
Arboretum in the spring of 1908 flowered and fruited last year, which 
gave me the opportunity to study also living material. I arrived at the 
conclusion that this dogwood could hardly be anything else than a
