382 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
and is in full flower. It has been carefully compared at the New 
York Botanical Garden, in conjunction with Dr. Britton, and 
agrees so closely with authentic material in the herbarium that 
although we feel some slight hesitancy in pronouncing it identical 
there seem to be no reasonable grounds for doubting its equivalency. 
The species has been grown in botanical gardens but is not in 
general cultivation, and how or when it came to be transported to 
Nantucket is hard to conjecture. Miss Gardner writes me that 
“it has grown for years in a neglected yard on Milk street and is 
occasionally found in old yards and lanes in the south part of the 
town.” 
*HAMAMELIS VIRGINIANA L. 
“Thicket opposite Bloomingdale,’”’ 1896, Mr. L. L. Dame, 
reported in a letter to Mrs. Owen, fide Mr. F. G. Floyd. Mr. 
Dame’s determination of this unmistakable shrub cannot be ques-

any other collector, it is perfectly at home in parts of Martha’s 
Vineyard. The only representative on Nantucket of the family

In the herbarium of the New York Botanical Garden is a 
specimen of this strawberry determined by Dr. Rydberg, which 
was collected at Siasconset June 8, 1900, by Miss M. A. Day 
(Plants of Nantucket, No. 9). 
*POTENTILLA RECTA L, 
Collected by Miss Gardner in waste ground on Prospect Hill, 
August 23, 1913, in flower and fruit. Mrs. Flynn writes me that 
she found it “quite abundant in the Catholic Cemetery where it 
was probably introduced in grass seed.”’ 
*FILIPENDULA ULMARIA (L.) Maxim. 
Found at Consue Spring, July 9, 1912, freshly in flower and 
forming part of a tall weedy growth, some of the plants being 
nearly six feet in height. 
Rosa, 
By a sort of routine and acquiescent view all the wild roses of 
Nantucket that are not Rosa carolina L. might seem to pass readily 
enough to Rosa virginiana Mill. Nevertheless it may easily be
