﻿566 Bicknell: Ferns and flowering plants of Nantucket 



Gray. In full flower through September; precocious flowers are 

 frequent before the middle of August. 



An aster in full flower, collected by the Wauwinet road near 

 Norwood, is quite intermediate between this species, more espe- 

 cially var. elodes, and Aster dumosus, and has every appearance 

 of being a hybrid. 

 Aster concolor L. 



One of the conspicuous late flowering plants of the plains 

 and commons. It is not ordinarily densely massed in growth, 

 but at Hummock Pond along a bank of white sand close to the 

 ocean shore it was seen late in September outspread in an even 

 more continuous breadth of color than a bed of violets in spring. 

 First flowers September 8, 1904, September 15, 1907. It is also 

 a very common aster of Chappaquiddick Island where I have 

 seen it still in full flower as late as the middle of October. 



The pubescence of the early leafy shoots is remarkably dif- 

 ferent from the canescent investiture of the mature stems con- 

 sisting of silky-villous horizontally spreading hairs, some of them 

 4-5 mm. in length. The earlier leaves which are spreading, and 

 densely pilose and long ciliate, are, by a twist at the base, brought 

 into two opposite series along the stem with their surfaces in 

 lateral aspect instead of horizontal, after the manner of Lactuca 



Aster spectabilis Ait. 



Rather common towards Siasconset in open thickets of low 

 shrubbery in dry places; scarce in other parts of the island: 

 Wauwinet road less than two miles from the town; near the south 

 shore to the west of Miacomet Pond; north of Long Pond. In 

 full flower August 30, 1904; September 11, 1907. 

 Aster dumosus L. 



Perhaps the most common and generally distributed aster of 

 the island, most numerous in sandy soil in low grounds. In full 

 flower September 10, 1907. Forms having small heads with deep 

 lavender rays contrast markedly with other forms having larger 

 heads with the rays pure white. A form referable broadly to the 

 var. cordifolius (Michx.) T. & G., yet not the same as the 

 typical southern extreme of this plant, is occasional in pine barrens.
