﻿550 Bicknell: Ferns and flowering plants of Nantucket 



elsewhere over the island. First flowers May 30, 1909, June 3, 

 191 1, June 7, 1908, June 15, 1910, continuing in bloom through 

 September. 



Much of the fall dandelion of Nantucket is the var. pratensis 

 Koch, which, in its most strongly developed form having large 

 flowers with nigrescent-lanate involucres, appears quite like a 

 distinct species. Notwithstanding its abundance on Nantucket, 

 Apargia autumnalis is a very scarce plant on Martha's Vineyard, 

 occurring only sparingly at a few far separated stations. The 

 var. pratensis seems to have made its appearance only on a few 

 lawns at Oak Bluffs and Vineyard Haven not far from where the 

 Nantucket boats make their landings. 



* Tragopogon pratensis L. 



Established in grassy lots on Main Street and on Milk Street 

 straying out along the thoroughfares. Collected by Mrs, Flynn 

 in 1895. First flowers June 3, 1909 ; still some flowers July 6, 1912. 

 Leontodon Taraxacum L. 



Taraxacum officinale Weber. 



Taraxacum Dens-leonis Desf . 



Apparently not a very common plant on Nantucket, and 

 certainly not there the abundant weed we are ordinarily accus- 

 tomed to regard it. Observed in flower from May until September.

Taraxacum erythrospermum Andrz.

 on the north side of the town. Collected by Mrs. Flynn south 

 of the town in 1904. Freshly in bloom July 4, 1912 ; in full flower 

 September 10, 1909.
