380 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
*VACCARIA VACCARIA (L.) Britton. 
Vaccaria vulgaris Host. 
In abundance in a grain field at Quidnet, July 21, 1910, in full 
flower, Miss Gardner; weedy yard on North Water Street, June 27, 
1910, first flowers; waste ground at Surfside. 
*DIANTHUS PLUMARIUS L. 
Scattered through the grass of a bank on Grove Lane, doubtless 
an escape from an adjoining cemetery; in full flower June 21, 1910. 
On Chappaquiddick Island it is thoroughly established at one 
locality, forming an uneven turf of dense cushion-like tufts. 
*AQUILEGIA VULGARIS L. 
A waif in waste ground on Prospect Hill, September 22, 1913, 
herbarium of Miss Grace Brown Gardner. 
*THALICTRUM DASYCARPUM Fisch. & Lall. 
Little Neck, in low grounds, two clusters, the tallest plants 
fully six feet high, just in bloom June 22, 1910; bank near Watt’s 
Run, in full flower July 11, 1912, much less mature than T. revo- 
lutum DC. which grew near by. Apparently not before reported 
from New England. Specimens collected are perfectly typical and 
agree closely with authentic material from the western states. 
*PAPAVER SOMNIFERUM L. 
Rubbish dump on Prospect Hill, August 13, 1915, in full 
flower, herbarium of Miss Grace Brown Gardner; waste place, 
1895, Mrs. Nellie F. Flynn. 
*PAPAVER RHOEAs L. 
At the same locality as the above July 14, 1915, in full flower, 
herbarium of Miss Grace Brown Gardner. 
*ARGEMONE MEXICANA L. 
West Silver Street, July 15, 1910, with immature fruit, herb- 
arium of Miss Grace Brown Gardner. 
LEPIDIUM NEGLECTUM Thellung. 
This little-recognized peppergrass, earlier recorded in this 
list, but with a mark of interrogation, may now be definitely 
added to the Nantucket flora. A single plant in flower and fruit 
was found in a weedy yard on North Water Street, June 7, 1910, 
and four well-fruited plants in an old chicken paddock at Surfside, 
July 9, 1912. ;
