September I, 1904; streetside in the town 1912. 
*ARTEMISIA PONTICA L. 
Casually persistent and spreading as a survival of cultivation, 
not seen in flower. It is more frequent on Martha’s Vineyard,

*ARTEMISIA STELLERIANA Bess, 
A characteristic plant of the sea beaches, mainly on the north 
side of the island, growing in dense confluent patches on the white 
sand beyond the reach of the tides; rarely seen away from the 
immediate shore, but becoming established in spots among the 
beach grass above the highest bluffs. Nearly in flower May 30, 
1909, June 7, 1911; earliest flowers June 17, 1910; past its height 
of bloom June 27, 1912; continuing to produce some flowering 
stems during the summer and sometimes into September. 
-ERECHTITES HIERACIFOLIA (L.) Raf. 
Very common, especially among the open groups of mixed 
woody and herbaceous vegetation that aré scattered over the 
‘plains, this being the first predominating plant that springs up 
after these growths have been laid waste by fires. It is even more 
abundant among the windrows of shore refuse back of the beaches 
around Sachacha Pond where it becomes unusually stout and 
hairy and develops much purplish coloring in its upper parts. 
- Plants a few inches high June 19, 1910, June 27, 1912; in full 
flower during September.
