20 Rhodora [JANUARY 
and Hierochloe odorata and Phragmites communis were abundant here 
as elsewhere along the South Shore. 
It was of special interest to find some of these seashore plants 
extending inland. Prunus maritima fruited heavily this year in the 
gravelly soil it likes best. It extends inland to Halifax and Hanson, 
some ten miles, and is equally abundant in the Merrimac valley, 
35 miles from the sea. Lechea maritima has an even broader landward 
range, as I have observed it. Atriplex patula grew lustily on the 
Duxbury dump, two miles back from the coast, with numerous garden 
escapes. Salsola Kali flourished in a barnyard, as vigorous as its 
var. tenuifolia, but still rigid and prickly. Hudsonia tomentosa, 
Ammophila arenaria and Artemisia caudata also occurred away from 
the shore. 
As might be expected in one of the oldest Pilgrim settlements, I 
found many introduced plants, over 50 species. Most interesting of 
these was the English oak, Quercus Robur L. It has been set out for 
shade and ornament at Powder Point and elsewhere in the village, 
but at South Duxbury it has become thoroughly established and is 
rapidly spreading. In the triangle of wild land between the railroad 
and the old graveyard where Myles Standish lies buried I discovered 
a large number of these trees, of all sizes, with much fruit. So far 
as I know this tree has never become established elsewhere in America. 
It may be distinguished by its rosettes of round-lobed, crinkly-edged 
leaves, and its large pedicellate fruit, the acorn five times the height 
of the cup. Another very conspicuous introduced plant, from the 
West, Oxybaphus nyctagineus, was abundant and widely scattered 
over the settled part of the town. Other pilgrims from abroad were 
Artemisia Stelleriana, Populus alba, Berteroa incana, and Dianthus 
plumarius. There were but a few plants of the last growing in a 
railroad cut very near the John Alden house. 
I observed exactly 50 species of Gramineae, a:few of which deserve 
mention. Sporobolus asper was in perfect condition on Sept. 24, the 
dark spikelets fully developed, and well emerged from the upper 
sheath. Paspalum setaceum was easily distinguishable from P. Muh- 
_lenbergii by its hairy sheaths and bright blue-green foliage. I have 
also found these two at Halifax, Plymouth and West Barnstable. 
Aristida purpurascens and Calamagrostis cinnoides I found each at 
one place only. : Andropogon glomeratus was abundant in a wet 
meadow. Agrostis perennans here, as elsewhere, was a characteristic 
plant of the dry oak woods.
