202 Rhodora [ OCTOBER 
Gratiola Virginiana, L. Wet place in a clearing, Sutton. Pre- 
viously reported from Lake Quinsigamond. 
Polygonum Muhlenbergii, Watson. Shallow water of Maanexit 
River, North Webster. Very local in the county. 
Polygonella articulata, Meisn. Roadside, Dudley. Apparently 
frequent in the towns of the southern border. 
Betula papyrifera, Marshall. Occasional in rich woods, Webster, 
Dudley. Not common in the southern towns of the county. 
Abies balsamea, Miller. Although supposed to be restricted to the 
northern towns of the county, small trees (not fruiting) occur in 
Webster and Dudley. 
Taxus Canadensis, Willd. Abundant in deep woods, Royalston. 
Previously reported from Worcester. 
* Scirpus subterminalis, 'Torr., var. terrestris, Paine. Abundant 
in a small pond in Dudley (altitude 540 feet), September 9, 1899. 
The pond is a part of a reservoir system, and, owing to a drought, its 
water had been largely drawn off. The conditions were thus favor- 
able for the development of this interesting form, which is not likely 
to persist. Previously reported only from Herkimer County, N. Y. 
* Rhynchospora alba, Vahl. Sandy shore of brook, Webster. 
From this and Mr. Harper's observations, the species seems to be 
rather frequent in southern Worcester County. 
* Cladium mariscoides, Torr. Sandy swamps, Webster. Re- 
ported from Brookfield and Sturbridge. | 
* Panicum filiforme, L. Sandy field, Oxford. Previously re- 
ported only from Brookfield.
