122 Rhodora [JUNE 
Liriodendron Tulipifera, L. On August 6 I found numerous 
young trees of this species in Burrillville, R. I., along the east side 
of Wallum Pond, in woods of apparently about five years’ growth ; 
and a little further search revealed a few similar specimens just across 
the line in Douglas, Mass., which is probably very near the north- 
eastern limit of the species. 
Ranunculus Pennsylvanicus, L.f. Wet clayey soil, Southbridge, 
July 29. Credited only to Barre in the Worcester County flora. 
Adlumia cirrhosa, Raf. Shady, rocky woods, Southbridge, June 7. 
Dentaria diphylla, L. Northeast side of Shumway Hill, Stur- 
bridge, May 28. 
Alyssum calycinum, L. Several specimens in Oak Ridge Ceme- 
tery, Southbridge, June 6; only in ground which had been recently 
turned up and raked over; accompanied by a few specimens of its 
relative, Camelina sativa, Crantz. i 
Dalibarda repens, L. “Gulf Woods," Southbridge (elevation 500 
feet); quite abundant in certain spots. 
Potentilla palustris, L. Marshes and muddy banks of the Quaboag 
River, Brookfield and West Brookfield, May 30 (altitude 610 feet) ; 
also near Quinebaug River, Sturbridge, July 23 (altitude 575 feet). 
Poterium Canadense, L. Wet meadows, near Quaboag Lake and 
its tributaries, Brookfield and North Brookfield, June 18. No definite 
station is assigned to this plant in either edition of the Worcester 
County flora, but it seems to be very local in its distribution through- 
out New England. I have not seen it elsewhere in the county than 
in the valley of the Quaboag River. 
Acer spicatum, Lam. Several fine specimens on the steep south- 
west bank of the Quinebaug River in Sturbridge (altitude 590 feet). 
Previously reported from Princeton, where it is more abundant. Both 
in Sturbridge and on Mount Wachusett it is accompanied by Audus 
odoratus, L. ` 
Viola rotundifolia, L. Damp shady woods, in two or three local- 
ities in Southbridge, at altitudes ranging from 540 to 600 feet. 
Aralia quinquefolia, D. & P. Rich woods, Southbridge; about 
twenty specimens at one station. 
Moneses grandiflora, Salisb. A few specimens found June 26, 
1898, in rich woods near Hatchet Hill, Southbridge (altitude 800 
feet). 
Rhododendron viscosum, var. glaucum, Gray. Borders of cedar-
