1913] Fernald € Wiegand,— Calamagrostis Pickeringii 135 
POTENTILLA FRUTICOSA L. was collected in a pasture at Pittsfield, 
on July 23, 1912, and in a pasture in Center Minot on August 14, 
1912. Before this time I had not seen the plant in any of the towns 
near Clinton. 
PRUNUS VIRGINIANA L., var. LEUCOCARPA Wats. This was growing 
beside a country road in West Minot. I collected on August 14, 1912. 
"The amber-colored fruit was entirely new to me. It has been known 
in' this locality for thirty years at least. 
PYcNANTHEMUM VIRGINIANUM (L.) Durand & Jackson. At a 
distance this had the appearance of a white aster. I collected it on 
August 27, 1912, in a field near woods one mile south of Clinton 
Village. This was an entirely new plant for this locality. 
UTRICULARIA. During the meeting of the Josselyn Botanical 
Society at Gardiner in 1912, while on a trip to Nahumkeag pond in 
Pittston, I found three Utriculariae. U. vulgaris, L. was growing 
in the shallow water at the west side of the pond. U. purpurea Walt. 
was found in a similar situation, though but a single plant. U. 
gibba L. was growing on small islands near the same shore. "These 
plants were about 3 cm. high. All three species were collected August 
9, 1912. 
WAKEFIELD, MASSACHUSETTS. 
CALAMAGROSTIS PICKERINGH Gray, var. debilis (Kearney) n. comb. 
C. breviseta debilis Kearney, U. S. Dept. Agric. Div. Agrost. Bull. xi. 
25 (1898). In Newfoundland we became very familiar with two pro- 
nounced tendencies of C. Pickeringii, one of rather coarse habit with 
Spikelets large (4-5 mm. long), a comparatively common plant; the 
other, the commonest grass of bogs and tundra, with often more 
slender habit and with spikelets small (2.8-3.6 mm. long). Examina- 
tion of the material in the Gray Herbarium, and especially of 'the 
specimens cited by Kearney, shows that the plant with larger spikelets 
is true C. Pickeringii (of which the type is in the Gray Herbarium), 
while the plant with smaller spikelets closely matches the duplicate 
type of C. breviseta debilis. 'The characters emphasized by Kearney, 
however: “Of softer texture; culms sometimes only 2 dm. high, very 
slender, less rigid, the uppermost internodes much elongated, usually 
twice as long as both sheath and blade; leaf-blades thinner and rather 
lax; panicle small (mostly 4 to 10 cm. long, about 1 cm. wide), con-
