1922] Fernald,—Notes on the Flora of Nova Scotia 167 
J. MARGINATUS Rostk. New stations eastward to Annapolis and 
eastern Shelburne Cos. 
LoPHiOLA AMERICANA (Pursh) Wood. L. septentrionalis Fernald, 
Ruopoma, xxii. 243 (1922). LUNENBURG Co.: sphagnous boggy 
swale bordering Fancy Lake, near Conquerall. 
At this station the large, freely stoloniferous and subcespitose 
plants at the quaking margin of the lake are strikingly similar to the 
original L. septentrionalis from Digby Neck; but farther back, on 
drier knolls, the plants are small, with solitary stems, short pedicels 
and denser lanate tomentum, quite like the typical plant of New 
Jersey. Study of this material shows that the seed- and capsule- 
characters, which were exhibited by the Digby Neck material, break 
down, and that L. septentrionalis is not specifically separable from L. 
americana of the New Jersey pine barrens. 
**SISYRINCHIUM INTERMEDIUM Bicknell. Various colonies seem to 
belong to S. intermedium. The plants are all sterile and there still 
remains doubt as to whether S. intermedium is a true species. Our 
collections are from YARMOUTH Co.: border of spruce swamp, Mark- 
land (Cape Forchu); dry fields and clearings near St. John (Wilson) 
Lake. ANNaPorr Co.: thin open humus on North Mt., Belle Isle. 
S. ATLANTICUM Bicknell. Eastward to Annapolis and Lunenburg 
Cos. 
HABENARIA FLAVA (L.) Spreng. Several new stations, all in the 
valley of the Tusket, Yarmouth Co., north to Parr Lake and east to 
Canoe Lake. 
H. oBrUsATA (Pursh) Richardson. Very rare in the western 
Counties. ANNAPOLIS Co.: mossy woods, North Mt., Belle Isle. 
YARMOUTH Co.: mossy spruce woods, Greenville. 
H. wacnoPHnvrLLA Goldie. Dıcsy Co.: old mixed woods near 
Cedar Lake, New Tusket. 
SPIRANTHES CERNUA (L.) Richard, var. ocHmoLEvcA (Rydb.) 
Ames. Characteristic of the dryest of siliceous barrens. Additional 
stations are, for YARMOUTH Co.: gravelly railroad-bank, Belleville. 
SHELBURNE Co.: abundant on dry sandy Corema-heath, Hope’s Lot 
Barrens, Clyde River; common on dry sandy Corema-barrens north of 
Jordan Falls. 
Salix viminalis L. Naturalized in roadside thicket, Hassett, 
Digby Co. 
OsTRYA VIRGINIANA (Mill) K. Koch. Yarmoutru Co.: wooded 
shore of Parr Lake; tree with remarkably coriaceous foliage. 
THE VARIETIES OF BETULA LUTEA.—In 1904 Dr. Britton, by des- 
cribing Betula alleghaniensis,' called attention to the fact that we 
have two fairly marked trends of the Yellow Birch which had hither-
