subrotundatis brevissime petiolatis, oblongo-lanceolatis acutis.” 1 
This description would hardly have been given for the median leaves 
of the northeastern plant, which, as stated, are conspicuously cordate; 
and the plant is therefore here proposed as a new variety of E. glandu- 
losum. 
The other unique variant from the Gulf of St. Lawrence region is 
the plant of Brion Island, the outermost of the Magdalen Islands. 
In this variation the leaves are very unlike those of the variety just 
discussed as also the other described varieties, in all of which the leaves 
taper to an acute to acuminate apex. In the Brion Island plant, how- 
ever, the median leaves are elliptic-oblong to oblong-lanceolate and 
rounded at summit; but in its essential characters, of seeds, pubescence, 
and habit the plant belongs with E. glandulosum and E. adenocaulon. 
Briefly summarized the varieties of E. glandulosum may be char- 
acterized as follows: 
A. Flowers 6-9 mm. long: leaves crowded, not conspicuously decreasing 
in size into the crowded inflorescence................ Var. typicum. 
A. Flowers 4-8 mm. long: leaves remote, conspicuously decreasing in size 
into the loose and open inflorescence. 
B. Median cauline leaves cordate-attenuate, ovate, conspicuously cordate 
RS oe, Sa a ee Oe eee Var. cardiophyllum. 
B. Median leaves ovate-lanceolate to narrowly lanceolate or oblong, 
rounded, barely subcordate or narrowed at base. C. 
C. Leaves firm, rounded or barely subcordate at base, with very short 
pan stems (except in dwarf plants) freely branching, up to 1.3 m. 
gh. D. 
D. Leaves narrowly ovate to lanceolate, acuminate or at least acutish. 
Median leaves narrowly ovate or ovate-lanceolate. 
Var. adenocaulon. 
Median leaves elongate-lanceolate........... Var. occidentale. 
D. Leaves elliptic-oblong to oblong-lanceolate, rounded at summit. 
Var. brionense. 
C. Leaves thin and rather flaccid, tapering at base to the rather slender 
petiole: stems simple to slightly branching, 0.2-3 (rarely —4.5) dm.
