usually wanting; peduncle and calyx densely cottony-villose, 
_ much less so in age, the outer surface of the sepals loosely pilose- 
pubescent, the reflected brownish-purple segments somewhat shin- 
ing and minutely puberulent with dull purple hairs and faintly 
parallel-veined ; inflexed tips of the sepals in the mature bud ex- 
tending only half-way to tip of column; interior of tube white 
or greenish-white below the rim, the disk surrounded by a purple 
band as in Canadense ; exterior of flower white to greenish-purple, 
the hexagonal base with prominent rounded angles and interven- 
ing depressions ; surface of ovary plane or nearly so; column 
slender, columnar, longer than in Canadense,4—7 mm. long, strongly 
grooved to receive the longer series of stamens, the stigmas green- 
ish and purple, rather smaller than in Cavadense and often merely 
granulose ; stamens deeper purple than in Caxadeuse with shorter 
anthers, the filaments slightly longer and closer to the column, 
their tips shorter and less attenuate, often less than half the length 
of the anther. (Plate 317.) 
Rich low woods along streams or river valleys, often forming 
extensive beds; more rarely in upland woods; flowering at the 
same time as A. Canadense. Southeastern New York, and doubt- 
_ less Connecticut, to Iowa, south to the mountains of North Caro- 
lina, Missouri and Kansas. 
Aside from the notable differences of the flowers which has 
already been emphasized, Asarum reflexum differs generally from 
A. Canadense in more slender habit, sparser pubescence of rather 
longer hairs, and more broadly reniform leaves. The plant is also 
much less aromatic. 
The typical form of the plant which occurs in rich woodland 
along the banks of streams and rivers is particularly characterized — 
by slender elongated rootst »cks loosely interlaced on and near the 
surface of the ground, long internodes, and broad leaf-blades with 
divergent sides and wide openly graduated sinus. The occasional 
form of drier upland woods is rather stouter and more pubescent 
with shorter internodes and rootstocks, the leaf-blades commonly 
suborbicular and more or less rounded at the apex, the sides par- 
allel or approaching rather than divergent and rounding into Or = 
even overlapping at the sinus, which is very wide at the insertion 
of the petiole ; the opening of the flower is nearly circular instead 
of more or less triangular as in the type.
