Vicia AMERICANA Muhl.; Willd. Sp. PI. 3: 1096. 1803.
No. 8449, collected April 20, near Lake Merced, in San
Mateo county, elevation 100 feet, in sandy soil, growing in a
mass among other vegetation, the stems two feet or more long.
It has always seemed strange to me that this species, originally
from Pennsylvania, should also be found on" the Pacific slope,
but the description in the Illustrated Flora shows little differ-
ence. Theieaf in our plant is narrowed, not “rounded at the
base,” and the calyx lobes are acute, not'blunt or nearly so, as
shown in the illustration. There may be floral differences, but
none of our descriptions mention the different parts of the flower,
so there is no basis for comparison.
