Trifolium columbinuin Greene, Pittonia, 1: 4. 1887.
Habit of the preceding [olivaceum\ but rather smaller,
silky-pubescent throughout: leaflets with merely crenulate mar-
gins: flowering heads conical, more than an inch high and soine-
what less than an inch broad at base: calyx-tube less than a line
long, the filiform segments 5 lines, soft and densely silky plu-
mose throughout: corolla 11/2 lines long, vexillum white, wings
and keel deep purple: legume as in the last, but white-villous at
apex.
Both the above new clovers I found in May, 1886, growing
quite plentifully, by waysides and along the borders of fields,
near the village of Vacaville, hardly fifty miles north of San
Francisco. But T. olivaceum had been brought by Mrs. Curran,
from the opposite side of the Sacramento valley near Peuryn*
two years before. They are annuals with a striking resemblance
to T: arvense, completely hiding their small corollas within the
mass of elongated, silky calyx-segments. The heads are of a
rather bright olive green in the first species, and of a pale dove
color in the second; lienee the specific names.
