— This species apparently should stand between P. effusa, Dougl. (of which I have 
present access to no specimen for comparison) and P. Pennsylvanica, e. Hippiana. The 
flowering stems are 6 to 8 inches high, scape-like, hearing only a single well-formed leaf 
near the base, and beginning a little above to divide into the effuse, several times dichot- 
omous cyme. Stipules entire, or nearly so. Pedicels 13 inch long. Flowers rather 
smaller than in P, Pennsylvanica.

comoso.— Along Santa Fé Creek, and at the foot of hills, in sunny places; July. — 
Stems 6 inches high. Radical leaves 2 inches long, including the petiole: leaflets half 
an inch long; the surface soon smooth or nearly so; the lower clothed with long and
