P. Californica (Nutt.! mss.): “carpels 3, glabrous; leaves smooth on both sides (not glaucous), ternate; leaflets broadly cuneate, nearly twice 3-cleft; laciniæ oblong-lanceolate, acute.
“Margins of bushy plains, and in the valleys of the mountains, in the vicinity St. Barbara, Upper California. March-April.—Differs from the preceding in the smaller, less divided and broader leaves, which are deep green on both sides; and the leaflets bifid or trifid, never pinnatifid. Sepals never expanding, one, and sometimes two of the outer ones ending in a small trifid leaf. Petals small, scarcely exceeding the length of the calyx, deep blood-red. Seeds large, light brown, cylindrical-ovoid.” Nutt.
