214 POLYGALACEAE. 



1. F. douglasii Baill. Meadow Foam. Branching from the base and 

 spreading, the branches <» to L4 in. Long; lierbage yellowish green, Bucculent, 

 glabrous; Leaves pinnately divided, the divisions 3 to mostly 9 and incisely 

 lobed or parted, the lobes linear, acute; peduncles at length 2 to 4 in. long; 

 sepals lanceolate, •"> to I linos long, y.> the length of the petals; petals white 

 (<»r occasionally roseate), yellowish at base, obovate-cuneate, a U-shaped 

 band of hairs on the claw; nutlets smooth to strongly tubereulate, about 2 

 lines in diameter. — (Limnanthes douglasii R. Br.) 



Low ground in or near shallow water, forming large patches which color in 

 Apr. the valley levels in the Coast Ranges. Its beauty in white and yellow 

 nearly as pleasing as that of blue in Nemophila menziesii. Cultivated in Eng- 

 land as a honey-bee plant. 



F. rosea Greene. Petals whitish with longitudinal rose-colored lines. — Sac- 

 ramento A^alley: Willows, W. L. J., 1899. F. alba Greene. Nutlets promi- 

 nently rugose tubereulate. — Sierra Nevada. 



POLYGALACEAE. Polygala Family. 



Ours perennial herbs or somewhat suffrutescent plants with alternate simple 

 leaves and no stipules. Flowers in terminal racemes, irregular and resembling 

 the papilionaceous flowers of Leguminosae, but not like them in structure. 

 Stamens (in ours) monadelphous. Ovary simple, superior. 



1. POLYGALA L. Milkwort. 



Stems often with milky juice. Sepals 5, thin, the two lower and the upper 

 keeled one of about the same size, the two lateral much larger, colored, and 

 projecting like the wings of a pea-flower. Petals 3, united at base; middle 

 petal hooded above and often beaked or crested, enclosing the stamens and 

 style. Stamens 8, monadelphous, the tube open on one side and adnate to the 

 base of the petals. Ovary 2-celled with one ovule in each cell; style long, 

 curved. Capsule with thin walls, flattened contrary to the partition, rounded 

 and often notched above, dehiscing loculicidally at the margin. Seeds with a 

 conspicuous caruncle. (Polus, much, and gala, milk, an ancient Greek name for 

 some shrub used as a stimulant.) 



1. P. calif ornica Nutt. Stems many from the branching crown of a 

 cord-like deeply descending perennial root, mostly simple, 3 to 8 in. high; 

 Leaves oblong- or elliptic-ovate, % to iy 2 i n - ^°T\g, distinctly petioled; flowers 

 of two sorts: — those near the root apetalous and developing most of the fruit; 

 those of the terminal racemes with rose-purple corolla 5 or 6 lines long, the 

 petals more or loss pubescent, at least inside or on the margin, the sepals 

 glabrous, with the shorter ones 2 to 3 lines long; capsule broadly elliptical, 

 glabrous, 3 lines long; caruncle of the seed wrinkled and bladdery. 



Wooded or brush-covered slopes in the (oast Ranges from Santa Barbara 

 to Marin Co. and the Napa Range and northward to Oregon. Not reported 

 from the inner Coast Range. May. 



P. coKNiTA Kell. of the Sierra Nevada, may be distinguished by its green- 

 ish white flowers and densely tonientose sepals. 



EUPHORBIACEAE. Spurge Family. 

 ()nr herbs, or one species somewhat Buffrutescent. Leaves simple, stipulate 



01 exstipulate. flowers (in ours) monoecious, always apetalous. often naked, 

 -. ' .. destitute Of calyx as well, sometimes exceedingly reduced and enclosed 

 in a calyi like Involucre. Stamens 1 to many. Ovary superior, 3 or 1-celled.
