 Phil. Mag. ii. 70 (1833), under Limnanthes, also Lmdl. Bot. Reg. t. 1673. 

 Glabrous throughout, 6 — 18 in. high : leaflets narrowly cuneiform, 

 incisely lobed or parted : peduncles 2 — 4 in. long : sepals lanceolate, 

 3^ — 13 in. long : petals yellow, % in. long, obovate, emarginate : achenes

 of the Sierra, in very very wet places. Apr. May. 



2. F. rosea, Greene. Hartw. in Benth. PI. Hartw. 301 (1849), under 

 Limnanthes. Very near the preceding, rather stouter ; leaf-lobes almost 

 linear ; petals broader, white, fading with a tinge of rose : achenes 

 broader, more coarsely and more sharply roughened. — Common in the 

 interior, along the lower Sacramento and San Joaquin, on moist subsaline 

 lowlands. Mar., Apr. 



3. F. alba, Greene. Hart-w.l.c., under Limnanthes. Smaller, relatively 

 stouter, but the stems only 2 — 5 in. long : leaf -segments short, broad, 

 3-lobed : young parts and calyx rather densely long-woolly : petals 

 white, little exceeding the calyx. — A very distinct species, belonging to 

 the upper Sacramento, thence ranging northward. 



6. OXALIS, Linaxus (Wood-Sokrel). Herbs with sour juice (con- 

 taining oxalic acid), alternate palmately 3-foliolate leaves and cymose or 

 umbellate regular 5-merous flowers. Sepals imbricate, distinct or slightly 

 coherent at base, persistent. Petals convolute, deciduous. Stamens 10, 

 more or less monadelphous, those opposite the petals longer than the 

 others. Ovary of 5 united carpels ; styles distinct. Fruit an ovoid or 

 columnar loculicidally dehiscent capsule ; the valves remaining attached 

 to the central axis ; cells 2 -several-seeded. Seeds pendulous, the testa 

 aril-like, at length splitting and becoming recurved.
