high; lowest leaves and base of stem hirsute or hispidulous, the plant 

 otherwise glabrous, glaucous : lower leaves spatulate, 24 in. long, sinuate- 

 pinnatifid or toothed, ciliate at least on the petioles; cauline ovate or 

 ovate-lanceolate, entire, clasping by a sagittate base: petals dull white or 

 greenish white, 2 3 lines long, little exceeding the sepals: pods erect, 

 usually even appressed to the stem, 2 4 in. long, less than a line wide, 

 straight, on pedicels 34 lines long: style short: seeds in 2 rows,narrowly 

 winged or wingless. Common. March May. 



2. A. hirsuta (L.), Scop. Seldom 2 ft. high, deep green, not glaucous, 

 hirsute throughout with a branched pubescence: cauline leaves oblong- 

 ovate or ovate lanceolate, sagittate or auricled at the clasping base, 

 coarsely toothed or entire: fl. small, white: pods very slender, erect. 

 Near Tocaloma, Biolelti. 



3. A. blepharophylla, Hook. & Arn. Stoutish, 412 in. high, deep 

 green, glabrous or sparsely pilose-pubescent: lower leaves obovate to 

 broadly spatulate, 1 2 in. long, entire or sinuate- toothed, strongly ciliate; 

 cauline oblong, sessile: sepals usually purplish: petals % in. long, rich 

 red-purple: pods 1% in. long, 1^ lines wide, suberect, beaked with a 

 short stout style : seeds in one row, a line wide. Kooky hills about San 

 Francisco. Feb. May. 



4. A. Breweri, Wats. Low, tufted perennial, rather rigid, 2 10 in 

 high, canescent with dense stellate pubescence: radical leaves spatulate, 1 in. 

 long, short-petioled, entire; cauline ovate-oblong, sessile, not sagittate: 

 petals rose-purple, 1 4 lines long: pods spreading or recurved, \}4.~^A 

 in. long, scarcely a line wide. Mt. Diablo Range, on rocks. Apr. June. 



5. A. Ludoyiciana (Nutt.), C. A. Mey. Nearly glabrous, branched 

 from the base and branches ascending, 610 in. long: leaves all pinnate- 

 ly parted into oblong or linear few-toothed or entire segments :Ji. small, 

 white: pods spreading on short pedicels, flat, rather broad-linear, 1 in. 

 long: seeds orbicular, wing-margined. Banks of the lower San Joaquin. 



6. STREPTANTHUS, Nutt. Mostly annuals, the few branches 

 loosely racemose throughout. Leaves pinnatifid or toothed, rarely 

 entire, except the cauline, and these mostly sagittate and clasping. 

 Calyx whitish or colored, open or closed, often irregular, 2 or all of 

 sepals saccate at base. Petals with broad channelled claw and (in our 

 species) a narrow usually more or less undulate limb. Stamens either 

 tetradynamous or in 3 unequal pairs, the uppermost pair often with- fila- 

 ments united; anthers elongated, sagittate at base, curved in age. Pod 

 from flat and thin to subterete; valves 1-nerved or rarely carinate. 

 Seeds more or less flattened, margined or marginless.
