244 ONAGRACEAE. 



Petals 4, obovate-cuneiform, sessile, 2-lobed. Stamens 8, 

 all perfect, unequal; filaments slender, naked at base; 

 anthers oblong, fixed near the base. Ovary 4-celled, 

 several-ovuled ; stigma-lobes short, somewhat cuneate. 

 Capsule membranous, ovate-oblong to linear, nearly 

 terete, acute, dehiscent at the base. Seeds in 1 row in 

 each cell, naked and smooth. 



1. B. glabella (Nutt.) Walp. Usually much-branched, the 

 branches decumbent or ascending, bluish green, densely soft-villous 

 to glabrous; leaves about 12 mm. long or more, ovate-lanceolate, 

 acute, serrulate, the upper similar; flowers in a terminal cluster and a 

 few shorter lateral spikes, also occasionally in the lower axils, shorter 

 than the subtending leaves; petals about 2 mm. long, violet; capsules 

 rather slender, nearly straight, usually acute, about 7 mm. long, 

 subterete, with 4 broad nerves or laterally somewhat 2-keeled, 

 loculicidal; seeds about 6 in each cell, subfusiform, about 0.35 mm. 

 broad, 1 mm. long. 



Low ground. Santa Monica; Mesmer; San Diego. July- 

 October. 



5. CLARKIA Pursh. 



Erect sparingly branched annuals with alternate 

 petiolate leaves, and racemose or spicate flowers nodding 

 in the bud. Calyx- tube more or less prolonged above the 

 ovary, deciduous. Petals 4, clawed, often lobed or cleft. 

 Stamens normally 8, those opposite the petals often 

 sterile, rudimentary or wanting; anthers oblong or 

 linear, fixed by the base. Ovary 4-celled; style elon- 

 gated; stigma 4-lobed, the lobes spreading. Capsule 

 linear, alternate above, coriaceous, straight or somewhat 

 curved, 4-angled, 4-valved to the middle. Seeds angled 

 or margined. 



1. C. elegans Dougl. Glabrous or somewhat puberulent, 

 glaucous, 3-15 dm. high, simple or somewhat branched, rather 

 stout and rigid; leaves broadly ovate to linear, repand-dentate; 

 petals entire, the rhomboidal limb about equaling the linear claw; 

 filaments all perfect, with a densely hairy scale on each side at base; 

 capsule 1-2 cm. long, stout, sessile, 4-angled, somewhat curved, 

 often hairy. 



Frequent in the chaparral belt, especially toward the coast, 

 extending south to San Luis Rey River. 



2. C. rhomboidia Dougl. Puberulent or glabrous, 3-10 dm. 

 high, rather slender, branching above; leaves thin, entire, oblong- 

 lanceolate or oblong-ovate, 2,5-5 cm. long; blade of petal rhom- 

 boidal, the claw short, broad, often toothed; stamens all perfect, the 

 filaments with hairy white scales at base; capsules pedicellate, 16- 

 24 mm. long, 4-angled, glabrous, curved near the base. 



Frequent in the pine belt of all our mountains.
