HYDROPHYLLACEAE. 295 



other plants for support by means of the prickles; leaves deeply 

 pinnatifid, the lobes somewhat reflexed; petioles winged, clasping 

 at base; flowers in few-flowered racemes at the ends of the branches; 

 corolla 12-25 mm. broad, purplish violet; scales triangular, covering 

 the base of the filaments; capsule globose; seeds 4, globular, favose- 

 reticulated. 



Common on shady slopes throughout our range below 3000 feet. 

 March-April. 



2. N. racemosa Nutt. Resembling the last in habit, but less 

 prickly; leaves often bipinnatifid; petioles not strongly winged, 

 not clasping; flowers distinctly racemose, less than 10 mm. broad, 

 usually pale; scales narrow, the upper half commonly free. 



Frequent among shrubs on shady slopes in the vicinity of San 

 Diego, where it was first collected by Nuttall. It has also been 

 collected on Catalina and San Clemente Islands. March-May. 



3. N. insignis Dougl. Stems much branched, spreading, 1-3 

 dm. long, nearly glabrous or somewhat pubescent with more or less 

 retrorse hairs; leaves mostly bipinnatifid, pubescent with spreading 

 hairs, 2-5 cm. long, lobes elliptic-ovate; peduncles mostly 25-45 

 mm. long; calyx-lobes ovate-lanceolate, acute; corolla 15-25 mm. 

 broad, rotate-campanulate, the tube scarcely half the length of the 

 lobes, usually deep blue, slightly hairy toward the base; scales rather 

 broad, ciliate; seeds usually 12, corrugate-roughened. 



Frequent on sandy or dry plains and foothills throughout our 

 range. The rather persistent cotyledons are usually spatulate. 

 March-April. 



4. N. integrifolia (Parish) Abrams. Stems usually much 

 branched, rather weak and spreading, somewhat densely pubescent 

 throughout w^ith spreading hairs, the petioles nearly ciliate; leaves 

 2-3-toothed or pinnatifid, seldom entire; peduncles slender and 

 usually exceeding the leaves; calyx-lobes lanceolate, acute and 

 mucronulate; corolla usually less than 1 cm. broad, rotate-campanu- 

 late to nearly rotate, pale blue or nearly white, with darker veinlets, 

 hairy toward the base; scales linear, the upper half usually free, 

 hairy; seeds usually 8-12, corrugate-roughened, sometimes minutely 

 so, globose. {N. menziesii integrifolia Parish.) 



Rather common in the chaparral belt in all the hills and valleys, 

 especially away from the coast. April-May. 



2. EUCRYPTA Nutt. 



Erect paniculately branched viscid annuals, with 

 small racemose flowers. Calyx 5-parted, the sinuses 

 naked. Corolla small, tubular-campanulate, without 

 appendages. Capsule globose, 1-celled, with 2 dilated 

 placentae lining the pericarp, 2-valved, 8-seeded, 2 seeds 

 remaining in each valve between the pericarp and the 

 placentae after dehiscence. Seeds corrugated or smooth. 



^ 1. E. chrysanthemifolia (Benth.) Greene. Stems rather slender, 

 widely branching, 3-9 dm. high; leaves ample, 2-3-pinnatifid;
