believed an exclusive resident of the 

 suburban parts of San Diego, occurring 

 on the hills facing the sea near Del 

 Mar. A second small grove has been 

 discovered on Santa Rosa island. 

 Where most exposed it forms a low, 

 scraggly shrub, 2 or 3 feet high only at 

 times, but spereading over a wide area; 

 at its best estate it forms a small, 

 graceful tree 20 to 30 feet high, a foot 

 or more in diameter. The very stout 

 leaves are 8 by 11 inches long, 5 in a 

 sheath. The edible seeds, 8-11 lines 

 long, with a very hard shell, produced 

 in an ovate cone, 4-5 inches long and 

 nearly as great diameter. 



WASHINGTONIA FILIFERA Wendl. 



The California fan palm, bearing 

 great clusters of small black berries, 

 the clusters weighing 10 to 20 pounds 

 each, furnished the desert Indians 

 with a most important article of food, 

 equal to that of the pinon nuts to the 

 mountain tribes, ranking next in val- 

 ue to the mesquite bean. The berries 

 have a thin, very sweet, and pleasant 

 flavored pulp, which any palate might 

 appreciate. 



CONVOLVULUS LUTEOLUS A. Gray. 



Stems three-fourths to 1% ft. long, as- 

 cending, or more elongated and twining: 

 bracts about their own length distant 

 from the calyx, narrowly oblong to line- 

 ar-lanceolate, 2-4 lines long, much small- 

 er than the very obtuse unequal sepals: 

 corolla l-iy 2 in. long, campanulate-funnel- 

 form. pale yellow: stigmas linear. 

 CONVOLVULUS LONGIPES S. Watson. 



Erect, much branched feebly twining 

 perennial, glabrous throughout; small- 

 leaved. Desert regions, Cal., Nevada. 



Genus MIMETANTHE Greene. 

 Calyx campanulate, 5-cleft, the tube 

 somewhat 5-sulcate, neither angled nor 

 ribbed: lobes unequal, the uppermost 

 largest. Corolla tubular-funnelform, 

 Stamens 4, didynamous. Style gla- 

 brous; stigma bilamellar. Capsule ob- 

 long-ovate, rather acuminate, equal- 

 ling the calyx, not gibbous at base, 

 minutely glandular, chartaceous, dehis- 

 cent by the whole of the upper suture, 

 by the lower only to the base of the 

 apical acumination, both valves in de- 

 'hiscence strongly reflexed in so far as 

 separated; placentae born on the mid- 

 dle of the valves, many seeded. Seed 

 minute, oblong-ovate, yellowish, under 

 the microscope favose-reticulate and 

 glandular." Greene Cal ac b 1:181.

MIMETANTHA PILQSA Greene. 



A villous glandular annual, with a 

 sickening solanaceous odor. Baja Cal. 

 to Washington. 



NICOTIANA GLAUCA L. 



Leaves long-petioled, subcordate: cor 

 y: shrub 8-15 ft, high. "The large glau- 

 cous, thickish leaves are used as healing 

 and anodyne poultices." Ha vard. Nat- 

 uralized from So. Am. 

 QUERCUS AGRIFOLIA Nee. 



The California live oak is justly one 

 of the trees described as picturesque, 

 the stout, low trunk 8, to even 20 feet, 

 In circumference, with a spread of 

 branches of 120 feet. Mendocino coun- 

 y appears to be its northern limit, while 

 near La Grulla, south of Ensenada, 

 Lower California, is the most south- 

 ern recorded station, where its 

 branches sweep the ground. The shin- 

 ing, elongated, tapering, acute-pointed 

 acorn, 1-1% inches long, and ^4 to 1-3 

 inch in diameter, characterizes the 

 species and are among the treasured 

 trophies of the average tourist, who of- 

 ten says he "can taste them still" but 

 generally prefers not to do so the sec- 

 ond time. 

 JUGLANS CALIFORNICA S. Watson. 



The California black walnut is usu- 

 a^ly a small tree, growing SO to 

 75 feet high, 2 to 4 feet in diameter, 

 bearing a roundish nut, the kernel 

 sweet and delicate in flavor. Occurs 

 from along the Sacramento river to 

 San Diego county, California; occa- 

 sionally cultivated, but more as a shade 

 or street tree, than for its excellent, 

 nuts. 

 IRTS MACROS1PHON Torr. 



Stems very slender, flattened, surpassed 

 by the dark green grass-like leaves: fls 

 rich p-blue, on short pedicels. Mts. San 

 Diego Or 1056. 

 ERYSIMUM INSULARE Greene. 



"Shrubby, diffuse, a foot high. form, 

 ing a dense tuft of from 2-6 ft. broad, 

 cinereous with a minute appressed pu- 

 bescence, or glabrate; leaves narrowly 

 linear, canaliculate, entire, rather rig- 

 id, recurved at apex, crowded upon the 

 numerous woody branches; racemes 

 short and dense, on short pedun- 

 cles, or almost sessile; corolla yellow, 

 % inch broad; siliques quadrangular, 

 2 inches long, iy 2 -2 lines thick, beaked 

 with a stout style. Sandy slopes above 

 Cuyler's Harbor, Island of San Mi- 

 guel." Greene, Torr cl b 13:218 (N 

 1886).
