IMMIGRANT PLANTS IN LOS ANGELES COUNTY, CALIFORNIA. 59 
since discovered, near the Cienega, two clumps of this 
fragrant plant, growing to the height of some four feet. In 
this station it is likely to remain unmolested. 
Trifolium repens, Rivin. In the city lawns this is quite 
common, and where not eradicated promptly, soon covers the 
whole ground, the grasses receding before it; but outside of 
these places this clover at present scarcely exists. 
Vicia sativa, L. As might be expected, this relic of early 
Spanish settlers is annually met with in the environs of Los 
Angeles, but may be considered somewhat rare. 
Mesembryanthemum equilaterale, Haw. Plentiful on sand 
dunes along the sea shore. M. erystalli , L., grows with 
the preceding, but also affects low and subsaline soils back 
from the sea, even penetrating nearly to the city boundary 
on the coast side. M. nodiflorum, Haw. Common along 
the Eastern coast of Catalina Island. 
Apium graveolens, L. Of all the Umbelliferx this is the 
most firmly naturalized and must have been introduced at an 
early period, as it is not only widely diffused, but covers in 
dense masses acres of ground to the westward of the city. 
Pastinaca sativa, L. A few years ago this was somewhat 
searce in the Cienega. Now it is fairly common, and will 
probably increase. 
Feeniculum vulgare, Ger. Plentiful in the city where it 
has acquired a perennial habit of growth, its stout and 
numerous stems forming quite dense masses. 
Daucus Carota, L. An occasional escape. 
Coriandrum sativum, L. A few plants have been seen on 
the streets of Los Angeles. ee 
Peucedanum graveolens, B. & H. A casual? 
Galium Aparine, L. Not infrequent along the seaboard. 
G. spurium, L. Rarer than the last and ranging more 
~ Inland. 
Dipsacus fullonum, L. Established near the woolen 
mills, where the heads are used in cloth manufacture. 
Erigeron Canadensis, L., grows abundantly and luxuri- 
antly on waste grounds everywhere near Los Angeles.
