ADDITIONS TO THE FLORA OF LOS ANGELES COUNTY, I
by Le Roy Abrams, Stanford University

1. Pinus murrayana. San Antonio Mountain.
2. Sitanion rigidum. Summit of Mt. San Antonio.
3. Bromus carinatus californicus. Fruitland, along irrigating ditches.
4. Lepturus cylindricus. Mesmer.
5. Melica imperfecta minor. Canyon near Chatsworth Park.
6. Phalaris lemmoni. Inglewood.
7. Agropyron parishii laeve. Ballona Creek, near Mesmer.
8. Alopecurus geniculatus. Not typical, perhaps a distinct form...has been collected near San Diego.
9. Quercus lobata. There are some excellent trees of this species at Chatsworth Park.
10. Quercus wislizeni. This species is frequent on the coast slope of the Sierra Madre Mountains. I have also obtained it in the San Antonio, San Bernardino, and Santa Ana Ranges. Only the scrubby form seems to occur with us, and it has been confused with Quercus dumosa Nutt.
11. Castanopsis sempervirens... This species occurs in the San Antonio Mts., above 8000 ft.
12. Eschscholtzia californica. Sierra Madre; Chatsworth Park. - Perennial.
13. Eschscholtzia peninsularis. The common species. - Annual.
14. Eschscholtzia hypecoides. Saddle Peak.
15. Lepidium lasiocarpum. Sand Dunes, Ballona Harbor. Related to L. oxycarpum T. and G.
16. Arabis virginica. Inglewood.
17. Heuchera elegans Abrams. Wilson's Peak; Mt. Lowe. Heuchera rubescens of local lists, not of Torr.
18. Heuchera rubescens. Mt. San Antonio .
19. Ribes cereum. Mt. San Antonio.
20. Ribes malvaceum viridifolium Abrams. San Gabriel Mts. above 3000 ft.; Santa Monica Mts.

My 25 years of scientific research that lead to discovery of LeRoy Abrams' Ballona field notes enlightens us with knowledge and power about the possibility for genuine restoration and genuine recovery of extirpated (locally extinct) native plants. LeRoy Abrams' five year project (1899 to 1903) also resulted in his first book: Flora of Los Angeles and Vicinity (Abrams, 1904). This book and his Ballona field notebooks (in Ballona Institute archives), in conjunction with his scientific articles such as that appended above allows restoration ecologists to practice genuine conservation. For example, we know the genuine plants to restore such as species #4 & #7 to Mesmer, #15 & #22 to Playa del Rey, and #6 & #16 to Inglewood. In essence, we can restore the Ballona Valley ecosystem with its prairie-wetlands, vernal pools, sand dunes and coastal salt-marsh to its wild native glory of 1903, approximately a century ago, when the above article was originally written and published in the Bulletin of the Southern California Academy of Sciences.
