INTRODUCTORY. é

“THE first list of the Flora of Los Angeles County was issued by the author in October, 1892, and comprised almost all the then known species on the mainland of the County. Since that time the district

has been more thoroughly explored, and numerous additions have been

made to the list, not a few of which are of species entirely new to science.

In view of these additions the Botanical Section of the Southern California

Academy of Sciences has deemed it advisable to issue a second list, to

include the plants of both the mainland and the Islands of San Clemente

and Catalina, which are embraced in the County area.

In the compilation of this list“ désire to express my sincere thanks for the valuable aid rendered by Miss A. J. Merritt, Normal School, Los Angeles; Dr. Hasse, of Santa Monica, and Mr. S. B. Parish, of San Ber- nardino, who have not only placed the accumulated experience of years of investigation at my disposal, but have also revised the manuscript. To the latter gentleman, whose knowledge of the Flora of Southern California is not surpassed by tkat of any living authority, I am also indebted for the final revision of the proofs.

From the “Flora of Pasadena,’’ issued by Mr. A. J. McClatchie, I have taken additional records of locality, and the records of species therein quoted which are not familiar to my colleagues or wyself are duly acknowledged. Under these conditions this Catalogue may be considered at least fairly accurate.

Some of the species have one or two asterisks prefixed. One * indicates those recorded of which we have seen no authentic specimens, some of which we feel assured have been wrongly identified. The original authority is appended. Two ** indicate those recorded in the Botany of California, Brewer & Watson’s second edition, which have not, so far as we are aware, been collected in recent years.

The names printed in italics indicate those species believed to be non- natives of this county.

Local lists without a collection to indicate exactly the plants referred to are of doubtful scientific value. While we are without a museum or other public institution in which to deposit the collections on which this list is founded, the species indicated may be found in the herbaria of the collaborators.

In the present disturbed state of botanical nomenclature neither the method of arrangement nor the specific names chosen may be considered either modern enough, or ancient enough, to suit the pedagogues. For this

the author is alone to blame, his aim in this work having been to produce a useful field guide for the botanists of this coast, and not a critical treatise on species or varieties.

The localities given it is hoped are numerous enough to denote ina general way the rarity or frequency of the plant, its distribution and alti- tudinal range.

The time of flowering it has been thought advisable to omit, as the period of the winter rains, and the altitude of the district have as marked a determining influence as the aerial temperature.

The County of Los Angeles covers 4,000 square miles of land with a seacoast line of about Ioo miles in length. In the land area are included the coast and San Gabriel mountains (the latter reaching to an altitude of 6,000 feet) and the Southern section of the Mojave Desert. The flora is in consequence a varied and extensive one, and comprises a larger number of species than are found in many of the Eastern States.

The number of species and varieties listed in the first Catalogue was 854. In the present list the numbers are 961, divided as follows:

Phzenogamia.. svavessnse9 34 Filices........... . 20 Equisetacee..... 4 Sellaginellaceze. I Marsileacez... I SaAlVIM TAGE ss i ts sciasconevaaiatanscdasdecmme I

One new species, a hybrid of our common Audibertias, is here pub- lished for the first time.

The Botanical Section of the Academy of Sciences has in contemplation the completion of the Floral list by the publication of a second part at some time in the near future, when the resources of the county have been more fully explored.

AUDIBERTIA STACHYOIDES X POLYSTACHYA.

Shrubby resembling in appearance A. stachyoides; stems hoary; leaves hoary tomentose less rugose than in A. stachyoides and slightly folded; bracts akin to those of 4. stachyoides, flower g lines long, upper lip 2% lines long, slightly cleft, lower lip in shape resembling that of 4. polystachya, straight or slightly folded; no hairs beyond the throat; Stamens 4% lines long as long or longer than the lower lip and divergent. Flowering, April, May and June. :

Botanists have previously considered these hybrids as but forms of a a variable species, but they seem to be genuine hybrids. Two main types of this hybrid are to be found, one closely allied to 4. stachyoides and the other more nearly allied to A. polystachya. Only occasionally are the ’ whorls of the inflorescence arranged as in 4. Polystachya. The foliage is always more or less tomentose, and the shape of the leaf is exactly interme- diate between the straight form of A. stachyoides and the folded form of A. Polystachya. The flower is intermediate in size between that of 4. stachy- oides and A. polystachya with the upper lip nearly of the size and shape of that of the former and the lower lip «f that of the latter. The stamens in 1. stachyoides stand upright against the upper lip; in 4. polystachya they diverge against the lower lip; in the hybrid they occupy an intermediate position between those points.

This hybrid is quitecommon in the foothills and at Lincoln Park where it was first discovered by Miss Alice J. Merritt.

For illustration see page 36.
