ARCTOSTAPHYLOS. 35 



My first knowledge of this species was derived from a flowering spec- 

 imen in the herbarium of D. Cleveland, Esq., of vSan Diego, which 

 had been collected several years previous, in Jamul Walley, by Mr. O. 

 N. Sanford, by whom I was kindly supplied with additional specimens. 

 Not succeeding in again finding it at the original locality, it remained 

 imperfectly known till re-discovered in 1883, on a trip into Lower Cali- 

 fornia, near Todos-Santos Bay, where I succeeded in securing some 

 belated fruit of the previous season and leaf branches. Subsequently, 

 in April, 1883, my agreeable associate, Mr. C. R. Orcutt, discovered 

 this species growing abundantly in a wooded ravine near the Mission 

 of San Diego, thus making it available for continuous observation. 

 Unfortunately, owing to the dry season of 1883, the bushes failed to 

 produce flowers or show any indications of growth that season, and, 

 accordingly, all the material for clearing up this species was derived 

 from these ditferent sources, on which the following description is 

 based, viz. : 



8. A. arguia, Zucc, var. diversifolia. — Character extended, from 

 living specimens found near San Diego, 1882-3. — -Shrub six to fifteen 

 feet high; stems one to three inches in diameter, with light gray bark 

 slightly furrowed, on the upper branches shreddy, and on the young, 

 growing shoots tomentose ; leaves varying greatly in size and form, ac- 

 cording to position or season of growth; in young, vigorous off-shoots 

 or suckers, broadly lanceolate, three and one-half inches long by one 

 and one-half inches broad, smooth on both sides, reticulate, scarcely at 

 all revolute ; on the upper and flowering branches, narrowly lanceolate, 

 strongly revolute, and tomentose beneath, in all more or less irregu- 

 larly serrate, with mucronate cartilaginous teeth and short petioles. 

 Inflorescence racemose, from the axils of the upper terminal leaves, 

 secund and horizontal, rachis, bracts, pedicels, and calyx long tomen- 

 tose; bracts about half as long as the pedicels, corolla three lines 

 long, stamens ten (occasionally eight j, filaments bearded below, anther 

 appendages about as long as the anthers ; style shortly exserted ; ovary 

 hairy hispid above. Fruit small, two lines broad, warty, with a solid 

 five-celled putamen, cells more or less abortive. Needs comparison 

 with the Mexican type, which probably includes several published 

 species. 



Two more Pacific coast species remain to be noticed, which, on ac- 

 count of their peculiar characters, will require an additional section.
