long, finely pubescent, S-seeded, equalling or a little exceeding the 

 enlarged calyx. — On rocky hillsides near Santa Cruz, Sonora, Thur- 

 ber (ii. 943), 1851 ; Santa Cataliua Mountains, Arizona, Leminou 

 (n. 130), 1881, and by Parish and Pringle, 1884; Northwestern So- 

 nora, Pringle, 1884; Cedros Islands, Lower California, by Dr. T. H. 

 Streets in 187G, and at Tia Juana, by Orcutt. Much resembling a 

 species collected by Berlandier in Northeastern Mexico (n. 1550, 3050, 

 and 3108; A. Berlandierl, Gray, in herb.), which, however, has more 

 acuminate calyx-lobes, larger flowers, and more acuminate carpels witii 

 coarser stellate pubescence, the peduncles often several-flowered, and 

 leaves usually more oblong and more acuminate. 



Sageretia Wrigiitii. a shrub 2 to 5 feet high, with slender 

 spreading pubescent branches and brauchlets : leaves thin, bright green 

 and shining on both sides, very sparsely villous on the midvein beneath, 

 oblong or sometimes elliptical to lanceolate, acute or obtuse or some- 

 times emarginate, cuneate to subcordate at base, sparingly acutely ser- 

 rulate, 4 to 8 lines or sometimes an inch long, with a short slender 

 petiole : panicle very short (an inch long or less), often reduced to a 

 short spike or even to a few flowers in the uppermost axils ; sepals 

 ovate, acute: fruit unknown. — Collected by Wright (n. 925) in 1851 

 at Santa Cruz, Sonora (referred to S. Michauxii in PI. "Wright. 2. 28, 

 and in Ilemsley, Bot. Biol. Cent.-Amer. 1. 200), by Dr. V. Havard 

 at the Falls of Capote Creek, W. Texas, in October, 1883, and by 

 C. G. Pringle on the foothills of the Santa Rita Mountains, Arizona, 

 in July, 1884. S. Michauxii, of the Atlantic States, has smoother 

 branches, more ovate and usually acuminate crenately toothed leaves, 

 and more numerous flowers, with the calyx-lobes more lanceolate. 



Rhus (Styphonia) ovata. A shrub, 5 to 10 feet high, glabrous 

 excepting the finely pubescent branches and the bracts of the inflores- 

 cence : leaves coriaceous and shining, ovate, acute or acuminate, entire 

 or rarely sparingly toothed, 2 or 3 inches long, on a stout usually red- 

 dish petiole 4 to 8 lines long : flowers in dense closely panicled spikes 

 a half-inch long or less, the rounded bracts and sepals purplish ; petals 

 light yellow : fruit compressed-ovate, 2 or 3 lines long, viscid-pubes- 

 cent. — On hills and mountains, away from the coast, from San Diego 

 to Los Angeles County, the Cantillas Mountains in Lower California, 

 and in Southern Arizona ; also on Santa Catalina Island (W. H. 

 Lyon). It has been confounded with the coast species R. integrifolia 

 (and figured for it by Torrey in Pac. R. Uep. 7. 9, t. 2, excepting the 

 single leaf), which has smaller obtuse and more frequently serrate 

 leaves with shorter petioles, more pubescent, and with twice longer
