Bhus lentil, (Kellogg). Stem stoutly branched, leafy, the younger 

 branches somewhat angled. 



Leaves ovate, or sub-acute, (one to one and one-half inches long) 

 alternate, petioles about one-eighth to one-fourth of an inch in length, 

 quite entire ; margins rounded, corneous, pinnate veins imbedded in 

 the thick coriaceous lamina. Leaves pale dull velvety glaucous, and 

 minutely short pubescent above; densely white hoary villous beneath. 



Flowers in terminal open compound panicles, peduncles and pedicels 

 one eighth to one-fourth of an inch long, hoary, short hirsute. Calyx 

 segments 5, ovate, sub-acute, both surfaces hirsute, thick carinated ; 

 margins thinner, translucent, very villous. Petals five, ovate, both 

 surfaces short hoary hirsute, hairs longer towards the inner base of the 

 short claw. Stamens five, glabrous, inserted into the conspicuous cre- 

 nated torus, or smooth fleshy disk. Style one, hirsute, stigma two- 

 parted, sub-capitate about equal. 



Fruit large (about 2 an inch in breadth), rhomboid, compressed, the 

 drupe somewhat fleshy, densely clothed with red acid hairs. 



This species closely resembles R. laurina of Santa Barbara and its 

 vicinity. Our specimens from that locality, however, have dentate 

 varnished leaves with very prominent veins, and of a different form ; 

 also crowded axillary and terminal panicles ; flowers in R. lentii 

 larger, 8 or 4 times the size. Calyx bright scarlet, quite ornamental; 

 petals of a lighter tinge, about twice the length of the calyx ; flowers 

 perfect. 



This species of Rhus would be considered by some authors as a 

 Malosma, or more properly Lithrcea of Miers, an originally Chilian 

 genus. 



Linosyris Dentatus, (Kellogg). — Stem two to three feet in height, 

 suffruticose, light and hoary. 



Leaves crowded and fasciculate, cuneate-spatulate, sessile, 3-nerved, 

 cut-serrate, mostly at the rounded sub-acute apex, remote or entire 

 towards the base ; teeth very sharp, with a horny mucro, pruinose 

 ciliate near the stem, scabrous above and below. 



Flowers at the extremity of the leaf branches, in compound clus- 

 tered sub-capitate corymbs, the corymbose subdivisions somewhat um- 

 belletiform, or three or four pedicels springing from a common point, 

 with lance-linear bractoid involucels surrounding the common base. 

 Heads twenty to twenty-five-flowered, obovoid. 



Scales of the involucre numerous, unequal, imbricated in five or six 

 series, outer short, oblong-lanceolate brownish tips, glandular on the 

 back ; margins thin scarious ; apex acute, dentate, carinate ; inner 

 scales linear membranaceous, longer than the disk. Receptacle alve- 

 olate toothed.
