122 LEAFLETS. 
8 inches from the base of petiole to apex of terminal leaflet, the 
leaflet 24 to 4 inches long, often 3 in width, of oval or ovate 
outline, coarsely but not deeply crenate-lobed but the lobes all 
abruptly acutish, the texture thin even in autumnal maturity, of 
a deep rich green above, paler beneath and with slight pubes- 
cence along the veins: inflorescence a simple raceme in the axil 
of every leaf, never panicled, the fruits seldom more than :2 or 
3 to each raceme, but pedicels slender and drooping: striae of 
fruit indistinct, obscured by a strong very irregular wrinkling 
of the whole epicarp. 
Little Chico Creek, Butte Co. Calif., Mrs. R. M. Austin, 1896, 
both early summer and late autumnal specimens, reported to 
sustain itself to the height of 20 feet on oak trees. 
T. vaccaruM. Stems slender, upright, the branchlets not 
striate, obviously knotted by small infrapetiolar protuberances, 
densely puberulent: leaves of the smallest, the leaflets from į 
to 1 inch long, rather deeply and angularly 5-lobed, dark 
green and glabrous above, paler and pubescent beneath especial- 
ly along the veins: inflorescence a simple ascending and rather 
long raceme in the axil of each leaf: staminate flowers very 
small, with short subquadrate anthers on still shorter filaments: 
fruit unknown. 
Cow Creek Mountains, Shasta Co. Calif., Baker & Nutting, 
1894. This shrub can be compared with no other species of the 
genus. It is unequivocally of the diversi/obum group, but, with 
its long slender upright racemes of small flowers, and its sharp- 
ly angled foliage, it looks more like a currant bush. 
T. DIVARICATUM. Branches only sparsely leafy, elongated 
and curved, the shrub, perhaps, reclining or trailing but not root- 
ing, the bark greenish-gray, minutely hirtellous: leaves elon- 
gated and long-stalked, the whole 6 to 10 inches long; leaflets 
subcoriaceous, entire, deep-green and glabrous above, beneath 
with villous midvein but otherwise nearly glabrous, the termi- 
nal ovate, acuminate, 2 to 4 inches long, the pair remote from 
it, smaller, very inequilateral: panicles small, sessile, neither 
erect nor ascending but spreading divaricately: fruits very 
small, depressed-globose: epicarp polished, not wrinkled, only 
faintly striate, ar 7
