Jepson 13.513; upper Jlarsh Creek, Mt. Diablo, Jcpson 9996; near Stanford, C. F. Baker 279; 

 Mt. Hamilton, Pnullcton 872. 



Var. hyBtriciUiim Jepson var. n. Stems prickly as in the species; leaves glandular beneath 

 as in the variety It'ptosmum, or the sessile glands obscure; ovary quite concealed by the dense 

 covering of spines, the spines gland-tipped. — (Caules aculeosi ; folia subtus glandula, vel glan- 

 dulis sessiiibus obscuris; ovarium spinis glanduloso inucronatis dense tectum.) — Mt. Diablo, at 

 summit, amongst Quercus chrysolepis {Mary Bowerman 314, type). 



Var. senile Jepson. Stems prickly; nodal spines on the season's growth often yellow; leaves 

 a little glaiidiilar; ovary densely white-hairy, the spines red, relatively few; berry a little villous, 

 armed with much-scattered very slender gland-tipped spines 1^ to 1% lines long. — East slope 

 of the Santa Cruz Mts. in Santa Clara Co.: Lake Kanch road, Pendleton 1328; Los Gates Canon, 

 A. H. Wolh>i-Do(l 216, 435. 



Var. retineatum Jepson var. n. Stems prickly; nodal spines yellow; leaves pilose-puberu- 

 lent and with a few stalked glands, especially beneath, tending to persist over the winter; pe- 

 duncles IH to 2 inches long; calyx-tube 2^^ lines long; berry black. — (Spinae nodorum flavae; 

 folia piloso-puberulentia, glandulis paucis, hiemem pcrsistere inclinata; pedunculi unc. 1^/4-2 

 longi; calycis tubus lin. 2^2 longus; bacca nigra.) — Santa Cruz Mts. on Gilroy grade to Watson- 

 ville (Jepson 13,510, type). 



Var. hystrix Jepson. Stems prickly; leaves thickish, thinly or weakly puberulent, sprinkled 

 beneath with sessile glands; peduncles 1 to 1^/4 inches long; berry large, purple, 6 to 7 lines in 

 diameter, spiny. — Monterey Count}' coast from Pt. Lobos to Point Gorda: Pt. Lobos, Pendleton 

 518; Limekiln Creek, Jepson 1681. First collected by Douglas, doubtless at Pt. Lobos near 

 Carmel Mission. 



Var. hesperium Jepson comb. n. Stems not prickly; leaves minutely puberulent, not glandu- 

 lar; calyx reddish-purple; ovary and berry glabrous or sometimes puberulent, densely covered 

 with slender spines, all the spines non-glandular, or a few shorter ones gland-tipped. — Canons, 

 800 to 3500 feet : Santa Inez Mts. ; Santa Monica Mts. ; San Gabriel Mts. 



Tax. note. — No other species of our Ribes have a berry so densely spiny as the var. hesperium 

 of R. menziesii. This particular character, as well as its flower and glabrous ovary and berry, 

 seems to indicate points of relationship with R. roezlii var. cruentum Rehd. 



Locs. — Santa Barbara; Santa Monica Canon, Barber 6; Sepulveda Canon, Santa Monica 

 Mts., Ahrams 3119; San Antonio Canon, Claremont, C. F. Baher 4063 ; Palmer Canon, Claremont,

Var. thacherianuin Jepson var. n. Stems not prickly; nodal spines few or none; leaf -blades 

 markedly puberulent beneath; petioles pilose; flowers 6 lines long; petals % as long as sepals. — 

 (Caules non aculeati; spinae nodorum paiicae vel absentes; folia subiter manifeste puberulenta; 

 petioli pilosi; flores lin. 6 longi.) — Santa Cruz Isl., Olive Tliacher. 



Var. faustum Jepson var. n. Stems not prickly; leaves subglabrous, thickly sprinkled be- 

 neath with stalked and especially sessile glands; anthers white or sometimes lavender; berry 

 rather thickly covered with equal short gland-tipped spines ^/^ line long. — (Caules non aculeati; 

 folia subglabra, subiter glandulis stipitatis vel praecipue sessiiibus sparsa; antherae aliquando 

 pallido-purpureae, bacca spinulis brevibus crebrae.) — Canons, Berkeley and Oakland hills:
