broadly ovate to orbicular, acuminate, three-angled, clasping, 

 reflexed. Calyx 12mm. long, the linear, acute segments more 

 than twice as long as the tube, 2mm. wide, apparently white, 

 veined with parallel veins that branch near the apex, puberulent 

 or glabrous. Petals involute, obovate when spread out, irregu- 

 larly denticulate at apex, 3mm. long, veins palmate. Filaments 

 almost twice as long as the petals, dilated at base; anthers ob- 

 long-ovate, cordate at base, tipped with a recurved mucro. 

 Style divided two-thirds of its length, slightly exserted. Young 

 fruit puberulent, clothed with a few long spines (about ten) each 

 about 5mm. long. 



Related to Ribes californicum Hook. & Arn. from which it 

 differs in the sparsely spinous fruit, the glabrous leaves, the lax 

 inflorescence, and the shape of the floral organs. 



Collected by the author on the road between Jolon and 

 King City, in Monterey County, California, near Mansfield's 

 Ranch, ten miles from King City, May, 1897. 



This species is really more closely related to R. occidentale than to R. Cal- 

 Harnictim, but is distinct from both. 



y 25. Ribes Victoris Greene, Pittonia, 1: 224. 1888. 



A somewhat slender spinescent shrub, 5 feet high, younger 

 branches very prickly, young growing parts puberulent and 

 somewhat viscid: leaves an inch broad, 3 to 5-lobed, on slender 

 petioles subtended by not very stout triple spines: pedicels with 

 I or 2 persistent entire bracts and as many large nodding green- 

 ish white flowers: calyx-lobes linear-oblong, recurved: petals 

 acutish at apex, and erose-toothed: filaments not exceeding the 

 petals; anthers ovate-oblong, broad but not sagittate at base, ob- 

 tusish at apex but not mucronate: ovary glandular-hirsute: fruit 

 unknown. 



Collected near the base of Mt. Tamalpais, in Marin County, 

 California, by Mr. Victor K. Chesnut, a pupil of mine to whom 

 I gladly dedicate the species; also by Dr. C. C. Parry, in Ruth- 

 erford Canon, Napa Valley, in May, 1887: nearly related to R.
