pletely enwrapping the ovary, deciduous, its margin entire, in 

 pubescent forms tomentose-ciliate, in other forms nearly naked: 

 calyx dark purple, 4-6 lines long, cylindrical-tubular with re- 

 flexed segments: filaments subulate, scarcely exceeding the 

 erose-dentate involute white petals; anthers a line long, ovate, 

 acute, tipped with a blunt or even truncate mucro: ovary 

 prickly. 



Interior valleys of Humboldt County, California, near Gar- 

 berville, Miss Bush; also in Hoopa Valley, Mr. C. C. Marshall, 

 1887. 



Shrub with the aspect of R. Menziesii^ from which it is 

 readily distinguished by the solitary deciduous bract which, 

 until it falls aw^ay, enfolds the ovary. The proportions of tube 

 and limb of the calyx are no less distinctive, the former being 

 long, cylindrical and lo-striate. I am obliged to admit, as forms 

 of one species, the almost hoary shrub of the Garberville region 

 and the nearly glabrous one of the district farther north. This 

 kind of variability is somewhat common on this coast, among 

 the species of Ribes. My R. velutinum (Bull. Cal. Acad. i. 83), 

 which, as I know it in northern California, is covered all over, 

 even to the fruit, with an almost velvety pubescence, I now 

 have from Mr. Cusick, of northern Oregon, in a perfectly glab- 

 rous state. 



As might be inferred, the above description includes two species, the glab- 

 rate plant from Hoopa Valley later being referred to R. cruentum. R. amictum 

 is common in the northern Sierras, in fact more so than in the type region. It 

 is also reported from the southern Sierras, but specimens from that region are 

 probably referable to some other species. 



32. Ribes Wilsoiiianuin Greene, Erythea, 3: 70. 1895. 



Rigid and low shrub, with smooth branchlets and i to 3 

 spines at each node: growing parts and leaves more or less vil- 

 lous with a short pubescence: leaves small, rounded, 5-lobed, the 

 lobes and teeth acute: peduncles rather slender, mostly 3-flow- 

 ered: bracts persistent, broadly ovate, acuminate-cuspidate, vil- 

 lous: ovary short-prickly, scarcely villous: calyx dark red, the
