Rihes indecorum is nearest to Ribes malvaceum but differs 

 most noticeably in the much smaller and sessile flowers. 

 The floral organs, too, are not the same. 



4. Ribes ascendens, sp. nov. 



Plate XXIII, Figs. 4a and ^b. 



Erect shrub unarmed, with gray-brown bark on older stems, younger stems 

 paler and shreddy. Leaves three- to five-lobed, orbicular, reniform, 3-6 cm. 

 wide, 2-5 cm. long, crenate-dentate, almost glabrous on the upper surface, 

 the lower clothed with fine, spreading pubescence; petioles equalling or 

 shorter than the blades, glandular; stipular dilation narrow, fringed with 

 long, gland-tipped hairs. Peduncles generally surpassing the leaves, at first 

 erect, later nodding, glandular-pubescent; flowers crowded at the summit of 

 the peduncle, which is naked for more than half its length; bracts oblanceo- 

 late, rounded at apex, 7 mm. long, 2 mm. wide, with gland-tipped hairs on 

 the surface and margin; pedicels half as long as the bracts, lengthening with 

 age, and recurving upwards, so that the berries are erect. Flowers subtended 

 by two membranous bracteoles which are soon deciduous. Calyx open- 

 campanulate, rose-color, the tube about half as long as the divisions; these 

 ovate, obtuse, 3.5 mm. long, 2.5 mm. wide, slightly pubescent. Petals white, 

 orbicular, narrowed to a short, broad claw, 2 mm. wide. Stamens not equal- 

 ling the petals, filaments linear, anthers oblong. Ovary clothed with gland- 

 tipped hairs. Berry veiny, sparingly glandular, becoming 7 mm. or more in 

 diameter. 



This species is near R. nevadense Kellogg, but the racemes 

 are ascending when in flower. The floral organs also differ 

 in shape. 



The type was collected by the author at Millwood, 

 (Sequoia Mills) Fresno County, California, in flower, May 

 4, 1895; in fruit, July 18, 1893. There are specimens from 

 General Grant Grove in the same vicinity, and from Coburn's 

 Mills in Fresno County, collected by T. S. Brandegee; the 

 former, July, 1892, the latter. May 29 (year not given). 



\a. Ribes ascendens jasjberce, var. nov. (Plate XXIV, 

 fig. 5). This is similar to the species in general appear- 

 ance, but the sepals and petals are more orbicular, the 

 filaments are shorter, and the anthers broader and more 

 orbicular. It is named in honor of Mrs. William Jasper, 

 who sent the specimen from San Emidio Canon, Kern 

 County, California, May, 1895.
