to Sierra county. Hooker probably co.ifused several species, but his type is 

 the plant collected by Douglas, 



40. Kibes lasianthniiii Greene, Pittonia, 3: 22. 1896. 

 Stout, low, widely spreading and intricately branched, the 



height seldom exceeding 2 feet: branches glabrous; infrastipular 

 spines commonly 3, rather slender, straight: rounded leaves Yi 

 to ^ inch broad, short petioled, pubescent, cleft to the middle 

 into 3 terminal lobes, with 2 to 4 more shallow and less distinct 

 lateral or basal ones, all these 3-lobed at apex, the siimses 

 closed: flowers 3 or 4, in very short-peduncled racemes, yellow; 

 calyx about 5 lines long, the hirsute tube much dilated above 

 the ovary, thence tapering gradually to the spreading spatulate 

 lobes; petals also spatulate, shorter than the calyx-lobes; young 

 ovaries hairy: fruit unknown. 



An almost alpine species, flowering in the latter part of 

 July, near the receding snow-drifts in the mountains of Califor- 

 nia above Donner Lake, toward Castle Peak. Somewhat re- 

 lated to R. leptanthimi of the Rocky Mountains, though also 

 akin to R. quercetorum of the Californian Coast range south- 

 ward. 



From specimens gathered by me last year at the type locality, several char- 

 acters may be added to the description of the flower. The calyx is hirsute 

 outside throughout about 8mm. long, the tube 5mm., the oblong lobes nearly 

 2mm. wide: petals and stamens inserted at the junction point of tube and lobes, 

 the petals oblong-spatulate, white with pinkish or yellowish base 2mm. long, 

 equalling the stamens, which are included instead of exserted, as stated in the 

 key, the filaments broadly subulate, anthers nearly quadrate, about imm. wide: 

 style not extending beyond the petals and stamens, the stout stigma two lobed. 



41. Kibes Congdoni sp. nov. 



A straggling shrub, the secondary branches apparently at 

 right angles to the main ones: bark grayish, somewhat flaky on 

 the old branches, the more recent growths usually prickly and 

 pubescent: infrastipular spines usually single, pale brown or 

 yellowish, obout 5mm. long, slender from a slightly enlarged 

 base, straight, sharp and needle-like: leaves ovate-orbicular in
