80 LEAFLETS. 



longed apex : nutlets apparently 4, or sometimeB 3 only, a half- 

 line long, elongated-ovate above a truncate base, rather abruptly 

 and obtusely pointed, the ventral groove forked at base and 

 closed throughout, the whole surface greyish mottled with dark- 

 brown, smooth and polished. 



On Nine-Mile Creek, at 5,800 feet, Culbertson, 30 Aug., 1904; 

 Baker's n. 4537. 



Galium Culbektson'ii. Rigid herbaceous perennial, with, 

 nearly simple stems about a foot high from horizontal sublig- 

 neous rootstocks at least partly subterranean : angles of the stem 

 as well as margin and midvein of the leaves, minutely villous- 

 hispid, a more minute and partly appressed pubescence between 

 the angles of the stem : leaves in fours, of firm texture, less than 

 i inch long, oval, but ending in a very prominent cusp : flowers 

 few, minute, greenish : fruits (immature) apparently baccate, on 

 deflexed pedicels of i to i inch long, to the unaided eye appear- 

 ing glabrous, but under a lens seen to be sparsely and minutely 

 hispidulous-hairy. 



South fork the Kaweah River, 20 June, 1904, J. D. Culbert- 

 son. The near affinities of this Galium are not obvious to me. 



Chetsothamnus vulcan^icus. Shrub allied to C. Parryi of 

 Colorado, more slender, the leaves very narrowly linear and 

 very acute, indistinctly 3-nerved throughout, glabrous, or when 

 young obscurely glandular and viscid ; heads forming a narrow 

 thyrsiform panicle, the head little more than \ inch high, nar- 

 row, mostly 5-flowered, its bracts about 10, thin, lanceolate-sub- 

 ulate, slender pointed, the outermost more herbaceous, and 

 woolly on the margin at the base : corollas rather deeply cleft, 

 the teeth always erect : pappus copious, achenes silky-villous. 



On Volcano Greek, above Volcano Falls, at 8,000 feet, 9 Aug. 

 C. Parryi has much broader foliage, a more leafy thyrsus, and 

 broader involucres with flowers twice as numerous. 



Chrtsothamkus asper. Resembling the last, though 

 stouter, the wooliness of the stems more loose and white ; leaves 

 as narrow but firmer, rather strongly glandular-scabrous under 

 a lens, this indument extending to the outer bracts of the in- 

 volucres : heads subsessile, forming a more strictly thyrsoid in-
