80 LEAFLETS. 
longed apex ` nutlets apparently 4, or sometimes 2 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. 
Gatium CuLBertsonut. 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 
tinch long, oval, but ending in a very prominent cusp : flowers 
few, minute, greenish: fruits (immature) apparently baccate, on 
deflexed pedicels of ł to + 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. 
CHRYSOTHAMNUS VULCANICUS. Shrub allied to C.Parry/ 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 4 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 Creek, 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. 
CHRYSOTHAMNUS ASPER, Resembling the last, though 
stouter, the woolliness 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-
