CATALOGUE OF SPECIES. 135 



Plant 10 cm. or less high, with a few divaricate branches exceeding the main axis, 

 scantily cobwebby up to the inflorescence, becoming smooth in age; branches 

 brown, slender, terete, with usually but one or two long internodes; cotyledons 

 oblong, sessile, connate into a scarious cup; leaves scattered, involute-filiform, 

 obtuse at the apex, 1 to 2.5 cm. long; antbodia G to 8 mm. high, in glomerules of 2 

 to 5, terminating the branches, each subtended by a leaf, rayless; involucre com- 

 posed of 4 herbaceous, linear-oblong, obtuse, slightly concave, externally minutely 

 glandular bracts; flowers 4, hermaphrodite, one-half longer than the involucre; 

 pappus a deciduous coherent ring of 12 to 17 spatnlate, erose-iimbriate, hyaline paleai 

 slightly thickened in the stalk and middle of the blade; corolla 3 to 4 mm. long, 

 yellow, minutely glandular, proper tube about .5 mm. long, throat long, cylindrical, 

 lobes 5, triangular-ovate, the one outermost in the anthodinm longer than the others ; 

 stamens and stigmas in the fresh plant included; filaments nearly as broad as the 

 anthers, abruptly contracted to a narrow neck at the apex; anthers merely sagittate 

 at the base, the hyaline apical appendages obtuse; stigmas clothed on the back 

 and sides with short, obtuse, gland-like hairs; achenia about 18-striate, dotted 

 with minute sessile glands, black or at full maturity perhaps gray. 



The plant grew abundantly in the well-drained granitic soil about Whitney 

 Meadows (No. 1685), and in similar situations at Big Cottonwood Meadows (No. 

 2142). These stations, which appear to he typical ones, are in the belt of 

 1'inuH mttrrayana and P. balfouriana. A few specimens were seen in the belt 

 of Vlnux jeffreyi, along the Hockett Trail, near Soda- Springs (No. 1607), but this 

 station is below the customary range of the species. The type locality of the plant is 

 probably a little farther south in the Sierra Nevada, but the station was not 

 recorded. 



Syntrichopappus fremontii Gray, Pac. R. Rep. iv. 106 (1857). Type locality, 

 "somewhere between the Pocky Mountains and the Sierra Nevada." 

 On the Darwin Mesa (No. 793), and in Sarcobatus Flat, Nevada (No. 2141). 



Eriophyllum ambiguum Gray, Proc. Araer. Acad. vi. 547 (1865), under Lasthenia; 

 Gray, Proc. Amer. Acad. xix. 26 (1883). Type locality, "near Fort Tejon," California. 



In our plant, the conical receptacle bears near its apex short, weak bristles that 

 persist after the fully matured achenia have fallen. In removing the achenia, if 

 they are not quite mature, the bristles are easily broken off and the receptacle 

 appears smooth. The species was found in the Funeral Mountains, near Mesquite 

 Spring (No. 325), and in Johnson (No. 533), Surprise, ami Willow Creek canons 

 (No. 834), Panamint Mountains. 



Eriophyllum csespitosum Tamil. Bot. Reg. xiv. t. 1167 (1828) — Douglas MS. 

 Type locality, "in North-west America, in abundance, from the sea to the valley of 

 the Rocky Mountains." 



tiuct, slightly concave bracts; flowers as many as the bracts, greenish yellow, 

 hermaphrodite; corolla 5-tootbed, the tooth outermost in tin' anthodinm slightly 

 longer than the others; stamens inserted at the base of the corolla; anthers sagit- 

 tate, not caudate; stigma lobes linear, without appendage, obtuse, clothed with 

 short, blunt hairs ; achenia terete, striate, clavate-obovate ; pappus of several obtuse, 

 membranaceous, erose-iimbriate palete coherently deciduous. 



The genus is allied to Chamactis, but differs in its few-flowered glomerulate heads, 

 few-bracted involucre, coherent deciduous pappus, sessile antbodia, and habit, and 

 from all the species of that genus save C. cusickii in its entire leaves. The generic 

 name is derived from bpog, mountain, and Ckcenactis, the name of the most nearly 

 related genus, reduced to Ave syllables ; for the plant grows at high altitudes in the 

 Sierra Nevada of California.
