166 PITTONIA. 
Kern River, at an altitude of 9,000 to 10,000 feet, the label 
bearing the collectors number 5,260. The other is by J. 
G. Lemmon, the locality not given, but only the year 1875; 
but I recall that in that year Mr. Lemmon collected chiefly 
in the mountains of southern California. 
A. ARNOGLOSSA. Stems a foot high or more, somewhat 
tortuous, striate, leafy to the middle, a pair of large bracts 
subtending the 1 to 3 short-peduncled heads: lowest leaves 
ovate-lanceolate, acute, 2 or 3 inches long, tapering to a 
broad or even distinctly winged petiole, the middle cauline 
as long, more lanceolate and spatulate, all remotely serrate- 
toothed, or dentate, or denticulate, or subentire, of very firm 
texture, deep-green above, pale beneath, sparsely scabrous 
on both faces, and with 5 strong parallel nerves very 
prominent beneath: peduncles and involucres glandular- 
puberulent, devoid of hairiness: rays 8-nerved, sharply 
and rather deeply 3-dentate: disk-corollas narrow, pubes- 
cent except the teeth; achenes hirsute; pappus white, 
rigid, serrulate. 
Black Hills of South Dakota, near Fort Meade, W. H. 
Forwood, 1887. Species perhaps somewhat local; certainly 
of very pronounced character; the leaves so strongly parallel- 
nerved as to recall those of certain species of Plantago.

A. TOMENTELLA. Two feet high, stoutish, pale and cine- 
reous, the foliage finely and closely tomentulose on both faces, 
the peduncles glandular-puberulent: leaves oval to ellipti- 
cal and elliptic-lanceolate, the largest 3 inches long, on 
petioles still longer, even the lowest cauline pair on elon- 
gated slender petioles, all remotely denticulate, the bract- 
like floral pairs lanceolate, sessile: heads about 5, large, 
on long naked peduncles: bracts of involucre biserial,
