348 PITTONIA. 
6, glomerate and sessile in flower; bracts of the involucre 
with obovate retuse or emarginate white tips: widely dilated 
tips of the pappus-bristles rather sharply serrate. 
Very plentiful in open woods, among rocks, in the lime- 
stone region of southern Illinois, near Cobden, F. S. Earle, 
30 March, 1879, male plant, in flower only; also the mature 
foliage from the same locality, collected by the present 
writer in June, 1898; and again in similarly mature sum- 
mer foliage from the other side of the Mississippi, in Mis- 
souri, 1898, B. F. Bush. Related to the exclusively Southern 
A. solitaria. 
PYRROCOMA GENUFLEXA. Glabrous, slender and low, the 
subseapiform stems usually monocephalous, upright from a 
short and strongly decumbent base, only 6 to 10 inches high : 
radical leaves unknown, the cauline few and small, even 
bract-like, linear-lanceolate, entire, sessile by a somewhat. 
clasping base: involucres campanulate, ? inch high, their 
ample and much imbricated bracts erect, spatulate-oblong 
and with eonspicuous oval euspidately mucronate green tips : 
rays numerous but short and suberect, saffron-color. 
Near Flagstaff, northern Arizona, 5 Sept., 1894, J. W. 
Toumey ; labelled “Aplopappus croceus,” though the species 
is not very nearly related to P. crocea. Its rays, though 
saffron-colored, are short and inconspicuous, while in its 
other characters the plant more nearly approaches some 
Oregonian members of its genus. 
SOLIDAGO SUBVISCOSA. Rigid but rather slender, erect, a 
foot high, very leafy up to the small close paniele or thyrsus 
of few and large heads: lowest leaves not known, those of 
the stem lanceolate or ovate-lanceolate, acute, entire, green 
on both faces but scabrous and somewhat glandular, the 
margins scabrous-ciliolate: heads 10 to 18 or more, about 1 
inch high ; bracts of involucre remarkably few and little im- 
bricated, largely green-herbaceous, acute and some recurved 
at tip, scabrous and viscid: rays rather many, and long, | 
deep-yellow. ce
