100 PITTONIA. 
SOLIDAGO BELLIDIFOLIA. Tufted decumbent stems 2 to 5 
inches high, these and the whole herbage glabrous except 
the sparsely scabrous leaf-margins and a few hairs at the 
base of the petioles: lowest leaves orbicular, the others suc- 
cessively round-obovate and spatulate-obovate, all coarsely 
crenate, on broad petioles longer than the blade, the upper- 
most narrower, cuneate at base and sessile: heads few, large 
capitate-clustered at summit of stem; bracts of involucre 
oblong-lanceolate, obtusish, in about 3 series, the margins 
of the inner scabrous-serrulate at tip. 
Collected by T. J. Howell, on Mt. Adams, Washington, 8 
Aug., 1882, and distributed for S. pumilus var. alpina. 
PoLEMONIUM LUTEUM. Perennial, a foot high, more or 
less, the stems arising singly from slender almost horizontal 
rootstocks, simple, or toward the summit sparingly branched: 
herbage glabrous, only the calyx and pedicels showing scat- 
tered short and slender tortuous hairs: leaflets oblong-lan- 
ceolate, scarcely acute, 1 to 1 inch long, rather crowded, in 
10 or 12 pairs: flowers mostly solitary or in pairs in the 
axils of the upper leaves, nodding on short pedicels: calyx 
nearly $ inch long, campanulate, cleft to the middle, the 
lobes triangular-ovate, acute: corolla yellow, campanulately 
spreading from a short tube, the whole more than 1} inches 
long and nearly as broad, the broadly obovate lobes either 
very obtuse, or very abruptly short-pointed. 
This is Mr. Pringle's n. 6930, from the Sierra de Pachuca, 
Hidalgo, Mexico, 1898, distributed under the name of P. 
grandiflorum, which is a villous-pubescent plant with long 
and not widely expanding blue or purple corollas. 
GERARDIA LANCIFOLIA. Annual, slender, 2 feet high 
more or less, and sparingly branched from the middle or 
from toward the base; herbaceous angles of the stem and 
branches, as also the leaf margins, delicately and sparsely 
scaberulous, the plant otherwise glabrous: leaves thin and
