Polemonium pulcherrimum, HooTc. Bot. Blag. t. 2979. Rocky Mountains ; August. 
G-ilia pinnatifida, Nutt, in Herb. Acad. Philad.? In the Rocky Mountains, near the head 
of the Rio G-rande ; August. If this he a variety of Nuttall’s plant (which is Fendler’s No. 
655) it is remarkable for its much less lohed leaves ; those of the branches being mostly entire. 
Gtlia Gunnisoni, (n. sp.) : annual; stem paniculately much branched from the base, nearly 
glabrous, as are the leaves; the latter alternate and scattered, subulate-filiform, all entire, 
mucronate; the crowded bracts viscid-puberulent (like the hranchlets), subulate, with the di¬ 
lated lower portion viscidly villous-ciliate, mostly shorter than the flowers, which are capitate- 
clustered at the summit of the hranchlets; teeth of the calyx pungently pointed, a little shorter 
than the tube of the salver-shaped white corolla; stamens inserted in the sinuses of the corolla, 
rather shorter than its ohovate lobes ; ovules 2 or 3 in each cell. Sand-hanks of Green River, 
Utah; October. Root slender, evidently annual; the stems or branches 6 or 8 inches high. 
Leaves all alternate, slender; the cauline and rameal scattered, filiform; the lower nearly an 
inch long; the upper gradually reduced to small subulate bracts. Calyx somewhat pubescent. 
Corolla 3 to 4 lines long, the limb rather shorter than the tube; style pubescent below.

Abronia fragrans, Nutt, in Herb. HooTc.; HooTc. Keiv. Jour. Bot. 5, p. 261. Rocky Mount¬ 
ains; August. This is in Wright’s (1711) and several other collections, as well as in Geyer’s; 
hut no character of it has yet been published. It is distinguished from A. mellifera by its pure 
white “ porcelain-colored” flowers, scarcely winged fruit, and especially by the involucre, com¬ 
posed of very large, broadly ovate, scarious and white leaflets.
