viscosis, conicis, castaneis: stipulis angustis, 15 mm longis, caducis: 
foliis suborbicularibus, abrupte acuminatis integris vel serrulatis, tri- 
nerviis, glabris, subtus glaucis; sureulorum (fig. 6) majoribus basi trun- 
catis vel cordatis, serrulatis; petiolo limbo breviore vel eum aequanti; 
amentis masculis circa 4 cm longis, bracteis irregulariter laciniatis, 
sericeis (f. 3), 5 mm plus minus longis: amentis femineis circa 4 cm 
longis, bracteis laciniatis sericeis, 5 mm longis: cupula (f. 4.) 2 mm 
longa diaphana, basin versus valde angustata, stipitata, margine paulum 
eroso; stigmatibus sessilibus. — This species differs from P. tremuloides 
in its shorter and less dense aments, in its larger and more irregularly 
cleft bracts, in its larger anthers and the broader and shorter, somewhat 
translucent cupulae of the pistillate flowers. The leaves of P. tremuloides 
turn light yellow after frost, while those of P. aurea take on a golden 
or an orange hue. P. aurea forms forests throughout Colorado, Utah, 
and adjoining territory, at an elevation of 2400 meters and upward. —

p. 57. — Caules 5—10 dm. alti, dense et minutatim pubescentes vel 
scabri per totam superficiem, praecipue autem in parte superiore, striati, 
robusti, recti, valde foliosi. Folia firma, crassula, admodum tri-costata, 
ambobus lateribus scabra vel breviter pilosa, eoque magis in nervis stri- 
gosa, et per totam laminam inferiorem dense pubescentia, acuminata, 
lanceolata vel latiora, in parte dimidia marginis exteriore serrata, aspero- 
ciliata, media 1 dm longa, 2 cm lata. Capitula 4—5 mm alta (vel magis), 
in paniculum amplum, pilosum conferta. Bracteae involucri late lineares 
vel deltoideae, zona viridi media exornatae. — This plant belongs to the 
same group as S, elongata Nutt., which has nearly glabrous, sub-entire, 
obscurely 3-nerved leaves, an elongated panicle and linear-subulate in- 
volueral bracts, and S. Pitcheri Nutt., which has a stem glabrous up t9 
the inflorescence, larger heads, and leaves more sharply serrate and 
glabrous except on the margins and on the mid-veins, The S. Pitcheri 
of this region is not altogether typical. Specimens collected by me at 
Pingree, Stutsman County, are glabrous on the nerves of.the upper sides 
of the leaves, otherwise typical, and plants from other localities, as 
Turtle Mountains, Minot, Towner, Peninsula of Lake Ibsen, etc., have 
the mid-veins glabrous on both sides, [S. serotina Ait. (?). — Dakota: 
The plant here described grows in the rich soil of the outskirts and the 
thickly wooded parts of the Turtle Mountains, where the type was col- 
lected by the writer in Bottineau County on July 23, 1902.
