Solidago glaberrima montana (A. Gray), comb. nov. 
to replace S. missouriensis montana A. Gray, vide Synoptical. 
Flora of North America, Vol. I., part II., page 155, (1888): 
Solidago perornata sp. nov. 
Caulis 7-10 dm. altus, gracilis, minutatim pubescens, parte 
infima denudata excepta, striatus, valde foliosus. Folia tenuia, 
membrancacea, tricostata, breviter pilosa et superne scabriuscula, 
subtus dense et adpresse puberulenta (et hoc eo magis in venis), 
lanceolata vel latiora, acuminata, sessila vel infima alato- petio- 
lata, supra caulem medium maxima, dentibus inaequalibus acute 
serrata. Inflorescentia racemos unilaterales, divaricatos, recur- 
vatos, gracillimos formans. Capitula 4 mm. alta. 
Stem 7-10 dm. high, slender, minutely pubescent, except — 
the lowest, denuded part, striate, very leafy. Leaves thin, mem- 
branous, triple-nerved, short-pilose and roughish on the upper 
side, closely and adpressedly puberulent on the lower surface,the 
more so on the veins, lanceolate or broader, tapér-pointed, sessile 
or the lower wing petioled, largest above the middle of the stem, 
sharply serrate with unequal teeth. Inflorescence in 1-sided, 
spreading, recurved, very slender racemes. Heads 4 mm. high. 
This species differs from S. dumetorum Ltunell, which has 
thicker and more scabrous leaves and an inflorescence with fas- 
tigiate, short branches and closely glomerate heads; from S. 
elongata Nutt., which has nearly glabrous, sub-entire, obscurely 
3-nerved leaves and an elongated panicle; from S. Prtchert Nutt., 
which has a stem glabrous up to the inflorescence, larger heads, 
and leaves more sharply serrate and glabrous except on the margins 
and on the midveins; and from S. satanica Lunell, which has its 
upper leaves sessile or short-petioled and densely cinereous- 
pubescent beneath and a very contracted, many-flowered pyr- 
amidal inflorescence with smaller crowded flowers, and it is exclu- 
sively a wood-land plant. 
The type was collected by me on the 18th of August, 1907, 
on an open sunny hillside not far from the foot-hills of the Turtle 
Mountains, Rolette County, near Dunsieth. 
Aster lautus sp. nov. 
Caulis 7-18 dm. altus, lineis pubescentiae longitudinalibus de 
foliis decurrentibus, praeterea glaber, parte inferiore una cum
