RypBERG: Rocky MOUNTAIN FLORA 651 
thin, glabrous on both sides; inflorescence paniculate ; branches 
arching and secund; heads numerous, 3-4 mm. high; bracts 
linear or linear-lanceolate, acute; rays I-1.5 mm. long, less than 
0.5 mm. wide; achenes hirsutulous. 
This is closest related to S. canadensis, but differs in the gla- 
brous leaves and the less pubescent stem. It may also be con- 
fused with S. serotina and S. elongata, but the former has much 
larger heads, fully 5 mm. high, and in the latter the inflorescence 
is narrower, rhombic in outline and with ascending scarcely arched 
branches.

v Solidago polyphylla sp. nov. 
Tall, sometimes a meter high; stem strict, simple and puber- 
ulent up to the more hirsutulous inflorescence ; leaves narrowly 
lanceolate, sessile, acute at the base, acuminate at the apex, dis- 
tinctly triple-nerved, serrate above the middle with small distant 
teeth, thick and firm, green, scabrous above, more softly short- 
pubescent beneath ; inflorescence panicled ; branches more or less 
arching and secund ; heads about 5 mm. high ; bracts ee acute ; 
rays I1.5—2 mm. long, 0.5 mm. wide; achenes hispidulou 
This species is closely related to Ss procera and has isn mis- 
taken for it. It differs from that species in the larger heads (in 
S. procera only 3-4 mm, high), the more compact inflorescence, 
the more toothed upper leaves and the shorter pubescence on the 
stem and lower leaf-surfaces.

Solidago viscidula sp. nov. 
Low, about 2 dm. high; stem finely pubescent, reddish ; basal 
~ leaves and lower stem-leaves narrowly linear-oblanceolate, finely 
puberulent and somewhat viscid, denticulate, obtuse or acutish, 
indistinctly triple-veined ; upper stem-leaves sessile ; inflorescence 
Paniculate but flat-topped, branches scarcely secund; heads 
Numerous, small, about 5 mm. high ; bracts linear, obtusish, viscid ; 
rays pale, about 2 mm. long and 0.5 mm. wid 
This is closely related to S. missouriensis, but is distinguished 
_ by the viscid inflorescence and the indistinctly triple-nerved leaves.
