RyDBERG: Rocky MOouNTAIN FLORA azo 
at all agree with a duplicate of the type of A. pulcherrima in the 
Torrey herbarium. In the latter, the bracts are imbricated in 
6 or 7 series, wholly brown, the innermost very narrow and 
acuminate. A. foliacea Greene is wholly ignored, although E. 
Nelson had it in his paper. A. Sierrae-Blancae Rydb. is made a 
synonym of A. rosulata, although the words “leaves glabrate 
above” are added after the reference. Probably the authors had 
not seen any specimens. The characters of the bracts (not referred 
to) are a better distinction than the mere lack of tomentum. On 
the other hand, Antennaria oblanceolata Rydb. is kept distinct from 
the closely related A. luzuloides. In the key the latter is placed 
under the heading “bracts tomentose except the scarious tips’; 
but in the description is stated ‘‘involucres glabrous nearly or 
quite to the base.’’ The latter characterization is correct and 
A. luzuloides should be associated with A. oblanceolata instead of 
A. pulcherrima in the key. 
‘ Antennaria acuta sp. nov. 
A surculose-stoloniferous perennial; stems slender, 5-12 cm. 
high; stolons short and mostly ascending; basal leaves and those 
of the stolons narrowly oblanceolate, greenish-white, tomentose 
on both sides, glabrate in age, 15-25 mm. long, 2-4 mm. wide, 
acute or abruptly short-acuminate; tomentum very fine and ap- 
pressed; stem-leaves narrowly linear or linear-oblanceolate; heads 
3-5, conglomerate, sessile; involucres about 6 mm. high, tomen- 
tose below; bracts of the pistillate heads lanceolate to linear- 
lanceolate, dark greenish brown with slightly lighter tips, the 
Inner acute 
This is related to Antennaria alpina and A. media. It resembles 
perhaps most the former but the leaves are equally tomentose on 
both sides. From A. media it differs in the narrower, acute or 
acuminate leaves with a finer, closely appressed tomentum.
