Antennaria aureola sp. nov. 
Caules 10-20 cm. alti, in vastis, stratis coloniis generati, laxe 
vel appresse lanati. Stolones 2-6 cm. longi, foliosi. Folia caulina 
magis minusve acutula, 1.5-2.5 cm. longa, superiora quidem 
anguste lanceolata, inferiora latius lanceolata vel etiam spatulata. 
Folia stolonica’ 2-3 cm. longa, 5-8 mm. lata, cuneato-obovata, 
apice brevi et obtuso ornata, ambobus lateribus appresse et ob- 
stinate sericeo-tomentosa. Capitula 1-10, cylindrica, involucra 
feminarum 8-10 mm. alta, pedunculis 5-15 mm. longis. Bracteae 
florum femineorum nitore aureo in 4 series imbricatae, omnes 
apicibus longis acutis albis angustae, serie externa excepta cuius 
bracteae apicibus obtusis breviores et latiores sunt et maculam 
basilarem fuscam habent. Plantae stamineae ignotae. 
Stems 10-20 cm. high, growing in large, matted colonies, 
loosely or appressedly woolly. Stolons 2-6 cm. long, leafy. Stem 
leaves more or less acutish, 1.5—2.5 cm. long, the upper narrowly 
lanceolate, the lower more broadly lanceolate or even spatulate. 
Stolonic leaves 2-3 cm. long, 5-8 mm. wide, cuneate-obovate, with 
a short, blunt tip, densely and persistently silky-tomentose on 
both sides during the season, but after hibernation becoming 
green through partial loss of tomentum. Heads 1-10, cylindrical, 
pistillate involucres 8-10 mm. high, peduncles 5-15 mm. long. 
Inflorescence corytnbose. Bracts of the pistillate flowers of a 
golden lustre, inbricated in 4 rows, all narrow with long, acute, 
white tips, except those of the outer row which are shorter and 
broader, with obtuse tips and a brown spot at the base. Staminate 
plants unknown. 
Among the allies A. aprica Greene is a low plant, usually less 
than 10 cm. high, with pistillate involucres 6-8 mm. high, with 
sessile or subsessile heads and with generally obtuse pistillate 
bracts; A. oxyphylla Greene and A, obovata E. Nels. are much
