“Antennaria Hendersoni sp. nov. 
Loosely tufted, bearing at base ascending stolon-like branches 
3-6 cm. long; whole plant covered with a closely matted white to- 
mentum, which becoming slightly looser on the stem: flowering stems 
erect, 20-35 cm. high: basal leaves crowded, narrowly oblanceolate, 
not petioled, acute and often curved at tip, 15-30 mm. long, 3-4 mm. 
broad; cauline leaves scattered, linear-oblanceolate, acute, grad- 
ually reduced upward: heads numerous, rather loosely corymbed ; 
involucre 5-6 mm. high, woolly below; bracts pale, sometimes 
slightly brownish at base, the white papery tips rather obtuse and 
somewhat lacerate, the inner ones twice as long as the outermost : 
pappus white. 
Mt. Adams, Wash., Aug. 6, 1892, L. F. Henderson, 2290 in 
part; pistillate plants only. 
The species here proposed is clearly not referable to any hitherto 
Tecognized from the Cascade Mountains and does not agree with 
any described Rocky Mountain species. It is nearest perhaps to 
A. nardina Greene.

Whole plant silvery with a closely appressed tomentum, ap- 
Parently tufted, the woody base bearing leafy surculose stolons 
3-4 cm. long: flowering stems leafy to the inflorescence, erect, 
8-14 cm. high : leaves numerous, sessile, linear or linear-oblanceo- 
ate, acute, 2-5 cm. long, the lowest with broader somewhat 
“carious partly sheathing bases : heads in a single dense cluster or 
Corymbed : involucre oblong-cylindric, woolly only at the base, 
3-7 mm. high; bracts in several series, linear-lanceolate, acute or

Klickitat, Wash., May 15, 1882, Zhomas Howell (type) ; Little 
Klickitat Valley, Wash., May, 1880, Suksdorf, 283. (The locality 
and number of the Suksdorf specimen are open to question as it is 
Mounted with specimens of A. Janata Greene, the one label being 
“pparently a combination of two original ones.) Both collections 
are in the Gray Herbarium.
