ANTENNARIA COMPOSIT A 329 
A. pedicellata Greene l.c.175 ‘‘Slender, more than a foot high, the 
stems with scattered spreading and rather conspicuous leaves instead of 
upright bracts: lowest leaves on short ascending branches hardly to be 
called stolons or surculi, small, oblanceolate, acute, nerveless, prominent] 
tomentose on both ‘ace; and thin: heads on slender pedicels of 4-1 inc 
in length, thus forming a lax subcorymbose cyme: involucres short and 
subcampanulate, their bracts in only about 3 series, the tips of the inner 
narrow, acutish or obtuse: achenes obscurely 5 angled as well as very 
imnutely and sparingiy glandular. Blue mountains of Oregon, Cusick.” 
A. umbrinella Rydberg. Canescent with avery short silky wool which 
becomes floccose upon the stem and upper leaves: flowering stems slender, 
4-10inches high from a shrubby branching base: leaves of the short sterile 
branches cuneate to spatulate, without any distinction of blade and petiole, 
4-6 lines long 1-3 lines broad at the summit, permanently canescent on 
both sides, persistent for several. years; leaves of the flowering stems 
oblong or narrower, erect, 3-8 lines long: heads few, sessile in a small cap- 
itate cluster: involucre campanulate, 2-3 lines high, its bracts broad and 
obtuse, the inner with conspicuous white tips: staminate plant not seen. 
On dry foothills of the Cascade mountains on the east side. Distributed 
by the author as A. dioica in 1881. 
A. suffrutescens Greene |. c. 277. Low evergreen undershrub, the rig- 
id procumbent branches leafy throughout, 1-3 inches long: leaves of the 
branchlets cuneate to spatulate, 2-6 lines long, obtuse and often emargin- 
ate, densely white-tomentose beneath, green and glabrate above; flower- 
ing stems slender, 3-6 inches long, with linear to subulate leaves and 1-5 
comparatively large heads at the summit: involucre campanulate, 4-5 lines 
_ high: bracts of the pistillate involucre narrowly lanceolate, the inner with 
white acuminate hyaline tips those of the staminate more ample, with ob- 
tuse Or emarginate to acute white tips: bristles of the pappus in the stam- 
inate flowers with evident though narrow and surrulate dilated tips. On 
rocky slopes of the Coast mountains in Josephine Co. Oregon. 
A. Howellii Greene 1. c. 174. A. plantaginifolia of authors as to the 
Pacific Coast plant. Freely surculose by slender stolons, the offsets bien- 
nial: flowering stems slender, 6-18 inches high, loosely woolly, bearing 
linear or lanceolate leaves and a cluster of several heads: radical leaves 
broadly spatulate to oblanceolate, acute or acutish and apiculate, attenu- 
ate below to a short petiole, 1-2 inches long, somewhat fleshy, canescent 
beneath, green and glabrate above: involucre campanulate, about 4 lines 
long, its bracts linear-lanceolate, the inner with very acute almost hyaline 
white tips: achenes oblong, pappillose-granular. Common in dry open 
grounds, western Oregon to Brit. Columbia. 
+ + Heads loosely paniculate : involucre almost glabrous. 
A. racemosa Hook. FI. i, 329. Freely surculose by long and slender, 
sparsely leafy stolons, lightly woolly, becoming glabrate: flowering stems 
6-20 inches high, slender sparsely leafy, bearing few or numerous, racem- 
- ously or paniculately disposed heads, nearly all slender-peduncled : leaves 
thin, the radical broadly oval, acute at each end, slender-petioled, includ- 
ing the petiole 1-3 inches long, obscurely 3-nerved at base, rather veiny, 
densely tomentose beneatl:, green and glabrate above: cauline leaves sim- 
ilar but smaller and sessile, lanceolate: involucre campanulate, about 3 
lines high; its bracts green or brownish; of the staminate heads obtuse, 
the inner obscurely white-tipped; of the pistillate heads narrow and most- 
- lyacute, with scarious white tips: Moist woods and rocky banks, Oregon 
to Brit. Columbia and the Rocky mountains.
