ANTENNARIA COMPOSITE 329 



A. pedicellate Greene 1. 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, prominently 

 tomentose on both acei and thin: heads on slender ped eels of }£-\ inch 

 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, acutisli or obtuse: achenes obscurely 5 angled as well as very 

 imnutely and sparingly glandular. Blue mountains of Oregon, Cunck." 



A. umbrinella Rydberg. Canescent with a very short silky wool which 

 becomes floccose upon the stem and upper leaves : flowering stems slender, 

 4-10 inches 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# suffruteseens Greene 1. 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 emargtn- 

 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 

 wbite 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 f-tems 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. Fl. 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 beneath, 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.
