CAUFORNIAN ASTERACE)^. 25 



New Californian Asteraceas. 



CoRETHROGYNE FLOCCOSA. Evidently large and bushy, 

 perhaps shrubby at base; stem, branches and leaves silvery- 

 hoary with a light floccose tomentum : cauline and rameal 

 leaves oblong, obtuse, sessile by a cordate-clasping base, entire 

 below the middle, above it sharply cut into close spreading 

 serrate teeth : heads many, scattered singly at the ends of 

 filiform twigs, the whole forming a large loose corymbose 

 panicle, the pedunculiform twigs not floccose but green and 

 rough with short gland-tipped hairs : involucres turbinate, 

 less than /^ inch high, their well imbricated bracts glandular- 

 scabrous and viscid, their tips subsquarrose : rays deep-purple ; 

 achenes silky, crowned with dark red-brown pappus. 



Collected at Elwood, near Santa Barbara, Sept. 1908, by 

 Miss Eastwood. 



CORETHROGYNE SCABRA. Suffrutescent, with rigid upright 

 stems 2 feet high or more, leafy up to the not very ample virgate 

 panicle : herbage wholly devoid of wool or hoariness, except 

 as to basal part of stem when young, all parts in maturity 

 dull dark green and very scabrous : leaves oblong-lanceolate, 

 1-1/^ inches long, sessile, acute, sharply and evenly serrate 

 above the middle : branches of panicle widely spreading, 

 mostly monocephalous : involucres almost campanulate, less 

 than y^ inch high, their many imbricated and squarrose bracts 

 viscid-scaberulous : rays short, red-purple: achenes cuneate- 

 linear, .silky ; pappus fuscous. 



L,os Angeles Co., collected by H. E. Hasse in 1890; again 

 at Griffith Park, and on Cahuenga Hills, in 1902, by Ernest 

 Braunton ; though specimens from Cahuenga Hills do not 

 agree as to inflorescence, and may, perhaps, represent a second 

 species marked by this lack of woolliness. 



CoRETHROGYNE SESSii,is. Branches, tall, erect, simple, 

 leafy to the summit, the whole plant even to the involucres 

 white with a thin tomentum : leaves thin, oblong-oval, sessile 

 by a broad cordate-clasping base, 1/^ inches long or more,
