Bi.KPHARiPAPPUvS NKMOKOSUS Crceiic, Manual 200. 1894. 



No. 8556, collected May 23, about three miles beyond vSan 

 Mateo, San Mateo county, on the Half Moon Bay road, eleva- 

 tion 200 feet, on an open j^'-rassy bank, not very plentiful. The 

 given range is Mt. Tamalpais, Mt. Diablo, and the Berkeley 

 hills, Jepson does not record any additional stations, so ours is 

 a considerable extension of the range. 



IIELENIACEAE fam. nov. 

 Perennial herbs, or in a few cases snffruticose, sometimes 

 dotied with oil glands: leaves either entire or pinnately parted 

 or pinnatifid, especially the lower ones: bracts of the involucre 

 herbaceous or membranaceous, sometimes petal-like and colored 

 their margins and apices then scarious: receptacle destitute of 

 bracts, rarely with bristle-like chaff: rays present sometimes per- 

 sistent and papery, or wanting in some genera; disk flowers with 

 regular 4 to 5-toothed tubular corollas: pappus paleaceous or 

 aristiform, or sometimes rigid and bristly, rarely none. A fam- 

 ily confined chiefly to western America, some of the genera local. 

 It is composed of the genera which are included by most writers 

 in the tribe Helenioideae or Helenieae of the family called Com- 

 positae.
