This variety is nearest to § /r/c/^^c^/yA' Engelmann,^ which 

 has been named Anogra -pallida Engelmanni Small." The 

 description of this variety is meager, but the erect and nu- 

 merous branches of my specimen do not suggest " parce 

 ramosa," nor are the seeds obtuse, as stated on page 334, 

 Am. Journ. Sci. (II), Vol. XXXIV, under CE . albicaulis. 

 The leaves approach those of var. v bi'evifolia in size. 



The plate was made by tracing after a photograph. It 

 has, therefore, greater accuracy than would be possible 

 with an ordinary drawing. The flower, however, was drawn 

 from a dried specimen soaked and spread so as to show its 

 shape. 



Bigelovia graveolens appendiculata, var. nov. 



Plate VI, Fig. 3. 



Stems light green, slightly tomentose except at the densely tomentose leal 

 axils; leaves involute, becoming terete, mucronate; heads in rather few- 

 flowered, corymbiform cymes on pedicels, often divaricately spreading; bracts 

 of the involucre carinate, ciliate, and scarious on the margins, obtuse or acute 

 at the woolly apex; corolla with from one to four yellow, linear appendages 

 of various lengths on the tube, and a few cobwebby hairs on the border. 



This differs from all other forms of this variable species 

 in the peculiar appendages of the corolla-tube. They are 

 not transformed pappus bristles, being too far up on the 

 tube, rather appearing like an outside corolla, as if the 

 corolla were trying to become double. In other respects it 

 approaches var. hololeuca Gray.

 Habitat. — On the Canadian River. 



The fragmentar}^ specimen from the "White Sands" shows 

 but little variation from the type ; the heads are smaller than 

 those of any of the species represented in the Herbarium 

 of the California Academy of Sciences.
