Gravelly plains, ou the Rio Colorado and the Mohave, and Providence Mountains (Coulter,

i'S. G. densifolia, Benth. A foot or two in height : stems virgate from a woody 

 base, leafy to the top : leaves rigid, linear, laciniate-pinnatitid or incised ; the short 

 Lobes few or several, subulate: Bowers numerous in a compact head: corolla over 

 half an inch in length, violet-blue, two or three times the length of the calyx (the 

 lobes 3 lines long) : anthers linear. — Hugelia densifolia (a short stout form) and

Dry hills, from Santa Clara Co. to the Mohave, and in Southern Nevada. 



* * Root annual : stems slender, at length loosely branched, a foot or less in height : 

 leaves and their few {if any) divisions filiform : flowers rather few in the small 

 clysters. 



29. G. virgata, Steudel. At first strict and simple-stemmed, at length branched 

 from the base or throughout, sometimes glabrate: tube of the blue corolla longer 

 than the calyx : anthers (when dry) linear, deeply sagittate, a line long : ovules 2 I 



5 in each cell. — Hugelia virgata, Benth. ; Hook. Ic. PI. t. 200.

30. Gr. floccosa, Gray, 1. c. Smaller than tie- preceding: leaves mostly entire : 



corolla about 1 lines long, blue or becoming white (probably never "yellow"): 



antlers linear-oblong (barely half a line in length): ovules 1 t i t in each cell. — 



Hugelia lutea, Benth. in Bot. Reg. GUia lutescens, Steudelj Benth. in DC. (But
