obscure; gland large, oblong or lunate, densely hairy and sur- 

 rounded by a few scattered hairs; anthers oblong, obtuse on 

 dilated filaments of nearly equal length; capsule narrow, 5-7 cm.

On open hills Newhall; Elizabeth ]>,ke; Ft. Tejon. This 

 appears to be the southern limit of this species, which extends 

 as far north as Vacaville^. ^Description from plants growing 

 at Elizabeth Lake. 



This species breaks into an infinite variety of coloration, the 

 markings assuming different tints or becoming obscured, or en- 

 tirely disappearing, the petals becoming self-colored, and of 

 various shades. An indefinite number of color- varieties might 

 be described; a few have received names.

 of these species. 



Ft. Tejon, Kern County.

BY I,OUIS A. GREATA. 



The somewhat peculiar appearances of the disk of a developing 

 head of Grindelia robusta directed my attention to the fact, that 

 the separation of the style-branches of the hermaphrodite florets 

 occurs in a different manner in different groups of the Com- 

 positae and an examination of a number of plants leads me to 

 believe, that this interesting feature is sufficiently constant to 

 form a simple and useful aid to classification in that admittedly 

 difficult Family.
