A type specimen of F. Calif arnica \'ar. Barclayana Benth.* in 

 the Herbarium of the British Museum is puberulous as described, 

 but does not show the very marked and conspicuous gold-colored 



glands of Fagonia 



Californica var. glutinosa Vail (Bull. Torr. 



Bot. Club, 22 : 229). The species is very variable and it is 

 doubtful whether any of the forms described deserve varietal rank.
