Tliis is the common form of /'. riroiniana. It diflers from the type slightly in tlie 

 leaves, which are less siunately toothed. The original /'. rirghiiatia, d«-scril)ed and 

 figured by Miller, has deeply toothed leaves and the whole ])lant is nion^ or less 

 glutinous. It is a very rare form. 



The few poor specimens in this colle(t ion arc more or less i)ubesccnt, with sinii.itely 

 toothed or wavy-margined leaves, yellow fruit, and a pyramidal, angled, fruiting 

 calyx with a siinkeu base, a character which distinguishes all forms of this species 

 from /'. lamroUita M\. Lead City, altitude 1,600 in., .July 6 (No. 909).
