Columbia with thinner, nearly glabrous leaves, thus approaching S. californica closely, as 

 well as the alpine plant with thick leaves red-tomentose beneath. 



The character relied upon to separate M. allenii and M. occidentalis does not seem 

 valid. At least a duplicate type specimen in the National Herbarium has most of its 

 petals entire at apex. It is very cjuestionable, too, if the character upon which M. aequi- 

 dentata is based will suffice to distinguish it from M. allenii. Differences in the compact- 

 ness of the cyme are subject to the degree of maturity of the specimens and to the effects 

 of altitude and exposure.
