An examination of the type specimen as well as the 

 original description shows that Mr. Watson took for the 

 type of his A. favescens what he has since regarded as 

 only a form of A . car idea and which certainly intergrades 

 with that species. The plants which he has referred to 

 this species, which grow at a lower altitude, are quite dif- 

 ferent and characterized by very short and hooked spurs, 

 very small flowers, hardly more than 6" long, always 

 yellow: upper leaves reduced to minute bracts; stems 

 very long, 1-3 long, slender, at least three times as 

 long as the short and small leaves. It is probable that 

 the labels of the two species have been changed in the 

 National Herbarium, but must have been changed bv 

 Mr. Watson himself before his descriptions were drawn 

 up, for the plant which he calls " subalpine " form is sel- 

 dom found higher than 7500 ft. altitude, but is common 

 as low down as 6000 ft. altitude along streams, while the
