Mrs. Ferris, |. ec. 407, wrote “ A. viscida in Shasta and Plumas 
counties is inconspicuously glandular-pilose as compared with the — 
typical form and approaches A. tenuis, to which this species is 
very closely related.” The chief distinction, however, between “ 
these species has been found in the character of the bracts, those 
of A. viscida being three-parted. Unfortunately plants exhibiting — 
both entire and divided bracts have been found, for instance 
Heller’s number 11,586 from Butte County. Howell’s plant is — 
best treated therefore as a geographical variety of C. tenuis gen- — 
erally distinguishable by the parted bracts and mostly of more 
northern range although it meets the range of C. tenuis in Butte 
and Lassen Counties. =

This species differs from C. al and C. tenuis, var. viscidus ' 
in the dense pubescence which is very long and harsher than in 
either of the other species. From the former, which it resembles 
most in aspect because of the relatively broad leaves, it also differs 
constantly in the tripartite bracts. In this respect it resembles | 
C. tenuis, var. viscidus but the divisions of the bracts are more : 
nearly equal and the leaves are relatively broad. C. Hanseni, PR
