In 1897 P. A. Rydberg published in the "Torrey Botanical 

 Club Bulletin," XXIV, 252, a result of his study of P. viscosum 

 Nutt. After seeing the type he says it is much nearer related 

 to P. confertum than to P. humile. P. viscosum as described 

 by Gray in the "Synoptical Flora," on the other hancf,TB near 

 to P. humile and differs from the original description of P. 

 viscosum by Nuttall, especially in the calyx lobes which are 

 elongated-lanceolate according to Nuttall, and this character is 

 excluded by Gray. A specimen in the California Academy of 

 Sciences from near Lassen's Peak, collected by J. G. Lemmou, 

 No. 26, evidently near P. humile and here described, is probably 

 P. parvifolium Nutt. in manuscript.
