The variety is well-marked but its characters are superficial, and 
its range overlaps that of the typical form of the species. But I 
have not seen typical M. paniculata from Alaska. M. strigosa

Gard. ii. 181 (1901); and M. alaskana Eastw. Bot. Gaz. xxxiii. 287 
(1902), are all segregates, and, if I may judge from character alone, 
are not worthy eae moe

This species combines the characters of the northern M. pani- 
culata and its varieties with those of the southern M. franciscana, 
having the hirsutulous pedicels and panicled inflorescence of the 
former, but the calyx-lobes and leaves of the latter.
