Cicuta mackensieana Raup is the most widely distributed mem- 

 ber of the genus in the territory. The author first collected it at 

 Matanuska in 1922. The following collections have since been made : 

 Matanuska (1103) ; College, near Fairbanks (1258) ; Circle, on 

 Yukon River (2595) ; mile 312, Richardson Highway (2686) ; 

 Willow Creek, mile 92, Richardson Highway; Valdez (2888); 

 Unalakleet (5106) ; Eklutna (6940) ; Takotna (7352) ; Talkeetna 

 (7580). An immature specimen collected at Hope (6695) seems 

 to belong here.

Cicuta douglasii (DC.) Coult. & Rose seems to be confined to 

 southeastern Alaska. Collections were made at Lemon Creek (784) 

 and at Mendenhall (783), both near Juneau ; Haines (1570) ; Skag- 

 way (1733) ; and Echo Cove, Lynn Canal (6034). 



All specimens cited were collected by the author and are in 

 his herbarium now deposited in Iowa State College at Ames.
