Number of Occurrences

3(B003); DAO-2; CAN-0 Canadian Museum of Nature records=CAN; Agriculture Canada, Ottawa = DAO; some duplication of records likely exists (H155).NWT flora map shows 2 localities south of Gr. Sl. Lake but specimens at DAO document two different collections: 12 km N of Ft. Norman, MacInnes, July 1984 ( 64 59N, 125 44 W) and Norman Wells Pipeline, 632 km S, at Trout R., Mac Innes, July 1985 (60 59N, 120 34W)(H155).

General Status Rank
Rank: 
Alien
Status Rank Description: 
Regional distribution but with only 4 documented occurrences (2 of these post 1980) and present in two ecozones(H155). May be native, certainly most sites appear to have been introduced, species is weedy and likes disturbances (H126)
S Rank: 
SNA
Decision Process Description: 
Drafted as sensitive by E. Haber in 2004 (H155). Changed to Exotic due to evidence that the taxon is introduced in the NWT (S Carriere 2006); Reviewed in 2010, no change.; Reviewed in 2015 by Marilyn Anions; no change
