western oxeye
[This taxon is excluded from Washington]

Publication: Rhodora. 44: 340. 1942.

Origin:

Notes: voucher? only WA report Kz99 "pers com"
BC report from 1904, as var. scabra (Douglas et al. 1989), surely = var. occidentalis.

FNA21:"Variety scabra is reported as introduced in British Columbia, Newfoundland, Prince Edward Island, and perhaps Quebec (H. J. Scoggan 1978–1979, part 4).

Varieties (subspp.) scabra and occidentalis intergrade so completely and intermediate plants are so numerous that it seems futile to draw taxonomic lines. In general, some plants traditionally treated as var. scabra (in the strict sense) have somewhat narrower leaf blades and longer petioles than most plants treated as var. occidentalis."
