Solidago lepida subsp. fallax

(Fernald) Semple

Sida 20: 1611. 2003.

Endemic
Basionym: Solidago lepida var. fallax Fernald Rhodora 17: 9. 1915
Synonyms: Solidago canadensis var. fallax (Fernald) Beaudry Solidago elongata var. fallax (Fernald) G. N. Jones Solidago lepida var. molina Fernald
Treatment appears in FNA Volume 20. Treatment on page 156. Mentioned on page 152, 155.

Distal cauline leaves: margins usually with 6–8 teeth per side. Heads in leafy, ± pyramidal arrays, branches usually ascending, not secund, sometimes spreading, secund, arching, little surpassing subtending leaves. Phyllaries: proximal margins sparsely, minutely stipitate-glandular. 2n = 18.


Phenology: Flowering (Jul–)Aug–Sep.
Habitat: Fields, thickets, roadsides
Elevation: 0–600+ m

Discussion

Subspecies fallax is considered rare in New Brunswick, and its status in Labrador is uncertain. Narrower-leaved plants of subsp. fallax with less leafy, more pyramidal arrays can be difficult to distinguish from Solidago canadensis var. canadensis. Hybridization between the two diploid taxa is likely. Ray laminae tend to be shorter in subsp. fallax than subsp. lepida.
