Recent taxonomic treatments have expanded the concept of S. velutina to include S. californica and S. sparsiflora, long considered by many to be distinct species.[3][6] These are now often treated as subspecies:[3]
- Solidago velutina subsp. californica (Nutt.) Semple - California, Oregon
- Solidago velutina subsp. sparsiflora (A.Gray) Semple
Another infraspecific taxon is also recognized by some authors:[1]
- Solidago velutina var. nevadensis (A. Gray) C.E.S. Taylor & R.J. Taylor
Description
editSolidago velutina has a basal rosette of leaves that are still present at flowering time. The leaves get progressively smaller higher up on the stem. Each leaf has three prominent veins running from the base to near the tip. One plant can produce as many as 500 small yellow flower heads in a large, branching array at the top of the plant.[3]
Galls
editThis species is host to the following insect induced galls:
- Asteromyia carbonifera (Osten Sacken, 1862)
- Procecidochares anthracina (Doane, 1899)
- Rhopalomyia cruziana Felt, 1908
