Solidago guiradonis

Solidago guiradonis is an uncommon species of goldenrod known by the common name Guirado's goldenrod. It is endemic to the San Benito Mountains in the Central Inner California Coast Ranges of central California.

It grows in woodland and grassland habitat in serpentine soils rich in asbestos.


Solidago guiradonis is a perennial herb growing from a woody caudex, sometimes reaching heights well over one meter. The leaves are up to 20 centimeters long near the base of the plant and shorter farther up. They are linear to lance-shaped and have winged petioles that expand to nearly sheath the stem at the bases. The herbage is mostly hairless.

The inflorescence is a narrow cluster of a few flower heads. Each flower head contains many yellow disc florets and up to 10 narrow yellow ray florets each 1 or 2 millimeters long.
