Lessingia germanorum

Chamisso

Linnaea 4: 203, plate 2, fig. 2. 1829.

Staci Markos
Common names: San Francisco lessingia
Endemic
Treatment appears in FNA Volume 20. Treatment on page 455. Mentioned on page 453.

Plants 5–30 cm. Stems erect, tan to reddish-brown, glabrous or villous. Leaves: basal withering by flowering; cauline margins entire or dentate to pinnately lobed, faces eglandular, abaxial glabrous or villous. Heads usually borne singly, rarely in corymbiform arrays, at ends of branchlets. Involucres obconic to campanulate, 4–8 mm. Phyllaries purple-tipped, sometimes sparsely sessile-glandular, villous; inner scarious. Disc-florets 20–40; corollas yellow (tubes with brown-purple band inside); style-branch appendages ± truncate-penicillate, 0.1–0.4 mm. Pappi tan, equaling or longer than cypselae. 2n = 10.


Phenology: Flowering Jun–Nov.
Habitat: Remnant sand dunes in coastal scrub: of conservation concern
Elevation: 20–100 m
