Native

G. modocensis Eastw.


Stem 10–34 cm, branches generally several, spreading from below, slightly cobwebby or glandular near base
Leaves: basal in rosette, strap-shaped, pinnate, lobes short, spreading, toothed; cauline clasping, generally deeply lobed
Inflorescence clustered in flower, loose in fruit; pedicels glandular; glands black
Flower: calyx gland-dotted, rib width > membrane, lobes erect or spreading in fruit; corolla 7–10 mm, tube included, purple, throat yellow, or midveins purple, lobes 2–3 mm, lavender; stamens, style, slightly exserted
Fruit < or = calyx
Chromosomes: 2n=36
