Annual or perennial herb
Stem ± erect, 20–60 cm
Leaf 10–25 mm, elliptic to ovate, gland-dotted
Inflorescence compound; flowers many
Flower: sepals ± 3 mm, narrowly lanceolate; petals ± 2 mm
Fruit ± 4 mm
Ecology: Streambanks, riparian woodland
Elevation: < 300 m.
Bioregional distribution: east-central Sacramento Valley, adjacent n Sierra Nevada Foothills (Butte, Glenn cos.)

Small plants approach robust, low elevation forms of H. anagalloides. Stamen number seems not to separate these 2 spp; needs study.
