Eastwoodiella californica (Swamp harebell) is a native California herb in the Campanulaceae family, recognized by Monotypic genus endemic to coastal northern California marshes.
Swamp harebell is a rare (CNPS 1B.2) California native perennial found in southern Northern Coast and northern Central Coast bioregions in marshy areas at elevations up to 400 meters. Flowering from June to September, this plant produces pale blue flowers in bell-shaped corollas 8 to 15 millimeters long with reflexed lobes. Growing with clambering stems 10 to 30 centimeters tall that have stiff, recurved hairs along stem angles, it develops thin, elliptic to ovate leaves 10 to 20 millimeters long with crenate or irregularly serrate margins. Its leaves are arranged with short or absent petioles, and individual flowers emerge singly at each node. The fruit is spheric and weakly ribbed, with basal pores containing small elliptic seeds less than one millimeter long.

How to tell it apart
vs Campanula: Eastwoodiella is a slender clambering bog plant with stiff, backward-hooked (recurved) hairs along the stem angles, leaf margins and ovary ribs; true Campanula is mostly erect and either glabrous or evenly soft-hairy without hooked bristles.; vs Githopsis: Eastwoodiella has a bell-shaped corolla with reflexed lobes and a many-seeded capsule; Githopsis (bluecup) has a narrow, sharply angled calyx tube and a small erect blue flower.; vs Heterocodon: Eastwoodiella is a perennial with true open bell flowers; Heterocodon is a tiny annual with round clasping toothed leaves and mostly closed (cleistogamous) flowers.; vs Triodanis: Eastwoodiella flowers are pedicelled bells; Triodanis (Venus's looking-glass) has sessile flowers crowded in the leaf axils, the lower ones closed.; vs Wahlenbergia: Eastwoodiella has recurved bristly hairs and weak clambering stems; Wahlenbergia is a rhizomatous plant with erect glabrous stems and a top-opening capsule.
