About Hāhā
Hāhā (Cyanea fissa) is recorded as an established shrub on Kauaʻi. A tall, sparsely branched shrub, sometimes reaching five metres, with yellow latex. Its very long leaves narrow toward the stalk and have a hairy lower surface. Curved, hairy flowers are pale with purple lengthwise stripes. Ripe fruits are broad and reddish orange. Documented component of native vegetation; wild-population survival, recruitment and occupied vegetation cover provide measurable conservation endpoints.
Kauaʻi evidence
Established island occurrence follows the Bishop Museum checklist. Diagnostic morphology follows Smithsonian Hawaiian Flora; accepted identity follows Kew WCVP. Generated imagery is not occurrence evidence. Proposed monitoring endpoints are not reported observations, measured effects or causal findings.
