| 説明 | Koʻokolau or Koʻolau Range beggarticksAsteraceae (Sunflower family)Endemic to the Hawaiian Islands (leeward southeastern Koʻolau Range, Oʻahu only)ʻAiea Loop Trail, OʻahuWoody trunkEarly Hawaiians used the leaves in hot teas and tonics. Today, all species of koʻokoʻolau can be brewed as a tonic and each are said to have distinct flavors. Regarding Bidens spp., Isabella Abbott comments that "I find that the roughly half a dozen species common in Hawaiʻi offer two or three slightly different flavors, each a bit more subtle than commercial black tea." ("Lāʻau Hawaiʻi: Traditional Hawaiian Uses of Plants")EtymologyThe name Bidens is derived from the Latin bi, two, and dens, teeth in reference to the pappus awns or collective bristles on the achenes (fruit, seeds).The specific epithet asymmetrica is from the Greek asymmetricus, irregular or lacking symmetry.nativeplants.hawaii.edu/plant/view/Bidens_asymmetrica |
