描述：

Hinahina or Hinahina k kahakaiBoraginaceae (Borage family)The variety is endemic to the Hawaiian Islands (Locally common on Niihau, Kauai, Oahu, and Molokai, but seemingly rare on Maui and Hawaii Island. It may have formerly occurred on Lnai and Kahoolawe)Photo: Oahu (Cultivated)Flowerswww.flickr.com/photos/dweickhoff/5188038768/in/photolist-...The Hawaiian name hinahina refers to gray or silverish gray foliage of this plant.When the leaves of kookolau (Bidens spp.) were not available, the leaves of hinahina k hakai were brewed as a tea and believed to be a tonic by early Hawaiians. Dried leaves were used in treatment of diabetes. Too, the leaves along with alena (Boerhavia spp.) were pounded together, water added, and drunk for curing paoao (childhood disease, with physical weakening), ea (thrush), and naeoik (severe asthma).The fragrant white flowers and the succulent leaves were used, providing a long-lived attractive lei by the ancient Hawaiians.Today, it is still used as a beautiful natural and native component of haku, though the readily available non-native Spanish moss (Tillandsia unsneoides), also called hinahina, is usually substituted.Hinahina k hakai was adopted in 1923 as the official flower and lei material for Kahoolawe, which is strange since it is not naturally found there, though it may have been in the past.EtymologyThe generic name Heliotropium is derived from the Greek helios, sun, and trope, turning, in reference to an erroneous belief that the flowers to turn to face the sun; leaves and flowers that do this are referred to as heliotropic.The specific epithet anomalum is from the Latin anomala meaning extraordinary or abnormal.The subspecies name argenteum means silvery.
