Hedychium flavescens, Zingiberaceae, 'awapuhi melemele (yellow ginger).  This scented ginger from India is used in lei construction.  A sphingid moth expired while "trapped" in the tube of the ginger corolla.  The moth's "tongue" was bent back on itself at the base of the tube so it could not be withdrawn.  Location: back of E-W Center dorms along Manoa stream.
Helianthus annuus, Asteraceae, sunflower.  Large herb from North America grown for its bright flowers and for its edible seeds which also yield oil for cooking.  Location: East-West Center dorms flower beds and gardens.
Heliconia psittacorum, Heliconiaceae, parrot's beak heliconia. Upright herb from tropical America, with erect flower stalks and green-tipped yellow or orange flowers. Location: Henke; Ewa of Hawaii Hall.
Hemerocallis lilio-asphodelus, Liliaceae, day lily. Herb from Europe and temperate Asia, with large yellow-orange, funnel shaped flowers that last only for a day. A popular garden plant. Dried flower buds (kim choi) are used by the Chinese to flavor food. Location: ?
Hemigraphis alternata, Acanthaceae, metal leaf. Creeping perennial herb from Java, very commonly used as a ground cover in Hawaii. The leaves are dark purplish in color. The flower are white and fairly small. Location: Entrance to Art Bldg.; makai of Gilmour.
Heritiera littoralis, Sterculiaceae, looking-glass tree, dungun. Tree from eastern Africa to Pacific islands; lower leaf surfaces with silvery scales; fruits woody, smooth, keeled, one-seeded. Location: mauka of Hemenway.
Hernandia ovigera, hernandia. Named after Francisco Hernand (1514-1578), a Spanish botanist who was highly paid for his research into American natural history, but whose labor did not yield fruits equal to the expenditure (compare the fruits of Hernandia). Handsome tree native to the East Indies, sometimes used for canoes. The seeds can be burned like kukui but with the production of much smoke.  1 - habit, 2 - leaf and fruit, 3 - fruit, smaller than expected, is found inside the inflated green (later pink) sphere, 4 - female flower, 5 - female flower, 6 - side view of open male flower and bud of female flower, note inferior ovary with sheathing connate bracteoles that eventually become the inflated sphere containing the fruit, 7 - male flower.  Location: Mauka-Ewa corner of Sinclair Library; Diamond Head end of Spalding.
HIBISCUS-Malvaceae. In the tropics, hibiscus is the connoisseur's flower with as many fans as the rose, the camellia, and the azalea all put together. There are over 150 accepted species with natives on every continent except Europe. The named hybrids between these would fill an encyclopedia. The hibiscus is the state flower of Hawaii and more than 33 varieties have been brought from other countries. By crossing these with one another and with three native species, more than 5,000 horticultural varieties have been produced (some kinds will not cross). Literally every known color is represented among the hybrids. The fragrant white Hibiscus arnottianus is from Hawaii. The cream H. venustus from Tahiti has been crossed with H. rosa-sinensis to produce flowers of incredible size--up to 10 inches across. Hibiscus flowers last only a day (or 2) at the most whether left in the garden or picked, and it makes little difference whether you put them in water or not.

Hibiscus arnottianus, Malvaceae, Hawaiian white hibiscus. A native shrub or tree with large white flowers, growing at altitudes between 1,000 and 3,000 feet. Location: St. John courtyard; hiking trails.
Hibiscus esculentus, Malvaceae, okra, gumbo, ladies finger. Shrub from tropical Africa; the fruits are very mucilaginous and are much used in soups under the name "gumbo," the Spanish word for okra. Location: East West Center Gardens behind dorms near Lincoln Hall (along Manoa Str.); Garden plot, Diamond Head of Krauss Hall.
Hibiscus rosa-sinensis, Malvaceae, red hibiscus, Chinese hibiscus, "shoe flower". Shrub from tropical Asia, now wide planted, frequently as a hedge. When crushed, the red flowers turn black, yielding a dark purplish dye that is used in India for blacking shoes. In China the dye is used for the hair and eyebrows. It is also used to color liquor and to dye paper a bluish purple tint, which reacts with litmus. Hawaiians eat raw flowers to aid digestion; the Chinese pickle and eat them. Location: Very common, e.g., Diamond Head - makai corner of Campus Center.
Hibiscus schizopetalus, Malvaceae, coral hibiscus, aloalo ko'ako'a. Shrub from E Africa with slender arching branches and pendant, red flowers with feathery reflexed petals. The pollen of this hibiscus is often used in Hawaii for producing new varieties. Location: Wist Annex.
Hibiscus tiliaceus, Malvaceae, hau. Possibly from the Old World, now widespread in the Pacific Basin, forming impenetrable thickets, mostly near the shoreline. The bright yellow flowers turn to bronze and crimson as the day passes. The light, tough wood was used by Hawaiians for outriggers of canoes. The bark fibers were used for ropes, net bags and tapa. The flowers were used as a medicine with laxative properties. Location: Longs-Safeway Manoa parking lot by KC drive in.
Hippeastrum reticulatum, Amaryllidaceae.  The two plants in the first photograph with red-margined white flowers probably represent this species.  The plants with solid red flowers likely are hybrids.  H. reticulatum is a bulb-bearing herb from southern Brazil.
Hiptage benghalensis, Malpighiaceae, hiptage. A woody climber from S.E. Asia clusters of pink to white and yellow fragrant flowers and 3-winged , helicopter-like fruits. Used medicinally in India. Location: Near Ewa-Mauka corner of "Chiller," Makai-Diamond Head of Thrift Shop.
