Cordyline fruticosa, Agavaceae, ti, ki. A woody stemmed candelabra shrub from SE Asia with large green or reddish or brightly variegated leaves, brought to Hawaii by migrating Polynesians. The leaves were used for a variety of purposes, including thatching, rain coats, food wrapping, and hula skirts. The Hawaiians used the root to make a beverage of low alcoholic content. After Cook's time, British sailors taught them how to make a more potent drink (okolehao). Location: St. John courtyard; along road, Diamond Head side of Hemenway.
Couroupita guianensis, Lecythidaceae, cannonball tree. Tree from Guiana with large, fragrant flowers borne on long tangled stems on main trunk below the foliage branches. Fruits spherical, cannon ball sized. Location: Makai of visitor's parking kiosk, Ewa-mauka of Bachman.
Crescentia cujete, Bignoniaceae, calabash tree. Small tree from tropical America with tufted leaves 2-6 inches long, and irregularly bell-shaped, two-inch-long, yellowish flowers sometimes veined with purple. The fruit may be up to a foot in diameter, and while initially heavy with wet pulp and seeds, dries hard, remains smooth, and becomes quite light. These may be cut and used as receptacles or may be used intact as hula rattles.  The fruits can be shaped during growth by tying string around them when young. The flowers open in the evening and are bat-pollinated where native.  The first two flowers were photographed just after opening at late dusk while the third was photographed at mid-day.  Location: Makai side of Campus Center.
