Location: Honolulu gardens.

The white sap is highly poisonous, providing toxin for an arrow poison used in east Arfica.

Leaves small, narrow, the petioles narrowly winged. Three major types include: 1) Tangerine (erroneously called mandarin orange), with deep orange-red skin; 2) Mandarin orange, with yellow or very pale orange skin; and 3) Satsuma orange, mostly grown in Japan. Location: Henke Hall, makai end of Ewa court.
Citrus sinensis, Rutaceae, sweet orange. Tree from S. China, introduced into Europe late in the 15th century. Columbus took orange seeds to Haiti in 1493. Brought to Hawaii in 1792 by Vancouver, who got the seeds from the Cape of Good Hope. Most of today's Kona oranges are probably descendants of this early introduction. Leaves not hairy, the petiole narrowly winged. Location: Henke Hall. Several other citrus trees are commonly grown in Hawaii but may not be found on campus. These include Citrus aurantifolia, the lime (very thorny shrub with the smallest flowers and fruits of the major species); C. limonia, the lemon (the leaf petioles not winged); C. grandis, the jabon or pummelo (young stems and lower leaf surfaces hairy, petioles broadly winged); and C. paradisi, the grapefruit (leaves and stems not hairy, petioles winged).
