Appendix One hundred Pacific Island agroforestry trees (6)

84. Saccharum edule Haask. POACEAE/GRAMINAE
"edible sugar cane inflorescence," "Fiji asparagus," "pitpit" (PNG Pidgin)

Indigenous to Malesia and possibly New Guinea; probably an aboriginal introduction to the Solomon Islands, Vanuatu, and Fiji. Large, perennial, sugar-canelike grass, up to 2.5-4 m high, with erect, yellow or green to reddish stems; nodes marked but obscured by leaf sheaths; leaf blades tapering to a sharp point; a soft, fibrous, white to light yellow, cigar-shaped inflorescence enclosed in non-opening, leaf sheaths. Common in garden areas and widely naturalized, often in extensive stands; common in poorly drained valley bottoms, alluvial plains, or low-lying sites. Commonly cultivated or wild supplementary food plant in Melanesia; unopened (aborted) inflorescence eaten roasted over an open fire or cooked in an earthen oven in the leaf sheathes, cooked in coconut milk, and made into curries by Indians in Fiji; inflorescence a major seasonal cash crop; cooked inflorescence canned commercially in Fiji.

85. Saccharum officinarum L. POACEAE/GRAMINAE
"sugar cane," "noble sugar cane"

Indigenous to Malesia or New Guinea; an aboriginal introduction throughout island Melanesia and high-island Polynesia and Melanesia to as far east as Hawaii and Easter Island; a recent introduction to Nauru and some atolls. Large, perennial grass, up to 4 m tall, with erect, unbranched, yellow or green to dark red or almost black, sometimes striped, stems; nodes close together at base of stems and more widely spaced distally; leaves, long, broad, overlapping at base; and a dense, long, erect or drooping, branched panicle bearing silvery white to pinkish flowers. Common in rural garden areas, often in contiguous stands, as an intercrop or border planting; common in home gardens in both rural and urban areas; uncommonly naturalized; present, but not wellestablished, on atolls. Plant of important ceremonial or legendary importance in many areas of the Pacific, such as in Tonga, where it is presented along with kava in ritual offerings, or Hawaii, where its flowering signals the onset of the octopus season; common supplementary food plant throughout the Pacific, for which numerous named cultivars exist in most localities; juicy stems chewed as a source of refreshment and energy; stems chewed for medicinal purposes in New Britain; chewing the fibrous cellulose is believed to keep teeth and gums in good condition; a major commercial export crop or for industrial processing into sugar for local consumption in Fiji, Papua New Guinea, and Hawaii, where interspecific hybrid cultivars (often crosses between the noble caneslS. officinarum and woodier, more disease-resistant, wild canes such as S. spontaneum L. and S. robustum Brandes and Jeswiet ex Grassl) are cultivated for this purpose; formerly cultivated commercially by the Japanese in the Marianas Islands; by-products of commercial sugar manufacture include molasses, which is fed to livestock, alcohol, which is made into rum, gin, vodka, and whiskey for export and local sale in Fiji, and fertilizer (mill mud); leaves of some varieties are used as durable thatch for roofing; leaves provide fodder for cattle in commercial sugar-cane farming areas of Fiji; fibre from flower stalk used in braided hats in Hawaii.
