Appendix One hundred Pacific Island agroforestry trees (3)
21. Cassia spp.
"cassias," "shower trees"
spp. C. alata L. ("candle bush," "golden candelabra tree"); C. fistula L. ("golden shower tree," "Indian laburnum," "pudding-pipe tree"); C. glauca Lam. (syns. C. sulfurea DC. ex Colladon and Senna sulfurea DC. ex Colladon Irwin & Barneby) ("scramble-egg tree"); C. grandis L. f. ("pink shower tree," "horse cassia"); C. javanica L. ("pink and white shower tree," "pink shower tree"); C. siamea Lam. ("kassod tree")
The cassias are all recent introductions to the Pacific Islands; some species (C. fistula, C. glauca, C. javanica, and C. siamea) are native to tropical Asia, whereas others (C. alata and C. grandis) are indigenous to tropical America. They range from shrubs or small trees (C. alata and C. glauca) to large, spreading trees (C. grandis and C. siamea), with pinnately compound leaves; striking racemose clusters or racemes of bright yellow to pink, or pink and white, flowers, and short to long, seed-bearing pods. Occasional to common in home gardens and in rural areas; occasionally naturalized in poorly-drained areas, along streams, and in other disturbed sites. Planted ornamental and roadside trees; occasionally planted as shade trees; wood of some species used in general construction and as firewood; leaves of C. alata widely used as a cure for ringworm; flowers used in garlands.
22. Casuarina equisetifolia L.
"casuarina," "she oak, " "ironwood," "beefwood"
syn. C. Iitorea L.
spp. C. nodiflora Forst. f (syns. Gymnostoma nodiflorum [Thunb.] L.A.S. Johnson; C. vitiense L.A.S. Johnson); C. oligodon ("yar," PNG Pidgin); C. papuana S. Moore
C. equisetifolia indigenous to the Indian Ocean, South-East Asia, Malesia, northern Australia, and most parts of the western Pacific; possibly an aboriginal introduction in some areas of the eastern Pacific, and a recent introduction to Nauru and most of the atolls. Medium to large, hardwooded, fast-growing, pine-like tree, up to 20 m high, with numerous, short-lived, long, thin, drooping, needle-like, gray-green, photosynthetic branchlets; awl-shaped, scale-like leaves; and small, dull green ripening to brown, cone-like fruit. Common on rocky volcanic and limestone coastal areas and commonly naturalized or indigenous in sandy or limestone areas and on de graded, lateritic, highly-eroded interior areas and fern lands of many islands; a naturalized pioneer on some open-cast mined areas in Nauru; occasional in home gardens and urban areas. Formerly a sacred tree in eastern Polynesia, where it was planted in temple grounds; nitrogen-fixing tree, often planted or protected in garden areas; commonly planted as an ornamental, roadside tree, wind-break, or for coastal protection or reclamation; hard, durable wood favoured for general construction, wood carving, and the production of tools, war clubs, tape pounders, and canoe parts; an excellent firewood; parts used medicinally.
Other, more restricted species indigenous from New Guinea to New Caledonia and Fiji, but apparently a recent aboriginal introduction into the Eastern Highlands of Papua New Guinea (c. 1200 BP). Small to medium-sized trees, up to 20 m or higher, with slender, green branchlets (the distal branchlets quadrangular) bearing whorls of scale-like leaves. Common in garden areas and grasslands throughout highland New Guinea, either as nurtured spontaneous, or deliberately planted trees; common in home gardens and as individual trees or groves surrounding villages and ritual pig-killing sites in highland New Guinea; occasional in lowlands and degraded or ultrabasic upland areas in New Guinea, New Caledonia, the Solomon Islands, and Fiji. Tree commonly planted or protected as an improved fallow in highland New Guinea because of its nitrogen-fixing ability; occasionally planted to control erosion and as boundary markers; timber used for light construction, tools, weapons, fencing, and firewood; trees also important in garden magic and death rituals in New Guinea. (L.A.S. Johnson has reclassified the Fijian species as belonging to the genus Gymnostoma, thus indicating that a similar reclassification of other Pacific Island species might be expected.)
23. Ceiba pentandra Gaertn.
"kapok tree, "silk-cotton tree"
Indigenous to India or Africa; a pre-World War II introduction into most Pacific Islands. Tall, deciduous, soft-wooded, light-gray-barked tree, up to 25 m or higher, with a buttressed, commonly spiny trunk; palmately compound leaves; and oblongellipsoid, capsular, pendulous, 5-celled fruit filled with numerous long, soft, silky or cotton-like fibres. Common to occasional throughout most of the high islands, including raised limestone islands, in both home gardens and in rural areas, often along roads or bordering agricultural holdings. Planted ornamental or roadside or boundary-marker tree; light-weight timber used in light construction; fibre used for stuffing pillows and mattresses.

31. Coffea spp. RUBIACEAE
spp. C. arabica L. ("Arabian coffee"); C. canephora Pierre ex. Froehn. (syn. C. robusta Linden.) ("robusta coffee"); C. liberica Bull ex Hiern. ("Liberian coffee")
Indigenous from tropical west to east Africa; an early post-European-contact introduction to many islands; not found on atolls. Shrub or small tree, up to 3 m or higher, with dark green, glossy leaves; axillary clusters of fragrant white flowers; and ellipsoid or oblong, yellow turning bright red fruit, each containing two, deeply -grooved, ellipsoidal seeds. Occasional to abundant throughout the high-island Pacific, where it is cultivated by both smallholders and as a plantation crop under a range of shade trees, such as Erythrina, Albizia, and Leucaena; naturalized, and even invasive in some areas, such as in Samoa and the Marquesas. The major export crop in Papua New Guinea, where some 200,000 smallholder growers produced 70 per cent of some K117.5 million in export earnings in 1985; also an important cash crop in New Caledonia, Vanuatu, and Hawaii and a minor crop, mainly for local sale, in Fiji, Tonga, Western Samoa, the Cook Islands, and French Polynesia. The most important species is C. arabica, the mainstay of the Papua New Guinea highlands industry and which is grown in Vanuatu, Tonga, and Hawaii, whereas C. canephora is important in other areas of Papua New Guinea, New Caledonia, and some coastal areas. C. Iiberica does not seem to have become well established anywhere. Coffee leaf rust (Hemileia spp.), which led to the complete collapse of the coffee industry in Sri Lanka, and to which only C. canephora has resistance, is present in some parts of the Pacific and poses a serious threat to the Papua New Guinea coffee industry.
