Plants

We expect plants to start shooting and flowering earlier in the year as a result of global heating. Shifting climate may also expand or contract their distribution.

A densely branched shrub with a tea-tree aroma when crushed. Usually grows between 0.5 - 1 m in height. May reach 2 m tall in lower altitudes. Will usually grow along the ground or against rocks. Leaves Usually crowded, oblong, and do not spread very widely. Size approximately 2–4 mm long and 1 mm wide, thick, concavo-convex (concave on both sides) and pointed at ends. Flowers Solitary, white and have circular petals, 8 mm across. Usually appear between December and April.
Low, spreading shrub growing to 15 - 50 cm high and 1 - 1.5 m in diameter. Stems and branches are densely arranged and covered in small hairs. The hairs are white-grey or brown/tan towards the tip of the branchlets. Leaves The leaves are narrow-oblong in shape and between 1 - 3.2 cm long and 3 - 7 mm wide. The bases are round and the edges of the leaf are bent downwards. The upper leaf surfaces are green, nearly glossy, hairless and smooth with obvious veins. The lower leaf surfaces are covered with cream, pale tan or orange-tan hairs that become white or grey with age. The leaf stalks are between 2.5 - 3.7 mm long. Flowers Flowering occurs between October and December. Pea-like flowers have petals that are deep mauve in colour. The flowering parts of the alpine rusty-pods are stalkless and usually 2-flowered. The flower stalks are between 2 - 5 mm long.
Citrus sinensis Aranis trees grow in the tropics and subtropics. It is a recent introduction to many of the Pacific Islands and has become naturalised in Vanuatu. There are four varieties of Aranis in Vanuatu. The tree grows to 12 m and often has spiny stems. It can have multiple flowering periods in the tropics, including year-round. It is a very good source of Vitamin C. Leaves Leaves are 10 cm in length and dark green. The shape is elliptic (a flattened oval) to ovate (egg-shaped), with the margins irregularly crenate (scalloped margin) or crenulate (serrated margin). Flowers Flowers are fragrant, white and 2 to 3 cm in diameter. Fruit Fruits are generally 8 to 10 cm in diameter but can be smaller or larger. The fruit is mildly sweet to sweet. The peel is greenish yellow to bright orange. A thick skin adheres to the flesh of the fruit.
Large deciduous tree with yellow leaves in autumn, around 20 m high. Also known as the Desert Ash. Leaves are comprised of leaflets. Has brown buds in winter. Many flowers in spring and fruit. Leaves 14 - 20cm long, usually 5 - 7 (occasionally 13) leaflets, which are each 5 - 8 cm long and 0.7 - 2 cm wide. Serrated edges with pointed leaf tips. Bright and shiny green on upper side and dark and pale on underside. Flowers Many inconspicuous flowers with no sepals or petals. Red to purple anthers (pollen-bearing part of a flower).
The Greek "dios" means divine or god-like, and "pyros" means wheat, a reference to the fruit of the gods, as some of the members of the genus have tasty fruit. A small shrub-like tree with a height of 11 m. It also flowers and fruits as a shrub. Very dark, mottled grey to black bark on the trunk/body of the tree. Leaves Thick leathery leaves 7 - 9 cm long.
Musa acuminata Common names: Banana (Gros Michel?) – Local/Bislama names for the varieties: Vetaï tamouté (white man’s banana - Cavendish), Switi, Sweet Tuven, Wan Manis (one month), Franis (French), Mignonette (sweet) Bananas are thought to have been first domesticated in Southeast Asia. They are native to the Indo-Malesian, Asian and the Australian tropics. Bananas are widely distributed and cultivated throughout all Pacific Islands and are a staple food plant. They are a major crop throughout most of Vanuatu. Banana are giant herbs whose underground stem forms a false trunk which is 2-9 m tall at maturity. Bananas can be planted and harvested year-round. Leaves Wide-spreading and long leaves, up to 3.5 m in length and 65 cm in width. They are comprised of a stalk (petiole) and blade. Leaves are arranged in a spiral around the ‘trunk’. They are easily torn by wind. Flowers A vertical inflorescence (flower head) forms a cluster or bunch, that is arranged in a spiral. The axils (upper angle between the leaf stalk/branch and the trunk) has rows of flowers. Bananas have both male and female flowers. Female flowers can turn into fruit and are found closer to the leaves. The male flower is generally purple-red and is usually found below the bunch of fruits. Fruit Fruits grow in large hanging clusters (bunches) near the top of the plant. They are made up 10 to 20 tiers, which are called ‘hands’. Each tier can contain up to 20 fruit. Individual fruit are known as banana or ‘finger’. The fruit has a protective peel with long, thin strings running lengthwise between the peel and the edible inner portion. The end of the fruit has a small darker tip which is the remains of the flower. The fruit ripen to a full yellow colour at ambient equatorial temperatures.
The Black Wattle plays an important role in Australia's ecosystems. As a pioneer plant it quickly binds erosion-prone soil following bushfires. Like other leguminous plants, it fixes the atmospheric nitrogen in the soil. Other woodland species can rapidly use these increased nitrogen levels provided by the nodules of bacteria present in their expansive root systems. Hence they play a critical part in natural regeneration after bushfires. Spreading tree which grows to 5 - 15 m tall. Bark is smooth and of greenish-brown colour on young branches. Blackish and rough on trunk. Distinct yellow flowers in September to December. Leaves Fern-like bipinnate leaves (leaflets that are further subdivided in an arrangement of leaves on either side of the stem). Olive green in colour. Raised glands are present at the junction of and between each pinnae (little leaf). Flowers Pale yellow or sometimes cream coloured ball-shaped inflorescences (clusters of flowers arranged on a stem). Flowering occurs from September through to December. Highly perfumed.
Also known as Blueberry Lily, a long, feathery shrub with flowers sticking up above the leaves. Long green pointy leaves with vibrant blue to purple inflorescences (flower clusters). Grows up to 1.5 m high. Leaves Long, feathery, smooth green leaves. 15 - 85 cm long with 4 - 15 mm width. Pointy ends and long and stiff throughout. Can sometimes appear red towards base but this is rare. Flowers Flowers stick up above the leaves, consisting of 6 purple petals (7 - 12 mm length) and 6 stamens (pollen-bearing part of the flower) in a ring. These are long, thick and have brown to black tips with yellow stems.
Small to large tree with a variable height of 3 - 45 m and has a bole that is approximately 150 cm in diameter. It has deeply fissured, dark-grey to black coloured bark that appears quite scaly on older trees. Leaves Inclined to ascending, narrowly rounded, lance-shaped, straight to slightly curved. 3-5 raised main veins with numerous secondary veins. Flowers Pale yellow/golden to white clusters of 2 - 8 that flowers July – December. In Victoria, it flowers in August - October.
Shrub or small tree to 8 m high. Leaves Soft, drooping, mostly 10 – 25 cm long and 2 – 5 cm wide, oblong or lanceolate with woolly white underside. Flowers Yellow or orange flower clusters.
