Sea hibiscus (Hibiscus tiliaceus)

Waru or sea hibiscus (Hibiscus tiliaceus) is a species in the Malvaceae, a small tree, 5-15 meters high, the stem grows straighter and the crown narrower on fertile soils, while the trunk grows crooked and the crown widens on arid soil.

H. tiliaceus has leaves with long stalks. Strands circular or ovoid or heart shaped, flat edge, diameter up to 19 cm. Veins with glands at the base. The underside has gray hair. The supporting leaves are oval in shape, 2.5 cm long and leave marks at the ends of the branches.

The leaves contain saponins, flavonoids and polyphenols, while the roots contain saponins, flavonoids and tannins. This plant contains Cyanidin-3-glucoside as the main anthocyanin found in flowers. The leaves exhibited strong free radical scavenging activity and the highest tyrosinase inhibitory activity among 39 tropical plant species.

Light wood, quite dense, fine structure and not too hard. Bluish gray or pseudo purple or purplish brown or greenish. Tough and durable survive in the soil. Commonly used as building materials, boats, cartwheels, tool handles, carving and firewood. Bark is soaked and beaten to obtain fiber and rope for further use as the basis for making nets and bags.

Leaves for animal feed. Young leaves are used as vegetables and soy sauce fermentation process. The leaves are crushed to treat boils, hair fertilizer. Young leaves are boiled with sugar to dissolve phlegm in severe coughs. Leaf buds are used to treat dysentery and mucus in children. Root for fever medicine.

Yellow garden spider (Argiope appensa)

Yellow garden spider ( Argiope appensa ) is a species of spider in Araneidae that lives on the coast to forests on islands in the western Pacific Ocean. Black and yellow females are striking and have a length of 5.1-6.4 cm including long legs, while males are brown and have a length of about 1.9 cm. A. appensa lives on cliffs in the hills at 600 m above sea level in Kewu plain to rice fields in the lowlands. They make nests at a height of 1.5 meters from the ground between teak ( Tectona grandis ), sonokeling ( Dalbergia latifolia ), sonosiso ( Dalbergia sissoo ), crown flower ( Calotropis gigantea ) and various grasses. Yellow garden spiders grow in large sizes, but are not toxic to humans. Advanced builds ball-shaped nets and most of them make stabilizers which are zigzag-shaped lines in nets made of thicker bands. This species spends more time in stationary and sits in the middle of the net with its head down to wait for insects to be entangled in fine silk thread. Unli...

Skyflower (Duranta erecta)

Sinyo nakal or skyflower ( Duranta erecta ) is plant species in Verbenaceae, a broad shrub or small tree, up to 6 m high, stems growing upright or horizontally with broad clumps, many branches, bark light brown, old tree has axillary spines and grows to form dense colonies. D. erecta has bright green leaves, elliptical to ovoid, pointed or rounded ends, sitting opposite, 7.5 cm long, 3.5 cm wide, a main vein in the middle with several small lateral veins, petiole long 1.5 cm. Flowers are light blue or lavender or white, appear in tight clusters as on terminal stems and axils, often curled or pendulous, blooms in summer. The fruit is a berry having a stalk, small round, yellow or orange or white in color, up to 11 mm in diameter, an eye green in front and containing several seeds. Skyflower grows in dry or humid areas and lots of sun, rocky or sandy beaches, forests, farmland and disturbed places. Plants will grow at a rate of up to half a meter per year.

Big-leaved acacia (Acacia mangium)

Big-leaved acacia ( Acacia mangium ) is a species of woody plants in the Acacieae, long oval leaves, growing up to 30 m and straight stems, except in less favorable places will grow only 7-10 m, have hardwood, rough, longitudinal grooved and dark to light brown. A. mangium has shoots with compound leaves consisting of many minor leaves and after growing a few weeks does not produce any more real leaves but the main axis of the petiole of each compound leaves widens and turns into known pohyllocladus or pseudo leaves. Big-leaved acacia has about 142,000 seeds/kg. Long pods form circular threads and are black or brown when ripe. Dry pods will open to expose small black seeds. Trees bind nitrogen to the soil and are a popular species for agroforestry projects. This plant is weather resistant, although it requires special care if it is planted as a garden plant where the leaves are falling a lot. These plants include legumes that grow quickly by increasing height 4 m per year near ...
