Mexican sunflower (Tithonia diversifolia)

Paitan or Mexican sunflower (Tithonia diversifolia) is a plant species in Asteraceae, shrubs with 2-4 meters high, abundant yellow flowers, fast growing, tolerant to high canopy density with deep roots and widely used as a barrier to erosion, insulin and green fertilizer.

T. diversifolia grows upright, erect stems are tubular and green woody. Single leaf arranged alternately, length up to 32 cm, width up to 25 cm, sharp edges and base, pinnate bones, rough surface and green. Young leaves have a tip, while adult leaves have 3-5 ends.

Compound flowers grow at the end of branches with long stems. Petals are tubular, smooth hair and green. Crown will be separated, ribbon-shaped, yellow and smooth. Yellow round stamens and curved pistils are yellow.

The fruits are round, light green and turn brown when ripe. The seeds are round, have four corners, 5 mm long, hard and brown in color. Seeds spread by the wind. White taproot.

Mexican sunflower grows wild on the edge of farmland, cliff slopes and highway edges. Fertile breeds at altitudes 550-1950 m, annual temperatures 15-31C, annual rainfall 100-2000 mm and lots of sun.

Paitan is widely used as an organic fertilizer to support growth, reduce pollutants and reduce the level of active P, Al and Fe giraffe. Leaves to reduce blood glucose levels in diabetics, treat itching and scabies, oxidize bacterial skin cells and prevent fungus.

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 ...
