Lawe (Abroma augustum)

Lawe or devil's cotton (Abroma augustum) is a plant species in Malvaceae, a small tree or bush that is erect, up to 10 m tall but generally 2-3 m tall, stems and twigs covered with star hair that are sharp, brittle and cause skin itching, sometimes also with glandular hair.

A. augustum has a single leaf, alternating, has a long stalk, a heart-shaped base, a pointed tip with a very variable base whose leaves near the base of the branch have a circular shape from the egg to the heart, 3-5 curves, diameter 20-37 cm, while the leaves near the tips of twigs have elongated shapes with smooth toothed edges.

The flowers gather in cymes at the tips of the twigs or face leaves, 1-4 buds, 1-3 cm long stems and 6-8 mm bractea. Hanging flowers, 3-5 cm in diameter, 5 angles and 1-3.5 cm long stems. The petals have 5 leaves, share a deep, triangular, 15-20 mm long, 6 mm wide and greenish.

The crown has 5 leaves, spoon-shaped, 2-3.5 cm long, 1 cm wide, dark purple or red or yellow, concave and white base, drooping and hanging. Stoneware-shaped stamens, 15 anthers that alternate between 3 anthers and 1 staminodium.

Square fruit, bell or cone upside down, have 5 wings, have a beak or not, the edges are broken showing space, the sides divide according to the bulkhead, 4-5 cm long and 3-4 cm wide. Cylindrical or breech-shaped seeds, 3-4 mm long, 2 mm wide and black.

Lawe grows wild along the water's edge, jungle bush, secondary forests, abandoned lands, the edge of the village, the edges of the road and railroad and open areas at an altitude of 0-1100 m, daily temperature of 27-30C in the month the hottest and minimum rainfall of 1500 mm/year.

Devil's cotton is widely cultivated for stems that produce fine fibers to be spun into clothing, fishing lines, fishing nets, hammocks and rope. The very fine fibers are painted and arranged as wigs.

Roots, stems, leaves and other parts produce medicinal ingredients to treat menstrual disorders, aphrodisiacs, anti-fertility, diabetes, cure gonorrhea, skin diseases and scabies. This species is sometimes planted as ornamental shrubs.

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 ...
