Golden leather fern (Acrostichum aureum)

Golden leather fern (Acrostichum aureum) is a species of plant in the Pteridaceae, an upright shrub, grows in large clumps and forms round plots, 2 meters high, stems short and stocky, fibrous, covered with large scales and brownish or pale in color with a black center line.

A. aureum has compound, pinnate, leather-like leaves and is up to 3 meters long. The minor leaves are narrow oval to elliptical, blunt or rounded at the base, blunt at the tip, mucronate, 24-30 pairs, irregularly seated and sometimes loose, dark green, erect or curved.

Several pairs (5 pairs or more) of minor leaves at the tip are often fertile and rusty or brownish in color, with the underside covered by many large sporangia. Sterile leaves sit on the bottom, are longer, have blunt or rounded tips and a short, small tip protrusion.

This species grows in tropical and subtropical areas, damp lowlands, coastal areas, open mudflats, brackish swamps, mangrove forests, tidal streams and grows well in full sun.

Plants contain beta-sitosterol, alkaloids, flavonoids, phenolics, catechins, saponins, tannins, glycosides, terpenoids, steroids, amygdalin, arbutin, formic acid, oxalic acid, five phytosterols (stigmasterol, y-sitosterol, campesterol, cycloartanol, and 24- methylene cycloartanol), 2 sesquiterpenes ((2R,3S)-sulfated pterosin C, (2S,3S)-sulfated pterosin C), as well as 2 derivatives ((2S,3S)-pterosin C and (2R)-pterosin P).

Often used to treat poultices for wounds and boils, snake bites, syphilis ulcers, sore throats, chest pain, elephantiasis, constipation, diabetes, cloudy urine in women, fever reducers, worm medicine, stops bleeding and is an emollient.

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 ...
