Tea plant (Camellia sinensis)

Teh or tea plant (Camellia sinensis) is a species where leaves and twigs are used to make drinks. White tea, green tea, oolong tea and black tea or red tea are produced by the leaves of this species, but are processed differently to obtain different levels of oxidation, while Kukicha is produced from twigs.

A small shrub or tree that is usually trimmed at the top to harvest leaves. Strong taproots, yellow-white flowers 2.5-4 cm in diameter and 7-8 petals. The leaves have 4-15 cm long, 2-5 cm wide and short white hairs at the bottom. Young leaves are light green and dark leaves are darker in color.

Four varieties are recognized. Of these, C. sinensis var. sinensis and C. sinensis var. assamica (JW Masters) Kitamura are most commonly used for tea, and C. sinensis var. pubilimba Hung T. Chang and C. sinensis var. dehungensis (Hung T. Chang & BH Chen) TL Ming are sometimes used locally.

Seeds are pressed or squeezed to get oil as a spice that has a rather sweet taste and cooking oil, while wood produces an essential oil that is used for health and beauty purposes.

Fresh leaves contain caffeine 4%. Leaves of different ages produce different qualities of tea. Younger leaves are more preferred, usually shoots until the first three leaves are harvested for processing. Harvesting is repeated every two weeks.

Tea plants are cultivated in tropical and subtropical regions with at least 50 inches of rainfall per year. Many high-quality teas come from a height of up to 1500 meters because these species grow more slowly and produce better taste. Plants will become trees if they grow wild, while cultivated tea plants will be routinely pruned.

Tea leaves are used in traditional medicine and other medical systems to treat asthma, angina pectoris, peripheral vascular and coronary heart disease. Tea extract has been a concern because it has antibacterial activity. Preservation of organic food processed and treatment of persistent bacterial infections is being researched.

A chemical component called epikatekin is being studied where in-vitro experiments can reduce bacterial immunity to antibiotics in Staphylococcus aureus. Drinking tea extract containing this component will increase the effectiveness of methicillin to kill invulnerable bacteria.

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 ...
