Phyllanthus myrtifolius

Phyllanthus myrtifolius lies within the Euphorbia family of plants and the genus Phyllanthus contains shrubby plants and small trees from tropical and sub-tropical areas of the world. The flowers of Phyllanthus are typically small and are followed by small fruits. Some of the larger fruited varieties are eaten for their high vitamin content.
The Phyllanthus genus, originating from Southeast Asia, Australia, and the tropical Americas, contains several plants used for bonsai.
The plants prefer a moist soil mix, and will die if allowed to dry out completely. On repotting make sure to keep the roots moist or the plants will suffer. Drooping and dull colored leaves are present if the plant gets a bit dry. If allowed to get completely dry, it may die.

Dragon Fly ( Ophiogomphus susbehcha )

Dragonflies are valuable predators that eat mosquitoes, and other small insects like flies, bees, ants, and very rarely butterflies. They are usually found around lakes, ponds, streams and wetlands because their larvae, known as "nymphs", are aquatic.

Female dragonflies lay eggs in or near water, often on floating or emergent plants. When laying eggs, some species will submerge themselves completely in order to lay their eggs on a good surface. The eggs then hatch into nymphs. Most of a dragonfly's life is spent in the nymph form, beneath the water's surface, using extendable jaws to catch other invertebrates (often mosquito larvae) or even vertebrates such as tadpoles and fish.They breathe through gills in their rectum, and can rapidly propel themselves by suddenly expelling water through the anus. Some nymphs even hunt on land, an aptitude which could easily have been more common in ancient times when terrestrial predators were clumsier.

The larval stage of large dragonflies may last as long as five years. In smaller species, this stage may last between two months and three years. When the larva is ready to metamorphose into an adult, it climbs up a reed or other emergent plant. Exposure to air causes the larva to begin breathing. The skin splits at a weak spot behind the head and the adult dragonfly crawls out of its old larval skin, pumps up its wings, and flies off to feed on midges and flies. In flight the adult dragonfly can propel itself in six directions; upward, downward, forward, back, and side to side. The adult stage of larger species of dragonfly can last as long as five or six months.

Swietenia macrophila meliaceae

Swietenia macrophylla is a very large tree, reaching a height of 30-40 m and a girth of 3-4 m; in favourable conditions it can reach 60 m high and 9 m girth. Trunk straight, cylindrical, with a buttressed base; bark rough, flaking off in small patches. Leaves paripinnate, up to 60 cm long; leaflets 6-16, ovate, lanceolate, acuminate, slightly oblique, light reen or reddish when young, dark green and shining when mature, up to 20 cm long, with 8-12 pale, secondary nerves.
Flowers 8 mm across, in narrow supra-axillary panicles about 8-13 cm
long and fragrant; petals greenish-white, oblong, 4 mm long, rigidly pointed. Fruit a woody capsule resembling a large inverted club, about 12.5 x 7.5 cm, erect.

ECOLOGY
Swietenia macrophylla is found in all forest types, from the edge of the pine savannah to the climax rainforest, but mostly in mixed hardwood forest belts, along riverbanks, on deep alluvial soils of considerable fertility. It occurs scattered or in small groups, but densities of more than 4-8 trees/ha are rarely encountered. In tropical America, it is among the pioneer species reoccupying degraded agricultural land. It has been shown that teak is outcompeted by S. macrophylla in a mixed stand. In the Philippines, Swietenia macrophylla is reported to be very firm in wind, resistant to cyclones.

Ikan cere ( Paedocypris progenetica )

Ikan cere ( Paedocypris progenetica ) is an Indonesian genus of fish in the family Cyprinidae (which also includes carps and minnows). Previously the two species, Paedocypris progenetica and Paedocypris micromegethes were known.  third species was discovered in Bukit Bauk, Terengganu in Malaysia.

Paedocypris progenetica has been claimed to be the smallest known species of fish and vertebrate in the world. The smallest mature female measured 7.9 mm and the largest known individual 10.3 mm.

Umbrella tree (Terminalia Mantally)

Terminalia mantaly or Umbrella tree grows 10-20 m with an erect stem and neat, conspicuously layered branches. Bark pale grey, smooth and rather mottled. Leaves smooth, bright green when young, in terminal rosettes of 4-9 unequal leaves on short, thickened stems; length up to 7 cm, apex broadly rounded, base very tapered, margin wavy. Flowers small, greenish, in erect spikes to 5 cm long. Fruit small oval; seeds, about 1.5 cm long with no obvious wings.

Rumput Centotheca lappacea

HABIT Perennial; caespitose. Culms erect; 30–100 cm long. Ligule an eciliate membrane; 2–3 mm long. Leaf-blade base simple, or broadly rounded; asymmetrical. Leaf-blades lanceolate; 8–12 cm long; 15–20 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade surface glabrous, or pilose; with tubercle-based hairs.
DISTRIBUTION Africa: west tropical, west-central tropical, southern tropical, and western Indian ocean. Asia-temperate: China and eastern Asia. Asia-tropical: India, Indo-China, Malesia, and Papuasia. Australasia: Australia. Pacific: southwestern, south-central, and northwestern.

Messina Creeper ( Ipomoea cairica )

Ipomoea cairica  has palmate leaves and large, showy white to lavender flowers. Each fruit matures at about 1 cm across and contains hairy seeds.
Its native range is uncertain, though it is believed to originate from a rather wide area, ranging from Cape Verde to the Arabian Peninsula, including northern Africa. Because of human dispersal, it occurs today on most continents as an introduced species and is sometimes a noxious weed. It is a major problem along the coast of New South Wales. In the United States it occurs in Hawaii, California, all the gulf coast states, as well as Arkansas and Missouri.

Combretum constrictum

Burung Raja Udang ( Alcedo atthis )

Common Kingfishers are important members of ecosystems and good indicators of freshwater community health. The highest densities of breeding birds are found in habitats with clear water, which permits optimal prey visibility, and trees or shrubs on the banks. These habitats have also the highest quality of water, so the presence of this bird confirms the standard of the water. Measures to improve water flow can disrupt this habitat, and in particular, the replacement of natural banks by artificial confinement greatly reduces the populations of fish, amphibians and aquatic reptiles, and waterside birds are lost.

This species is resident in areas where the climate is mild year-round, but must migrate after breeding from regions with prolonged freezing conditions in winter. Most birds winter within the southern parts of the breeding range, but smaller numbers cross the Mediterranean into Africa or travel over the mountains of Malaysia into Southeast Asia.

Pokok Saga (Abrus precatorius)

This tree we know that High-climbing, twining, or trailing woody vine with slender herbaceous branches. Leaves alternate, petioled, 5-13 cm (2-5 in) long, even-pinnately compound with 5-15 pairs of leaflets, these oval to oblong, to 1.8 cm (< 1 in) long, with margins entire. Flowers shaped like pea flowers, white to pink or reddish, small, in shortstalked dense clusters at leaf axils. Fruit a short, oblong pod, splitting before falling to reveal 3-8 shiny hard seeds, 6-7 mm (< 1 in) long, scarlet with black bases.
