Giant bamboo (Dendrocalamus asper)

Petung or bamboo betung or dragon bamboo or giant bamboo (Dendrocalamus asper) is a species of plant in the Poaceae, large and strong stems, high adaptability, used as building material and structural wood for construction and cooked shoots for vegetables.

D. asper grows in clumps, the shoots are purplish black and covered by blackish brown velvet. 20 m high with curved ends, 40-50 cm long, 12-20 cm in diameter and 1-4 cm thick. Green or dark green or purplish green or whitish green or mottled white by lichen.

Dlium Giant bamboo (Dendrocalamus asper)

The margins of the internodes are surrounded by hanging roots, the reed midrib 50x25 cm, covered by blackish brown velvet, the ears are rounded and sometimes curled to the base of the reed midrib leaf, 7 mm high with jute hairs up to 5 mm. Ligula serrated irregularly, 7-10 mm high with short bristles up to 3 mm.

The leaves of the reed midrib are triangular with a narrowed base and bent back. Leaves on twigs with loose midrib or sparsely pale, without ears, ligular 2 mm, strands 15-45x1-8.5 cm, slightly hairy underside and short petioles.

Flowers in panicles on leafless twigs with clusters of spikelets on each internode. The spikelets are ellipsoidal, 6-9x4-5 mm, flattened to the sides, have 1-2 gluma and 4-5 florets.

Giant bamboo grows best at an altitude of 400-500 m, average rainfall 2,400 mm/year, temperature 25F, likes lots of sun and moist and fertile alluvial soil, but is also able to grow up to 1910 m elevation and places dry.

Petung grows by spreading roots and rhizomes underground. The speed of spreading is determined by the type of soil and the local climate. Rhizomes in the soil can be cut if desired and if separated from the main clump they will usually die.

Thick, strong and durable stem at 8% moisture content has a wood density of 0.7-0.8 g/cm3, at 15% moisture content it has a fracture strength of 103 N/mm2, the compressive strength parallel to the fiber direction is 31 N/mm2 and the tensile strength is 31 N/mm2. shear is 7.3 N/mm2.

Bamboo betung is used as a building material and structural wood for the construction of a wide variety of buildings including house posts, boats, tobacco shed frames, bridges, waterways, musical instruments, furniture, household and handicraft utensils, laminated boards, pulp, chopsticks, toothpicks and etc.

The large and sweet shoots are favored by people for pickling and various dishes. The quality of these shoots is considered the best compared to shoots of other bamboo species as food ingredients, including when canned.

The crown is dense, dome-shaped and sheds leaves. The leaves are compound and pinnate oddly with 5-7 strands that have different sizes and appear alternately on the shaft. The leaves are round or elongated in width or heart, the upper surface is green and the surface is pale green. The flowers are small, 0.5-1 cm long and clustered in panicles. The pods are green to brown when ripe and are elongated lanceolate, pointed at the base and tip. The pods have 1-4 seeds which are soft and brownish. Indian rosewood grows at elevations below 600 m,

Soapbush (Clidemia hirta)

Senggani bulu or soapbush or Koster's curse ( Clidemia hirta ) is a species of tropical plants, perennial shrubs, grows as high as 0.5-3 m, but sometimes reaches 5 m in more shady habitat, young stems are round and covered with hair, stiff, reddish brown. C. hirta has simple leaves arranged opposite to the stem, oval-shaped in a wide line at the base with a pointed tip and almost entirely to a smooth jagged margin. The upper surface is rarely covered with hair, while the lower surface has thick hair. The leaves have a rather tangled appearance and five main veins are straight, curved and spread in parallel from the base of the leaf to the tip. Minor veins spread transversely and straightly that connect the five main veins. The flowers are arranged in small clusters at the ends of branches, growing on very short stems and having five white petals or sometimes pale pinks. The base of the flower is covered with a mixture of coarse and sticky hair, five sepals but these are ver

Melinjo (Gnetum gnemon)

Melinjo or belinjo or tangkil ( Gnetum gnemon ) is a species of gymnosperms in Gnetaceae, dioecious, tree-shaped, living wild but also widely planted in the yard as a shade or barrier where seeds, seed coat and young leaves are processed into food. G. gnemon is a tree and has a straight trunk, this is different from other Gnetum which is usually a liana. Annual plants with open seeds, do not produce true flowers and fruit. Fake fruit is basically a seed wrapped in a layer of aryl fleshy. Single leaf oval and blunt tip. Melinjo live for more than 100 years, 25 m tall and produce 80-100 kg of seeds per harvest. They adapt to a wide temperature range and are very easy to find in various areas except the coast. Grows in forests, plantations and home gardens. Plants are propagated by generative and vegetative methods. Belinjo can be found in arid, tropical regions and does not require highly nutritious soils or special climates. Grow on clay, sandy and calcareous soil at an altitude of
