Tali bamboo (Gigantochloa apus)

Tali bamboo (Gigantochloa apus) is a plant species in Poaceae, the reeds grow upright and tall with a shady canopy in the colony and form very tight clusters, the leaves grow at the end of the stalk, widely used as raw material for making handicrafts.

G. apus grows in clumps, tight and erect. Bamboo shoots are green, covered with brown and black miang hairs. The reed is cylindrical, straight up, 22 meters high with a curved tip and begins to form branches at 1.5 m above the ground.

Dlium Tali bamboo (Gigantochloa apus)


The reed has a diameter of 4-15 cm, has segments with a length of 20-60 cm, a wall thickness of 1.5 cm, the outer surface is gray or light green or yellowish green, the inner surface is white or yellow or brown.

The frond does not fall out quickly, is trapezoidal, 7-35 cm long, 8-26 cm wide, green and turns yellowish brown, the outer side is covered with dark brown miang hairs which then fall out when the midrib dries.

The midrib is triangular in shape with a narrow base, 3-10 cm long, 2-5 cm wide and curved back. The frond ears are like a frame, 4-8 mm wide, 1-3 mm high and up to 7 mm bristles. The ligula is serrated, 2-4 mm high and locos.

The leaves on the twigs are lanceolate, 13-49 cm long, 2-9 cm wide, the underside is slightly hairy. The frond ears are small and rounded, 1-2 mm high and lokos. Ligules are flat, 2-4 mm high and locos.



Inflorescences in panicles on leafy twigs in clusters of up to 30 spikelets on each internode and 1-8.5 cm apart. The spikelet is narrow ovoid, 13-22 mm long, 2-3 mm wide, has 2-3 empty glumas and 3 perfect florets.

Tali bamboo prefer hot and humid areas up to 1500 meters in disturbed forest, open areas and river banks on sandy or gravelly soils. The reeds become thin in dry places.

Bamboo slats were taken from 3 year old reeds and dried in air to a moisture content of 15.1% to obtain mechanical properties, for blades with and without internodes, respectively.

Specific gravity 0.50-0.67, fracture strength 87.5 N/mm2 and 74.9 N/mm2, parallel compression strength 37.5 N/mm2 and 33.9 N/mm2, shear strength 7.47 N/mm2 and 7.65 N/mm2, tensile strength 299 N/mm2.

The starch content of the reeds was 0.24-0.71% depending on the season. To reduce starch content and increase the durability of bamboo as a building material, it is usually soaked in water for 30 days and dried until it turns yellow and completely dry.

This bamboo is preferred for making various baskets and household wicker items, cooking utensils, fishing gear, furniture, musical instruments, ropes, and so on. Also used as poles, walls, floors, roofs, construction of various other buildings including bridges. Also fiberboard material.

The roots and reeds are used to treat diabetes and rejuvenate the skin. Root and reed extracts contain palmitic acid, stearic acid, oleic acid, curcumene, limonene, toluene, etc. Leaf extract has the property of inhibiting the activity of Escherichia coli.

Liverwort (Marchantia)

Liverwort ( Marchantia ) is a genus of plants in the Marchantiaceae, growing vines and attached to the soil surface, soft, dark green, upright phallus like a cup, grows in colonies on slopes and vertical soil that is moist and shady. Marchantia has elongated strands, rounded ends, branched, flat margins and a black vein in the middle. The strands formed a circular formation, growing widely and forming new formations around it. Sexual reproduction involves sperm from antheridia in male plants to fertilize ova in archegonia in female plants. The zygote develops into a small sporophyte which remains attached to the larger gametophyte. The sporophyte produces spores which develop into free-living male and female gametophytes. Asexual reproduction via gemmae in the cup-like structures on the upper surface of the plant. Asexual reproduction can also occur when older plant parts die and new, surviving branches develop into separate plants. Kingdom: Plantae Phylum: Marchantiophyta Class: ...

Wild durian (Cullenia exarillata)

Wild durian ( Cullenia exarillata ) is a species of plant in the Malvaceae, a tall tree with smooth, greyish-white bark, peeling on older trees, a straight trunk, horizontal branches and often with a series of knob-like tubercles for flower and fruit attachment. C. exarillata has young branches and the underside of the leaves is covered with golden brown peltate or shield-like scales. The leaves are single, alternate, glabrous, glossy green on the upper side and covered with silvery or orange peltate scales on the underside. Hermaphroditic flowers are tubular and also covered with golden brown scales, 4-5 cm long and cream or reddish brown in color. Flowers have no petals, formed of tubular bracteoles and tubular calyxes, 5-lobed. Fruit is round, 10-13 cm in diameter, covered with thorns and clustered along the branches. Many seeds, reddish brown, 4-5 cm long and 2-3 cm wide. The seeds are enclosed by a fleshy, whitish aril. The fruit splits open when ripe and dries to release the s...
