Tiger grass (Thysanolaena maxima)

Tiger grass (Thysanolaena maxima) is a species of plant in Poaceae, large and perennial grass, growing in dense clumps, morphology similar to bamboo but smaller in stems, the shoots have a white flour coating forming tiger-like stripes, flowers collected and used to make brooms.

T. maxima has an upright trunk and tends to be curved, up to 3 meters high, hard, has segments, has no branches and is dark green-black in color. The reed is solid, dense and not hollow. Ligules are membranous, 1-2 mm long and hairless.

The leaf blade is lanceolate-oblong and wide, stiff, up to 60 cm long, up to 10 cm wide, rounded base, sharp tip, a bone in the middle, the upper surface is dark green and rough, the lower surface is pale green and a horizontal mark forms mold in the middle.

The flowers are collected in large panicles at the end of the stem as terminals, 30-60 cm wide, 15-30 cm long. Each node has a branch, the wick has short hair, the bottom is free of spikelets, the lowest branch is up to 30 cm, the stalk is 2 mm. Single or paired spikelet and 1.5-1.8 mm. Kariopsis oblong and 0.5 mm.

Tiger grass grows in clusters or associations with clusters of trees or bamboo forests on hilly slopes, cliffs between rocks, bushes, forest edges, grasslands and riverbanks in tropical areas at an altitude of 1000 m.

Rumput awis is used to resist erosion and prevent landslides. It is planted for fences and ornamental plants. The young leaves are used as a mixture of animal feed and panicles are used in making brooms.

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...
