Giant reed (Arundo donax)

Glagah putih or giant reed (Arundo donax) is a species of plant in the Poaceae, tall perennial reeds, long erect reeds, hard and woody, hollow, growing to form dense colonies in moist, riparian, freshwater and saltwater habitats.

A. donax grows to a height of 6-10 meters and a stem diameter of 2-3 cm. The leaves are elongated, gray or green or white, alternate, 30-60 cm long, 2-6 cm wide, pointed at the tip and have a tuft of hairs at the base.

Flowers have erect feathers, 40-60 cm long and have seeds or without seeds. Most reproduce vegetatively with hard and fibrous underground rhizomes, spreading and penetrating up to 1 meter into the soil.

Giant reed adapts to a variety of ecologies from heavy clay to loose sand and gravel soil, contaminated with arsenic, cadmium and lead. The species has two varieties, Arundo donax var. donax and Arundo donax var. versicolor.

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...
