Broom grass (Thysanolaena latifolia)

Rumput sapu or broom grass (Thysanolaena latifolia) is a species of plant in Poaceae, grows perennial in clumps, upright stems and curves downward to lie down in the center, is green, grows on slopes, flowers in panicles are collected and used to make brooms.

T. latifolia lives chronically in clumps, stems erect, 200-400 cm high, hard, unbranched and curved. A solid and strong reed was not hollow. The ligula is a hairless membrane, 1-2 mm long and rompang.

The leaves are elongated, lanceolate-oblong like hides, sharp edges, stiff and crispy, 30-60 cm long, 3-7 cm wide, green, clearly visible cross-veins and a transverse stamp print in the middle

The flowers are collected in large, open panicles at the tips of the stems, oval or ovate, 30-60 cm long and 15-30 cm wide. The main branches in each node, the axis has short hair, the lower part is free of spikelets, the lowest branches are up to 30 cm and the stalk is 2 mm. Single or paired spikelet and 1.5-1.8 mm. Kariopsis oblong and 0.5 mm.

Broom grass grows in semi-open areas, clustered or associated with clusters of trees or bamboo forests on hilly slopes, cliffs and furrows, between rocks, shrubs, forest edges, grasslands, river banks at an altitude of 300-2000 meters.

Rumput sapu is deliberately planted on steep slopes to prevent erosion and landslides. The young leaves are used as a mixture of animal feed, panicles are used in the manufacture of brooms and are often grown as ornamental plants.

Guinea grass (Panicum maximum)

Guinea grass or buffalo grass or green panic ( Panicum maximum ) is a plant species in Poaceae, annual grasses, growing upright to form clumps, strong, cultivated in all tropical and subtropical regions for very high value as fodder. P. maximum reproduces in very large pols, fibrous roots penetrate into the soil, upright stems, green, 1-1.5 m tall and have smooth cavities for diameters up to 2.5 mm. Propagation is done vegetatively and generatively. Ribbon-shaped leaves with a pointed tip, very many, built in lines, green, 40-105 cm long, 10-30 mm wide, erect, branched, a white linear bone, often covered with a layer of white wax, rough surface by hair short, dense and spread. The flower grows at the end of a long and upright stalk, open with the main axis length to more than 25 cm and the length of the bunches down to 20 cm. Grains have a size of 3x4 mm and oval. Seeds have a length of 2.25-2.50 mm and each 1 kg contains 1.2 - 1.5 million seeds. Guinea grass has two varieties. P...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
