African tulip tree grows naturally in secondary forest, high forest zone, deciduous transition forest, savanna forest and wet areas. This species rehabilitates degraded land through rapid growth. Creamy white, soft and light wood for carpentry, crates and covers. Edible seeds and plant extracts are used in medicine.

Ampoule-shaped flower buds and contain water, the buds are often used by children who play with their ability to spray water. The sap sometimes turns yellow on the fingers and on clothes. The open, cup-shaped, rain and dew resistant flowers are attractive to many bird species.

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 ...
