V. velutina has a velvety brown or black chest with a brown belly. Each ventral segment has a narrow yellow border except for the fourth segment which is orange, black head and yellow face but varies widely in color and several subspecies have been identified by geographic coverage.

The female has a stinger to defend the nest and kill prey. Large egg-shaped nests up to 50 cm in length. The nesting season is long and the colony usually starts with building a nest in low bush, then leaves after a few months and quickly builds a new nest in the tree.

Giant green leech (Raksasa hijau)

Lintah raksasa or giant green leech ( Raksasa hijau ) is a species of animal in Salifidae, large green leeches, carnivores, not hematophagic, can grow to lengths of more than 50 cm, the front is perfectly tubular, but it is getting bigger, wider and flat backward. R. hijau has a front end that ends with a white mouth and has a width equal to the diameter of the front end of the body. The rear end ends with the anus and has a width equal to the diameter of the rear end of the body. The upper surface is whole dark green or leafy green, looks shiny and has no other additional color features. The bottom surface is lighter or brownish green. The skin is wrinkled like tight, elastic joints that make it possible to lengthen the body. Giant green leech moves forward by extending the tip of the front of the body to keep the new location farther away and this movement is then followed by the middle body and gradually the rear where the body moves completely. R. hijau does not suck blo...

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 ...
