The leaves are egg-shaped or oblong, 2-9 cm long, 1.5-5 cm wide, the upper side is glabrous and shiny, the lower side has whitish hair, the three main veins are clearly visible running parallel. Leaf stalks are 8-15 mm long.

The inflorescences are umbrella-shaped, forked, growing in the leaf axils, 1-2 cm long and have 7-20 flowers. The flowers are 2-3 mm in diameter, yellowish, slightly fragrant and peduncles 3-8 mm long. The petals have 5 spurs and are triangular in shape. The flowers have 5 petals, somewhat spatula-like, concave and curved.



Fruits are round to ovoid, up to 6 cm but mostly much smaller, skin shiny and thin but strong, yellowish or reddish to black when ripe. White flesh with lots of juice and a sour to sweet taste. The seeds are protected in a shell and have irregular grooves, are brown and oval-shaped.

Fruit is bought and sold as fresh fruit to be eaten directly or made into fresh drinks. The fruit is also dried or candied. Young fruits are eaten with salt. Fruit is a source of carotene, vitamins A and C.

The young leaves are used as vegetables and the old leaves are used as animal feed. A decoction of the leaves is drunk as a herbal medicine. The leaves foam like soap when kneaded in water and are used to bathe people with fever. The leaves are also used to bathe corpses.

Good quality firewood with calories of 4,900 kcal/kg. Bark and bidara fruit are also used as dyes. These materials produce tannins and a reddish-brown or grayish coloring.

This species grows in areas with clear dry seasons, hot and rich in sun, but also experiences adequate rainy seasons to grow twigs, leaves and flowers, and maintain soil moisture during fruit production. Grows with rainfall of 300-500 mm/year and elevations of up to 1000 meters.

This tree is easy to adapt and often grows wild on land that is poorly maintained and on the side of the road. Grows in various types of soil including laterite, well-drained black soil, sandy soil, clay, alluvial soil along river flows.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Javan mocca or Javan slender caesar (Amanita javanica)

OPINION - Javan mocca or Javan slender caesar ( Amanita javanica ) is a mysterious fungus species and has been enigmatic since it was first reported by Boedijn in 1951 and after that no explanation or reporting of specimens is believed to be the same as expected. Boedijn (1951) described A. javanica which grew on Java island as having the characteristics covered in the Amanita genus. Corner and Bas in 1962 tried to describe Javan mocca and all species in Amanita based on specimens in Singapore. Over time some reports say that they have found A. javanica specimens in other Southeast Asia including also China, Japan, India and Nepal. But there is no definitive knowledge and many doubt whether the specimen is the same as described by Boedijn (1951). I was fortunate to have seen this species one afternoon and soon I took out a camera for some shots. In fact, I've only met this mushroom species once. Javan mocca is an endangered species and I have never seen in my experience in...
