Golden leather fern (Acrostichum aureum)

Dlium Golden leather fern (Acrostichum aureum)

Golden leather fern (Acrostichum aureum) is a species of plant in the Pteridaceae, an upright shrub, grows in large clumps and forms round plots, 2 meters high, stems short and stocky, fibrous, covered with large scales and brownish or pale in color with a black center line.

A. aureum has compound, pinnate, leather-like leaves and is up to 3 meters long. The minor leaves are narrow oval to elliptical, blunt or rounded at the base, blunt at the tip, mucronate, 24-30 pairs, irregularly seated and sometimes loose, dark green, erect or curved.



Several pairs (5 pairs or more) of minor leaves at the tip are often fertile and rusty or brownish in color, with the underside covered by many large sporangia. Sterile leaves sit on the bottom, are longer, have blunt or rounded tips and a short, small tip protrusion.

This species grows in tropical and subtropical areas, damp lowlands, coastal areas, open mudflats, brackish swamps, mangrove forests, tidal streams and grows well in full sun.

Plants contain beta-sitosterol, alkaloids, flavonoids, phenolics, catechins, saponins, tannins, glycosides, terpenoids, steroids, amygdalin, arbutin, formic acid, oxalic acid, five phytosterols (stigmasterol, y-sitosterol, campesterol, cycloartanol, and 24- methylene cycloartanol), 2 sesquiterpenes ((2R,3S)-sulfated pterosin C, (2S,3S)-sulfated pterosin C), as well as 2 derivatives ((2S,3S)-pterosin C and (2R)-pterosin P).

Often used to treat poultices for wounds and boils, snake bites, syphilis ulcers, sore throats, chest pain, elephantiasis, constipation, diabetes, cloudy urine in women, fever reducers, worm medicine, stops bleeding and is an emollient.

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...

Awar-awar or lagnob or hauli tree or barabar or sirih popar or tobo tobo ( Ficus septica ) is species of plants in Moraceae, trees grow in bushes or in neglected places and sap contained in roots, twigs, leaves and fruit is used to treat poisoning and digestive problems.
