Nodding clubmoss (Lycopodiella cernua)

Paku kawat or clubmoss or nodding clubmoss (Lycopodiella cernua) is plant species, terrestrial herbs with main stems creeping indefinitely, rooting at long intervals and at least 40 varieties have been described that are difficult to distinguish.

L. cernua has erect shoots and resembles small pine trees up to 100 cm tall, green and yellow, distal has many branches and arranged opposite, very compound with the ultimate whitish branch and nods down.

Dlium Nodding clubmoss (Lycopodiella cernua)

The leaves are arranged in a spiral, linearly circulated, 2-5 mm long, 0.1-0.3 mm wide, wide widened base, sharp pointed apices, overall margins, thick and stiff but soft, gradually changing from patent-reflexes and somewhat deep on the shoot axis to rise and approach the ultimate branches.

Conical structures that produce spore terminals on branches, sessile, ovoid to ellipsoid, 3-25 long and 1.5-5 mm wide. Sporophylls ovate become deltoid, 2x1 mm, rough and irregularly cut edges and yellowish or greenish.

Sporangium globose, opening with a valve that is very unequal and hidden by the sporophil base. Spores clot with a three-pronged scar and are slightly wrinkled. Nodding clubmoss produces spores throughout the year, but spends the dry season as the tip of the stem is buried while the rest of the plant dies.

The life cycle is somewhat different from true ferns because spores only germinate when covered in soil and total darkness. As they germinate, spores give rise to fleshy gametophytes that contain male and female sex organs.



Paku kawat grow on the edges of forests, secondary forests, margins of swamps, wet grasslands, moist cliff surfaces, hill slopes and mountain slopes to an altitude of 2400 m. Not found in areas with annual rainfall less than 600 mm.

This plant contains alkaloids such as cernuine and lycocernuine, flavonoids apigenin and apigenin-7-glucoside, triterpene serratenediol and aluminum concentrations up to 12.5%. Injections to mice are effective for silicosis. More research into pharmacological potential is needed, considering that many facts have been applied in traditional medicine in many places.

L. cernua applied to wound dressing, anti-lice, as a tonic, overcoming neuralgia, hypertension, ulcers, beriberi, cough and asthma, gum problems, abscesses, diuretics, gout, rheumatic swelling, skin irritation, gonorrhea, vaginal discharge, dysentery, hepatitis and burns.

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 ...

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 ...
