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.

Javan broadhead planarian (Bipalium javanum)

Cacing palu or Javan broadhead planarian ( Bipalium javanum ) is a species of animal in Geoplanidae, hermaphrodite, living on the ground, predators, often called only hammerhead or broadhead or shovel worms because of wide heads and simple copulatory organs. B. javanum has a slim stature, up to 20 cm long, up to 0.5 cm wide, head wide up to 1 cm or less, small neck, widening in the middle and the back end is rounded, all black and shiny. Javan broadhead planarians walk above ground level by raising their heads and actively looking left, right and looking up using strong neck muscles. Move swiftly, track meander, climb to get through all obstacles or make a new path if the obstacle is too high. Cacing palu track and prey on earthworms and mollusks. They use muscles and sticky secretions to attach themselves to prey to lock in. The head and ends of the body are wrapped around and continue to close the body to stop prey reactions. They produce tetrodotoxins which are very strong...

Swietenia mahagoni and Swietenia macrophylla, the differences

SPECIES HEAD TO HEAD - To date, mahogany ( Swietenia Jacq.) is recorded as having four species: West Indian mahogany or small-leaved mahogany ( Swietenia mahagoni (L.) Jacq.), big-leaf mahogany ( Swietenia macrophylla King), Honduran mahogany ( Swietenia humilis Zucc.) and Swietenia × aubrevilleana StehlĂ© & Cusin. The debate over the number of taxa in the genus is still not resolved. Some researchers believe that there are only two species: S. mahagoni and S. macrophylla . I agree with that opinion and the two species can only be differentiated by the size of the leaves. All species in this genus have similar morphology except for leaf size. The following is the key to identifying these two species. S. mahagoni has a stalk length of around 37 cm with 5-6 pairs of strands. The strands are about 10 cm long and about 3.5 cm wide. S. macrophylla has a stalk length of up to 45 cm with 4-5 pairs of strands. The strands are up to 31 cm long and up to 8 cm wide. By Aryo Bando...
