Keji beling (Strobilanthes crispa)

Keji beling (Strobilanthes crispa) is a species of plant in the Acanthaceae, shrub, 1-2 meters high, upright, woody and sturdy, stems are jointed, cylindrical in shape, coarse hairs, green in color, branches touch the ground and come out of the roots so they can be separated from the plant parent, single root and light brown in color.

S. crispa has leaves with stalks and sits opposite each other. The strands are lanceolate, elongated or almost oblong, 17 cm long, 7 cm wide, serrated edges, tapered tip and base and rough surfaces on both sides. The veins are pinnate and green.

The inflorescences are compound and gathered in dense spikelets. The crown is funnel-shaped, 5 parts, hairy and yellow or purple in color. Stamens 4 items, white and yellow. Spindle-shaped fruit with 2-4 seeds. The seeds are round, flat, small, and brown.

This species grows in forests, riverbanks, cliffs and roadsides at elevations of 50-1200 meters, rainfall of 2500-4000 mm/year, sandy to clay soil and a pH of 5.5-7. This plant reproduces easily in fertile soil, somewhat protected and open places.

This plant contains alkaloids, tannins, saponins, flavonoids, polyphenols (tocopherol, cinnamic acid, phosphatide), catechins, caffeine, silicic acid, kersic acid. This plant is used as an anti-diabetic, diuretic, anti-syphilis, antioxidant, antimicrobial and laxative, dysentery, diarrhea, kidney stones, fever, lowering cholesterol, hemorrhoids, poisonous snake bites, urine laxative, leukemia and preventing AIDS.

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 Stehlé & 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...
