Red eucalyptus (Eucalyptus pellita)

Red eucalyptus or red mahogany (Eucalyptus pellita) is a species of plant in the Myrtaceae, medium to tall tree, growing up to 40 meters tall cylindrical trunk, bark is rough or fibrous or flaky, dark red or grayish or brown in color.

E. pellita has green, glossy leaves on the upper side, broad lance-shaped to egg-shaped, 100-230 mm long, 30-65 mm wide and tapering to the stalk.

Flower buds are arranged in leaf axils on flat, unbranched stalks, 12-32 mm long and individual buds on stalks 6-7 mm long. Mature shoots are oval, 15-16 mm long and 9-10 mm wide with a conical or beaked operculum.

The fruit is woody, cup-shaped to capsule or conical, 6-11 mm long and 8-14 mm wide with the valve protruding strongly above the edge.

Red eucalyptus grows in open forests, especially on gentle slopes, in wet or dry areas, nearshore forests and lowlands.

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...
