Elephant foot yam (Amorphophallus paeoniifolius)

Suweg or whitespot giant arum or elephant foot yam (Amorphophallus paeoniifolius) is a plant belonging to the genus Amorphophallus and is still closely related to bunga bangkai or titan arum (Amorphophallus titanum), walur or acung (Amorphophallus variabilis), konnyaku or Konjac (Amorphophallus konjac) and iles -iles or porang (Amorphophallus muelleri).

A. paeoniifolius produces edible stem tuber and has similarities in leaf morphology in the vegetative phase. The Suweg is annual but is considered to be bi-seasonal because the vegetative and generative phases do not appear together. The vegetative phase appears as leaves branching with soft stems.

Dlium Elephant foot yam (Amorphophallus paeoniifolius)

Elephant foot yams do not have a real stem, but tubers that are always below the surface of the ground. The stem tuber produces tuber buds from the side and gives rise to leaves which sometimes appear to be lumpy. Bulbs contain starch with a composition dominated by mannan, white and often have a tinge of pink or purple.

The main single leaf stalk is often considered a stem by the lay, growing upright, soft and colored with a white streak. The surface of the stem is rough and at a certain height becomes three secondary branches and will branch again as well as become stalks of leaflets. Leaves can coalesce on leaf stalks.

Flowers appear when energy deposits from flour in the tuber are sufficient for flowering. The entire leaf including the stalk will wither before the flower appears. The flowers are arranged in a compound in the typical structure of taro where the flowers grow on a cob protected by a flower sheath.

Flowers are not perfect, have one house and gather on the cob side with male flowers higher than female flowers. This generative structure at the time of bloom gives off the smell of carcasses that lure flies to help pollinate. Generative propagation by seeds or vegetatively with tuber seedlings.

God is tools

OPINION - God and spirit are controversial discussions in science and even mythology will have no place among naturalists and for Darwinians. Apparently this has been final that mythology is a delusional, mystical and superstitious concept that cannot be empirically proven in the world of science.

Most scientists and science activists have agreed that god is nonsense, delusional and cannot be accommodated in the theory of evolution. This opinion can be understood methodologically and I agree with the sentences. But so many behaviors are very real and occur in the field.

I am a fieldman who goes to the wild every day, along rice fields and forests to watch insects to plants, talk to people especially in villages, visit Hindu-Buddhist temples built in the 8th century, witnessing busyness in mosques, temples and churches.

I feel something is missing in the view of naturalists and Darwinians. There are short moments that are missed in analyzes in the timeline of human evolution. These lit…

Porang (Amorphophallus muelleri)

Porang or iles-iles (Amorphophallus muelleri) is a plant species in Araceae, the leaves are pseudo stems with a height of 40-180 cm and a diameter of 1-5 cm, tubular, green with irregular white patches, each branching point grows bulbil colored brown and yellow tubers.

A. muelleri has pseudo stems and leaves that are bright green to dark green and have greenish white patches. The surface of the stalk is smooth, while the leaves are smooth wavy. Ellipse-shaped leaves with pointed tips.

When flushing has 3, 4-5, 5-6 and finally 6 minor leaf strands with 3 small leaf stems. Young leaves have edges that are light purple, green and will end yellow with a width of 0.3-0.5 mm. Canopy has a width of 50-150 cm.

Stems grow on tubers with a diameter of 25-50 mm and height 75-175 cm. The color of the tuber is brownish or beige on the outer surface and brownish on the inside, rather oval and stringy roots, weight 450-3350 grams, fine tissue, 4-5 months dormant period and 35-55% glucomannan content.

Javanese grasshopper (Valanga nigricornis)

Wooden grasshoppers or wooden walang or Javanese grasshopper (Valanga nigricornis) are grasshopper species in Acrididae and have around 18 subspecies, most of which are endemic to various island groups in Indonesia. This insect has a very broad sexual dimorphism where males have a length of 45-55 millimeters and females 15-75 mm.

V. nigricornis is yellowish brown or yellowish or green with bluish black marks. The back wing is rose red when flying. The nymphs are pale green and dark. They live in forests, bushes and really like the leaves of the giant sensitive plant (Mimosa diplotricha) and giant sensitive tree (Mimosa pigra).

Javanese grasshopper has one generation every year where four eggs are placed on moist soil in forest clearing. The eggs are not active throughout the dry season and it takes six to eight months to hatch.

The eggs hatch into nymphs and pass seven instar stages before becoming winged adults. Wood grasshoppers are solitary insects and do not form flocks, but outbre…
