Pineapple (Ananas comosus)

Nanas or Pineapple (Ananas comosus) is a species of tropical plant in Bromeliaceae, low habitus and grows up to 1.5 m, annual herb, has about 30 or more leaves that are long, hard and waxy, spiny and sharp-pointed, arranged in a rosette and surrounding thick stem.

Pineapple fruit as sold by people is not a true fruit, but a combination of up to 200 true flowers that can be seen from every 'scales' on the skin which are combined together with cob (spadix) or compound interest into a large 'fruit'.

Dlium Pineapple (Ananas comosus)

Hummingbird is a natural pollinator for this plant, although various insects also have a similar role. The A. comosus cultivated by people has lost the ability to reproduce sexually, but they develop young plants using the 'crown' part of the fruit as a means of vegetative propagation.

Raw pineapple pulp is 86% water, 13% carbohydrates, 0.5% protein, and contains negligible fat (table). In a 100-gram reference amount, raw pineapple supplies 50 calories, and is a rich source of manganese (44% Daily Value, DV) and vitamin C (58% DV), but otherwise contains no micronutrients in significant amounts.

Nanas has traditionally been known to improve digestion and reduce acne. Fresh fruit is consumed directly or processed into a variety of delicious dishes. Long leaves are processed into fiber as a luxurious lace fabric.

Mashpi walkingstick (Trychopeplus mashpiensis) from Chocó, Ecuador, based on males, females and eggs

NEWS - Researchers report Mashpi walkingstick ( Trychopeplus mashpiensis Conle, Valero & Hennemann, sp. nov.) from the Chocó ecoregion of northwestern Ecuador is new to science based on its unique body ornamentation and egg structure morphology. Trychopeplus Shelford 1909 is a genus of Neotropical stick insects (Phasmida Leach 1815) known for its remarkable morphological adaptations that allow it to blend in almost perfectly with epiphytic lichens in its habitat. These adaptations make Trychopeplus one of the most cryptic stick insect genera. The genus was described to distinguish the Neotropical species from Pericentrus Redtenbacher 1908 based on morphological differences and distinct geographic distribution compared to the type species Pericentrus moewisi Redtenbacher 1908. Pericentrus is known to be restricted to East and South Asia, whereas Trychopeplus is endemic to the Neotropics.

Giant shield bug (Pycanum alternatum)

Giant shield bug or pycanum rubens ( Pycanum alternatum ) is a species of animal in Tessaratomidae, has a large shield covering the back, shiny green-blue-brown colored and appears to have a powder or wax layer, inhabiting the leaves of plants in open forests or bushes . P. alternatum is also called a stink bug because of its ability to release pungent aromas when disturbed. These insects live solitary with a partner and usually the mother gather in a family together in nymphs. White eggs are attached under the leaves of the plant. Nymphs can be found in the same host as their parent. The nymph has a flat rectangular shape with a large vein in the middle like a flat leaf. Nymphs having striking colors are light green, orange and red. Color may represent various stages of development or gender. The initial stage has a small size and red color. It grows in a bigger size and turns orange then ends in green. Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hemipter...

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 ...
