Rain tree (Albizia saman)

Trembesi or Ki Hujan or monkey pod tree or rain tree or Samanea saman (Albizia saman) are species in Fabaceae, grow as large trees, tall, umbrella canopies and are very wide, flowering and bearing fruit, roots absorb a lot of water, popular as a shade and scattered throughout the tropics.

A. saman grows 30-40 m, stem diameter is 4.5 m and tree crowns can be 40-60 m wide. Tree trunks are sometimes bent, narrowed or bulging. The bark is grayish brown and smooth when young, but tanned, very rough and peeling when old.

The leaves are compound, pinnate bones, flat edges, elongated round shape, 2-6 cm long, 1-4 cm wide, dark green, slippery surface, the bottom has velvety, soft and 7-15 cm long stems. Light sensitive leaves that will close when it rains and at night where the tree is also called the "Tree at 5 pm".

White flowers and pink patches on the upper hair, up to 10 cm long from the base to the ends of the hair. Crown tube measuring 3.7 cm and 20-30 stamens which have a length of 3-5 cm. Nectar to attract insects to encourage pollination. Hundreds of flowers develop simultaneously filling the canopy.

Straight pods slightly curved, hard skin, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is blackish brown when ripe. Seeds number 5-25 items, length 1.3 cm, ellipsoid, flat, fat embedded in a reddish brown rag, very sticky and sweet.

The striking characteristic of a monkey pod tree is that branches form an umbrella that grows wider than height. A trembesi tree absorbs 28.5 tons of CO2 per year while other tree species only 1 ton of CO2 in 20 years. This tree also decreases gas concentration without greening and absorbs strong groundwater.



Rain tree grow quickly and are spread in the tropics with an average rainfall of 600-3000 mm / year, altitude 0-500 meters, various types of soil with a pH of 4.7 to 8.5 and able to survive 4 months without rain with a temperature of 20 -38C.

Tree trunks are used for building construction materials and leaves are extracted to treat skin diseases. Litter to reduce aluminum concentration, increase pH and absorb nitrogen content for the soil. Seeds are used as a laxative and are processed into nuts.

Ki Hujan Cultivation uses seeds soaked in water at 80C for 1-2 minutes and dried. Then immersed in water at a temperature of 30-40C for 24 hours to accelerate germination up to 90-100%. Sprouts ready for planting have a length of 20-30 cm.

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...

The ancestor of Homo floresiensis lived 700,000 years ago was smaller

NEWS - The remains of Homo floresiensis found by Australian-New Zealand archaeologist, Professor Mike Morwood (1950-2013) in Liang Bua cave, Flores, in 2003 gradually revealed its evolutionary origins. The very small adult leg bones belonging to the small-brained "Hobbit of Flores" are at least 700,000 years old. Previous archaeological evidence suggests that these tiny humans inhabited Liang Bua around 50,000 years ago, when Homo sapiens had long settled in southern Australia which ultimately gave rise to much debate about the origins of Flores humans. A hypothesis is that H. floresiensis is a hybrid of early Asian Homo erectus . Another hypothesis is the remains of a more ancient hominin from Africa before H. erectus and small-bodied from the start. If so, the likely candidates are Homo habilis or Australopithecus afarensis . Another hominin fossil ever found on Flores is the Mata Menge site 75 km to the east. The earlier site in the tropical grasslands of the So...
