Arrowleaf elephant's ear (Xanthosoma sagittifolium)

Arrowleaf elephant's ear (Xanthosoma sagittifolium) is a plant species in Araceae, 0.4 to 1.5 m high, has no stem and is not woody, waxy leaves, important tuber producers where corm that grows underground is a source of carbohydrates and cultivated since ancient times.

X. sagittifolium has 2-5 leaves with green stems, dark green or purplish stripes, 23-150 cm long and the base is a midrib. Leaves have a size of 6.60x7.53 cm, round eggs, oval with tapered ends, sometimes purplish in color around the stalks, waxy and rounded base.

The flower comes in the cob on the armpit of the leaf. The sheath has a green or yellow or white and fall out. Arrowleaf elephant's ear is grown for tubers as an important source of carbohydrates. Tubers can be processed by steaming, boiling, baking, frying, or processed into flour, porridge, cakes, pasta and fermented to produce pudding.

Molucca albizia (Falcataria moluccana)

Sengon laut or Molucca albizia ( Falcataria moluccana ) is a species of wood-producing trees in Fabaceae, claimed to have the fastest growth in the world with the addition of a height of 7 m/year, producing white light wood for light construction, packing crates, particle boards and blockboards. F. moluccana has a height of 40 m and a diameter of 100 cm or more, the main stem is generally straight and cylindrical with clear bole up to 20 m. The bark is gray or whitish, smooth or slightly warted with a line of lenticels. Shady canopy, umbrella-shaped and tenuous. Young twigs have sides and hair. Double pinnate compound leaves, small minor leaves, easily fall out with one or more glands on the stem and length 23-30 cm. Leaf fins number 6-20 pairs, each containing 6-26 pairs of elliptical or elongated minor leaves with a very tilted, pointed tip, 0.6-1.8x0.5 cm. Small flowers, yellowish white, hairy, androgynous, collected in branched panicles, 10-25 cm long and located in the arm...

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

Banded dragonfish (Akarotaxis gouldae) diverged from Akarotaxis nudiceps 780,000 years ago

NEWS - A new species of dragonfish, Akarotaxis gouldae or banded dragonfish, off the western Antarctic Peninsula by researchers at the Virginia Institute of Marine Science at Gloucester Point, the University of Oregon at Eugene, and the University of Illinois at Urbana-Champaign, highlights the unknown biodiversity and fragile ecosystems of the Antarctic. A. gouldae was named in honor of the Antarctic Research and Supply Vessel (ARSV) Laurence M. Gould and crew. The larval specimen was collected while trawling for zooplankton and was initially thought to be the closely related Akarotaxis nudiceps hundreds of thousands of years ago. DNA comparisons with A. nudiceps specimens held in collections at the Virginia Institute of Marine Science, Yale University, and the Muséum national d’Histoire naturelle in Paris showed significant variation in mitochondrial genes that suggested the larval sample was a distinct species. Andrew Corso of the Virginia Institute of Marine Science and colle...
