The inflorescences are terminal bunches that hang and are 15-40 cm long. Fragrant flowers and 5 units of petals. The crown is 2-3.5 cm long and is bright yellow in color. The bottom three stamens are S-shaped and longer than the others.

The pods are cylindrical, 20-45 cm long, 1.5 cm wide, hanging, young dark green, dark black and cracked. The inside is divided by partitions into chambers containing 1 seed and each pod contains 25-100 seeds.

The seeds are flat and brown in color, transverse in space, separated by a bulkhead and a kind of sticky flesh and blackish brown in color.

Tengguli grows in tropical deciduous forests, is shade-tolerant, drought-resistant, tolerates rainfall of 480-2720 mm/year, annual temperature of 18-29C and soil pH of 5.5-8.7.





Kolobur is widely used for medicinal and ornamental trees. The pods, seeds, leaves, flowers and bark are used as a laxative, to clean wounds and ulcers, to clean skin fungus, to treat fever and diabetes.

The bark produces bright yellow tannins as a material for making horse shoes or clothing. Good quality wood, durable, strong, solid, heavy, hard, pale yellow to reddish in color and the inner wood is blackish gray. Wood has strong class II and durable class II.

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.
