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.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Takenoshin Nakai swallow-wort (Vincetoxicum nakaianum) replaces V. magnificum and C. magnificum

NEWS - Researchers reported an erect herbaceous species distributed in the eastern part of Honshu Island, Vincetoxicum magnificum (Nakai) Kitag. based on Cynanchum magnificum Nakai, nomen nudum. Therefore, they named this species Takenoshin Nakai swallow-wort ( Vincetoxicum nakaianum K.Mochizuki & Ohi-Toma). Vincetoxicum Wolf (Asclepiadeae) is the third largest genus in the Asclepiadoideae consisting of about 260 species geographically extending from tropical Africa, Asia and Oceania to temperate regions of Eurasia. A total of 23 species are known from Japan, including 16 endemic species. Molecular phylogeny divides Japanese Vincetoxicum into four groups: the “Far Eastern” clade consisting of 11 endemic species and 4 more widespread species, 1 sister species to the “Far Eastern” clade, the “subtropical” clade consisting of 2 species and the “Vincetoxicum s. str.” clade consisting of 5 species. V. magnificum (Nakai) Kitag. (Japanese: tachi-gashiwa) is closely related to V. macro...
