Compound inflorescence in bunches, long stalks, erect and gathered at the end of the stalk. There are more flowers at the bottom than at the top of the stalk so that they are in the shape of an elongated pyramid. Petals are bell-shaped and greenish-white.

The rhizome has a distinctive aroma, rough and spicy when it is old. The rhizome turns green, the fiber becomes hard and tough when dried. The taste is sharp, spicy, biting and smells good because of the essential oil content.

Galangal is a type of spice that is widely grown. Generally for a mixture of spices and traditional medicine. Utilization for cooking by beating the rhizome, then just dipping it into the cooking mixture, while for traditional medicine that is widely used is the red cultivar.

This species grows in open areas, in full sun or partial shade. Grows well in moist, loose soil. Grows poorly in flooded soils. It thrives in the lowlands to an elevation of 1200 meters. This plant grows wild in teak forests, pine forests or in shrubs.

The history of the cultivation and trading of spices originally took place on the island of Java. Galangal is still widely cultivated in Southeast Asia, especially in the Greater Sunda Islands and the Philippines. Cultivation has also spread to Southeast Asia, including Thailand.

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...
