Petai (Parkia speciosa)

Dlium Petai (Parkia speciosa)

Stink bean or bitter bean or pete or petai (Parkia speciosa) is a tropical tree species in Fabaceae, 5-25 m high and branched, reddish brown bark, always green, compound and pinnate leaves, young seeds are harvested as fresh or boiled food.

P. speciosa has a hump-shaped flower that hangs with a long stalk, usually appearing near the tips of the branches. Young flowers and not yet blooming are green, mature flowers have stamens and pistils, old flowers turn yellow and large in size.







Dozens of long, flat pod-shaped fruits emerge from a flower hump. Each pod has up to 10-20 seeds, green when young and wrapped in a rather thick membrane of light brown. The fruit dries and becomes harder as it ripens and releases the seeds.

This tree has at least two varieties. Petai Gajah has 15-18 seeds, while Petai Kacang has 10-12 seeds. Usually sold with pods included. Seeds have a distinctive and pungent odor, are consumed fresh or as a mixture of a number of dishes.

Bean is eaten raw with sambal as part of fresh vegetables, fried or roasted. Traditional medicine uses seeds to treat anemia, stress, premenstrual syndrome, depression, abdominal pain, intestinal worms and other.

This species grows at an elevation of 0-1500 meters, rainfall 1000-2000 mm/year, latosol to clay soil, pH 5.5-7, full sunlight and a wet climate.

The plants contain flavonoids, alkaloids, phenols, terpenoids (β-sitosterol, stigmasterol, lupeol, campesterol, squalene), cyclic polysulfides, thiazolidine-4- carboxylate, saponins, hexathionine, tetrathiane, trithiolane, penthathiopane, pentathiocane, tetrathiepane, djenkolic acid.

Often used to treat liver and kidneys, worms, stress, stomach ulcers, large warts, anemia, constipation, stop smoking, reduce high blood pressure and stroke, prevent morning sickness in pregnant women, has antioxidant and antidiabetic activity.

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis...
