Dlium Petai (Parkia speciosa)

Dozens of long, flat pod-shaped fruits emerge from a flower hump hanging from a tree. Each pod has up to 10-20 seeds that are neatly arranged, 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.

Petai grows well in wet and slightly wet climates, low land to mountains with an altitude of 1,500 m, open spaces and lots of sun throughout the day with fine-tinted soil and Ph 5.5-6.5. Trees start bearing fruit after 4 years, fruit ripening 3-4 months and produce 4,000-5,000 pods per year.

Stink bean has at least two varieties. Petai Gajah has 25-30 cm long pods and 15-18 seeds, while Petai Kacang has 20 cm long pods and 10-12 seeds. Usually sold with pods included, but modern packaging is also done in airtight plastic or styrofoam.

Seeds are also added to a variety of vegetable soup or fried chilli mixed into cuts of beef or chicken. Nasi goreng petai kambing is a popular variant of fried rice with goat meat and petai.

Traditional medicine uses seeds to treat anemia, stress, premenstrual syndrome, depression, abdominal pain, intestinal worms and several other health problems. The cause of smelly petai seeds is amino acids that contain sulfur and produce H2S.

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...

Perlis fairy lantern (Thismia perlisensis) resembling Thismia arachnites Ridley and Thismia javanica J.J.Sm.

NEWS - Perlis fairy lantern ( Thismia perlisensis Besi & Rusea sp. nov.) was discovered during a scientific expedition in a wetland forest at the foot of a limestone hill, Perlis State Park, resembling Thismia arachnites Ridley (1905) and Thismia javanica J.J.Sm. (1910), but has a prominent reddish dome-shaped annulus. Thismia perlisensis can be easily distinguished from T. arachnites and T. javanica by its blood-red dome-shaped annulus (vs. ring-like with a rim, orange annulus), prominent trilobed stigma with bifid and subulate lobes 1.8 mm long (vs. oblong, truncated stigma), and claviform apex of inner tepal appendage (vs. subulate apex of inner tepal appendage). Stenoendemic to northern Peninsular Malaysia, Perlis State and possibly Langkawi Island. Although there have been sightings of the plant on Langkawi Island, this location is based solely on photos posted on social media. There are currently no specimens or additional information to confirm. The new species grows in...
