Broad-leaved paperbark (Melaleuca quinquenervia)

Kayu putih buku or broad-leaved paperbark (Melaleuca quinquenervia) are small to medium sized trees in Myrtaceae, up to 20 m high, stems covered by thin white, cream, and gray paper skin. The leaves are arranged, flat, rough, spear-shaped, dull or green-gray, 55–120 mm long and 10–31 mm wide.

The flowers are packed in strands at the end of the branch and continue to grow after flowering, sometimes also in the upper leaf axils. Each strand contains 5 to 18 flower groups, diameters up to 40 mm and lengths of 20-50 mm. The petals are about 3 mm long and fall out when the flowers age.

Flowers are followed by woody fruits, shaped cylindrical capsules wide, 2.5-4 mm long and in groups. Each capsule contains many small seeds that appear every year. M. quinquenervia has proven to be a different chemical form and is widely used traditionally. Drinks are made from young aromatic leaves to treat colds, headaches, and common ailments.

Leaf oil from chemotype cineole is used externally for coughs, colds, neuralgia, and rheumatism. Nerolidol and linalool chemotypes are also cultivated and distilled on a small scale for fragrances. Bark like paper is used traditionally to make coolamons, shelter and wrap baked goods.



Nectar is traditionally extracted by washing in water and consumed as a drink. Scented flowers also produce yellow honey, very flavorful although not considered a high-quality honey but popular. Essential oils for various cosmetic products, antiseptic and antibacterial agents for bladder infections, respiratory problems and inflammation of the nasal mucous membranes.

Green vestment mantis (Phyllothelys qingjinum) from Malipo, Yunnan, with cross collar on pronotum

NEWS - Green vestment mantis ( Phyllothelys qingjinum ) from Malipo, Yunnan, China, is described based on geometric morphometric, genetic distance and molecular phylogenetic analyses. The discovery of this new species fills a significant distribution gap for the P. werneri group in southern Yunnan and highlights the need for further exploration in this region. Phyllothelys Wood-Mason, 1876 (Mantodea, Hymenopodidae) includes 22 species with China being the hotspot containing 15 species in four groups, especially P. werneri which includes 6 species. This suggests a wide distribution across the mountainous region south of the Yangtze River extending from Medog in the west to Taiwan Island in the east. P. qingjinum has dimensions (mm) with head to abdomen: 52.75-54.95, head to wing: 58.60-62.14, pronotum: 15.30-17.76, prozone: 3.46-3.95, metazone: 11.84-13.88, anterior coxa: 8.39-10.64, anterior femur: 9.36-11.46, anterior tibia: 5.55-7.02, posterior femur: 7.82-9.35, posterior tibia: 6....

Shovelbill shark (Sphyrna alleni), hammerhead shark (Sphyrnidae) from Caribbean and Southwest Atlantic

NEWS - Researchers have identified a new species of hammerhead shark as the shovelbill shark or Requin-marteau pelle or Tiburón Cabeza de Pala ( Sphyrna alleni ) collected at Robinson Point and Riversdale Village, Belize, and provided by local fishermen in 2016 and 2019. S. alleni is named after Paul G. Allen (1953-2018), a philanthropist who supported shark research and conservation. Shovelbill shark is max 150 cm long when mature with a flat, shovel-shaped head that lacks a notch on the anterior margin, a pointed (triangular) cephalofoil in both sexes and a distinct protrusion in males. The posterior margin is lobulated. The posterior teeth are enlarged, molar-like, the first dorsal tip is anterior to the pelvic origin and the posterior margin of the anus is shallowly concave. It differs from S. tiburo in that the anterior margin of the head is more rounded and the posterior margin lacks lobules. The number of precaudal vertebrae for S. alleni is between 80-83 (~10 more vertebrae ...
