Elephant ear tree (Enterolobium cyclocarpum)

Sengon buto or elephant ear tree (Enterolobium cyclocarpum) is a species of plant in the Fabaceae, a medium to large tree, 25-35 m high, 3.5 m trunk diameter, umbrella-shaped crown, dry season sheds all leaves and circular pods.

E. cyclocarpum has a cylindrical stem, has many branches from a height of 2 meters, the bark is light gray with reddish brown vertical gaps. Old trees often show damaged, chipped or scarred bark.

Leaves compound bipinnate, 15-40 cm long, 17 cm wide, petiole 2-6 cm with 4-15 pairs of pinnae, each pinna with 40-70 leaflets. Leaflets are slender oblong, 8-15 mm long and 2-4 mm wide.

Globular inflorescences in the axils of new leaves, each head consisting of 50 individual flowers with thousands of thin, filamentous stamens. Each flower consists of 20 stamens and one pistil, very fragrant up to several meters in all directions.

The fruit has a diameter of 7-12 cm, dark brown, shiny, not broken, spiral-shaped like a round disc. The fruit is made of thick soft tissue, containing 8-20 seeds arranged radially. Seeds are 14.5-17.5 mm long, 7.8-11.2 mm wide, 6.2-7.2 mm thick, brown with light brown or orange rings and very hard.

Tolerant of various levels of rainfall, temperature and soil conditions. Most grow in the lowlands in tropical habitats. Widely used as an ornamental tree, shade, shade and create many oases in the hot plains and slopes. The wood is reddish brown in color, light and water resistant.

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...

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...

New living fossil, Amethyst worm lizard (Amphisbaena amethysta), from Espinhaço Mountain Range, Brazil

NEWS - New species from the northern Espinhaço Mountains, Caetité municipality, Bahia state, Brazil. Amethyst worm lizard ( Amphisbaena amethysta ) is the 71st species of the genus with 4 precloacal pores and the 22nd species of Caatinga morphoclimatic domain. Identification of the new species shows the reptiles of the Mountains are far from complete and may contain greater diversity of endemic taxa. A. amethysta can be distinguished by its anteriorly convex snout, slightly compressed and unkeeled, pectoral scales arranged in regular annuli, four precloacal pores, distinct head shield, 185-199 dorsal and half annuli, 13-16 caudal annuli, a conspicuous autotomy spot between the 4th-6th caudal annuli, 16-21 dorsal and ventral segments in the middle of the body, 3/3 supralabials, 3/3 infralabials and a smooth and rounded tail tip. A. amethysta occurs in areas with an average elevation of 1000 meters in patches of deciduous and semi-deciduous forests associated with valleys, slopes, fore...
