Cornstalk dracena (Dracaena fragrans)

Drasena or cornstalk dracena (Dracaena fragrans) is a species of flowering plant in Asparagaceae, a shrub that grows slowly, is very adaptive and inhabits in altitude regions of 600-2250 m, multistemmed at the base, up to 15 m high or higher with narrow, upright and slender crowns.

D. fragrans has a round stem with a diameter of up to 30 cm, young plants have a single stem and are not branched with a rosette of leaves to the ends, producing two or more new stems with subsequent flowering episodes.

Lanceolate leaves, 20-150 cm long, 2-12 cm wide, green overall or yellow vertical stripes follow the bone trench in the middle for some varieties, shiny, upright young leaves to spread and larger leaves droop due to weight.

The flowers in panicles are 15-160 cm long, individual flowers have a diameter of 2.5 cm with a six-lobed corolla, are pink and open white with the center having a red or purple line on each lobe for 7-12 mm, very fragrant and popular with pollinating insects.

The berries are green and turn orange red when ripe, 1-2 cm in diameter and contain several seeds. Dracena cornstalk is used for ornamental plants and removes air pollutants including formaldehyde, xylene and toluene.

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...

Species-group Macrolycus ligulatus (Coleoptera, Lycidae) from China has five new species

NEWS - Researchers used macrophotography to describe the sex and aedea habits of net-winged beetles (Lycidae Waterhouse 1878) and reported five new taxa. Macrolycus ligulatus living in China has diversified into M. expansus , M. quartus , M. costus , M. opacipennis , and M. curtus . Yun Li, Ladislav Bocak and Hong Pang in 2015 divided the genus Macrolycus into nine species groups based on molecular phylogeny. The species groups are generally defined based on the shape of the apical part of the phallus and the shape of the attached structures. The M. ligulatus species group can be distinguished from the others by the phallus which is usually ventrodistrally widened, has a U- or V-shaped notch and a tongue-like lamella at the apex. However, some species do not fit this diagnosis very well. M. chapaensis and M. extrusus have a ventrally or dorsally widened phallic apical similar to most species of the M. murzini species group. Some species were originally included in the M. ligulat...

Sundanese gossamerwing (Euphaea variegata)

Sundanese gossamerwing ( Euphaea variegata ) is an animal species in the Euphaeidae, flying insects, dragonflies of medium size and large eyes, black wings with a diamond sheen, solitary life around water flowing in forests and shady farmlands. E. variegata has a black head with a pair of eyes on the left and right which are large, black and dominate the shape of the head. Black chest with faint yellow stripes. The hind stick is cylindrical, large, jointed, black, enlarged tip and ends with two spines. The legs are stick-shaped, have several joints, are black and have rows of spines. The wings are elongated with rounded tips, the veins move linearly and are black. The base of the wing is transparent.
