Palmgrass (Setaria palmifolia)

Palmgrass (Setaria palmifolia) is a plant species in Poaceae, a perennial grass with broad and leathery leaves, green, hairy, grows wild in the shade, is widely cultivated as an ornamental plant, some cultivars have striped leaves and purple midribs, stems are eaten after cooking

S. palmifolia has a trunk that grows to 2-3 meters from a complex rhizome, 1 cm thick and hairy. Leaves are rarely completely hairy, blades linear, oval or lance-shaped, 60-80 cm long and 7-8 cm wide. Pointed tip, a bone in the middle, pleated texture and coarse or hairless hair.

The grain in panicles, yellowish green in color, opens and spreads, up to 80 cm long. Spikelets are several millimeters long but are often accompanied by hairs up to 1.5 cm long.

The grass is strong and spreads through rhizomes and seeds, forming monotypic stands. The broad leaves shade other vegetation. Cultivated as an ornamental plant for palm-like pleated leaves. It is also grown as a vegetable for stalks and grains are eaten as a substitute for rice.

Laniger bat tick (Ixodes lanigeri), new hard tick species (Ixodidae) from mouse-eared bats (Myotis) in Vietnam

NEWS - Researchers have identified Ixodes ticks from Vietnam based on morphological and molecular characteristics of females, nymphs and larvae as a new species, laniger bat tick ( Ixodes lanigeri ), which like other members of the Ixodes ariadnae complex appears to show a preference for vesper bats as a typical host. Historically, for more than a century and a half, only one species has been called the “long-legged bat tick”: Ixodes vespertilionis Koch. However, over the past decade, it has been molecularly recognized that long-legged ixodid ticks associated with bats may represent at least six species. Host associations and geographic separation may explain the evolutionary divergence of the new species from its closest living relative Murina hilgendorfi Peters in East Asia, Japan, as no Myotis or Murina spp. have overlapping distributions between Vietnam and the Japanese mainland. On the other hand, assuming that I. lanigeri may be present in other myotine bats and knowing that s...

Kemlanding or giant golden orbweaver ( Nephila pilipes ) is an animal species in the Araneidae, a web spider with a vertical and asymmetrical mesh, sexually dimorphic with elongated females up to 20 cm in size and has a large investment in egg production and web construction, whereas males only a few millimeters. N. pilipes displays female gigantism and male dwarfism. Females usually have a body size of 30-50 mm, the cephalothorax is 15 mm long and 10 mm wide. The stomach is 30 mm long, 15 mm wide and is mostly tawny with yellow stripes. The female has black or brown, covered in thick hairs. The two rows of eyes stick out towards the back. Plastron is mostly black and brown. The legs are very long, stick-shaped with several joints, black and yellow, lacking of hairs.
