Elephant ear (Xanthosoma robustum)

Elephant ear (Xanthosoma robustum) is a species of plant in the Araceae, 0.4-1.5 m tall, stemless and not woody, has 2-5 leaves with stems of plain green or purplish stripes, flowers in the middle and grow to form a colony

X. robustum has ovate or oblong leaves with tapered or rounded tips, green and shiny upper side, sometimes purplish around the stem, bright green or pale underside.

Flowers come in cobs in the axils of leaves and have stalks. The sheath is green or yellow or white and falls off.

Leaves, stems and tubers are used as animal feed and carp. Shield-shaped and wide leaves are often used as head protection when it rains, food wrappers and live fish containers.

Tekijem (Cyperus cyperoides)

Tekijem ( Cyperus cyperoides ) is a plant species in Cyperaceae, annual grasses that grow in seasonal wetlands, open or shaded fields, swamps, ponds, rice fields, roadsides, open forests, secondary forests and shrubs at altitudes up to 1,800 m in the tropics. C. cyperoides has an upright, triangular shape, 20-75 cm tall from a very short rhizome and has no stolon. The lanceolate-shaped leaves are narrow and long, the tips are pointed, slippery, shiny, green and grow at the bottom and at the top of the stem. The terminal flower appears on the tip of the stem, cylindrical spiklet shaped and green. Each stem has two to seven flowers, each of which has a short or long stem that grows at the end of the stem together with the leaves. Tekijem grows solitary or in small groups at a distance. Propagating using vegetative and generative methods using seeds. At least three sub-species are Cyperus cyperoides cyperoides , Cyperus cyperoides flavus and Cyperus cyperoides pseudoflavus . Th...

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...

Kemadih ( Schultesianthus coriaceus ) is a species of plant in the Solanaceae family. It grows as a climber and covers host trees. It is a perennial, multi-branched, hardwood plant with hard, brown bark and dark green young bark. S. coriaceus has thick leaves, 15 cm long and 8 cm wide. A central vein is linear, with a pointed tip and base. The upper surface is dark green and the lower surface is bright green. The petiole is 3 cm long. The flowers are fan-shaped with 5 inflorescences. The base is narrow, whitish-yellow or bright green, and 8 cm wide. Four inflorescences with brownish-white tips and one inflorescence with a green tip grow in the center. The fruit is green, 3.5 cm long, and the stalk is 2 cm long.
