Songotan (Pogostemon auricularius)

Songotan (Pogostemon auricularius) is a species of plant in Lamiaceae, a perennial shrub that grows upright, 30-80 cm high, simple or loose branched stems, weak, blunt 4 corners, hair spread, pink, has strong bolts and grows wild in the forest, tidal areas and roadsides.

P. auricularius has leaves oval or elliptical or ovoid, 4-6 cm long, 2-3 cm wide, cuneate base, pointed tip, serrated edges that are irregular except near the base, hairy, a bone in the middle and several veins that is pinnate. The petiole is 2-10 mm long and hairy.

Dlium Songotan (Pogostemon auricularius)


The inflorescences consist of dense verticillasters, forming dense terminal spikes and 4-10 cm long. Narrow elliptical bracts and long ciliates. Subcampanulation petals, dotted outer glandular, 1.2-1.5 mm long, has 5 unequal teeth, triangles and cilia.

The petals are urn-shaped, 2.5-3.5 mm long and teeth often appear above the shoots. The crown has a size of 2-3.5 mm, a slender, protruding tube, 4 lobes, equal, blunt, pubescent and pale pink or white in color. Stamens 4 strands, subequal, filament length 3.5-4 mm, slender, upper half villi and purple.

The fruit consists of ellipsoid bean-shaped seeds, 0.6 mm long, 0.4 mm wide, smooth reticulate and brown in color. The seeds germinate epigeal, hypocotyl 1-2 mm and glandular. Triangular cotyledons, 2 mm long and blunt apex. Epicotyl hair and greenish to purplish in color.

Shoots have the first 2 leaves, ovate, 3.5 mm long, crenate edges, prominent nerves, hairy and glandular at the bottom. Songotan grows in sunny areas, bordered by ditches, dams and rice fields in grassy desert and scrub at altitudes up to 2000 m.



Songotan is used to treat simple stomach problems in children, flatulence, diarrhea, intestinal worms, mouth sores, kidney problems, sore throat, malaria, rheumatism, diuretics or antipyretics, anti-carcinogens and menstrual pain. The leaves are also used as an insecticide for stored cereals.

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...

Purhepecha oak (Quercus purhepecha), new species of shrub oak endemic to the state of Michoacán, Mexico

NEWS - In Mexico, several Quercus shrubby species are taxonomically very problematic including 8 taxa with similar characteristics. Now researchers report the purhepecha oak ( Quercus purhepecha De Luna-Bonilla, S. Valencia & Coombes sp. nov.) as a new tomentose shrubby white oak species with a distribution only in the Cuitzeo basin in the Trans-Mexican Volcanic Belt (TMVB). Quercus Linnaeus (1753) subdivided into 2 subgenera and 8 sections of which section Quercus (white oaks) has the widest distribution in the Americas, Asia and Europe. This section is very diverse in Mexico and Central America with phylogenomic evidence indicating recent and accelerated speciation in these regions. The number of shrubby oak species in Mexico is still uncertain. De Luna-Bonilla of the Universidad Nacional Autónoma de México and colleagues found at least 3 taxa in the TMVB, specifically Quercus frutex Trelease (1924), Quercus microphylla Née (1801) and Quercus repanda Bonpland (1809). In 2016,...

Pundak scoliid (Scolia clypeata)

Pundak scoliid ( Scolia clypeata ) is an animal species in Scoliidae, arboreal insects, elongated body, blackish blue wings, round head, long legs, spending time perched on leaves in the shade in the bush, medium-sized trees in the forest and agricultural land. S. clypeata has a round, red head and a pair of large black eyes on the face. A pair of large antennae, red, jointed, black base and blunt tip. The neck is narrow and black. The back is dark brown and rough. The front shoulders on the right and left sides have a red plot color. The stomach is cylindrical, elongated, with long hair, droplet-shaped tips and shiny black color. A pair of elongated wings with multiple veins, rounded tips, blackish blue and shiny, piled together to cover the entire abdomen at rest. The legs are several joints and have long hair. Pundak scoliid live in forests or agricultural fields, spending much of their time perched on leaves in low shrubs or medium-sized trees, in shade and more solitary. King...
