Redflower ragleaf (Crassocephalum crepidioides)

Sintrong or ebolo or thickhead or redflower ragleaf (Crassocephalum crepidioides) are plant species in Asteraceae, terma height 25-100 cm, white fibrous roots, generally grow wild on the roadside, yard gardens or abandoned lands at altitude 200- 2500 m.

C. crepidioides has erect or horizontal stems along the soil surface, vascular, soft, non-woody, shallow grooves, green, rough surface and short white hair, aromatic fragrance when squeezed. Petiole is spread on stems, tubular and eared.

Dlium Redflower ragleaf (Crassocephalum crepidioides)

Single leaf, spread out, green, 8-20 cm long, 3-6 cm wide, longitudinal or round inverted eggshell with a narrow base along the stalk. Pointed tip, flat-edged or curved to pinnate, jagged rough and pointed. The top leaves are smaller and often sit.

Compound flowers grow throughout the year in humps that are arranged in terminal flat panicles and androgynous. Green cuffs with orange-brown to brick-red tips, cylindrical for 13-16 mm long and 5-6 mm wide.

The crown is yellow with a brownish red tip and has five steps. The anthers and pistils are purple and the petals close together. The blooms will be tubular, green and nod down but erect after becoming a fruit.

The fruit is hard, slender elongated, has 10 ribs, 2.5 mm long with many fine brush hairs and is white to 9-12 mm long. The seeds spread by riding in the wind and traveling long distances.



Redflower ragleaf is often found in fertile wastelands, river banks, roadsides, tea and quinine plantations, especially in damp areas. Also in the dry fields. This plant is identified as a bi-season weed that is easily overcome.

Sintrong is thought to contain pyrolizidine alkaloids which can trigger tumors, but traditional societies utilize them as vegetables and animal feed. Some parts of the plant are used to treat stomach disorders, headaches, wounds, hemostasis, tonic, laxatives, fever, tonsillitis and eczema.

Korean mulberry (Morus indica)

Murbei or Korean mulberry ( Morus indica ) is a species of plant in Moraceae, shrub or small tree, up to 10 meters tall, slow growing, cylindrical stem, light brown with white nodules, M. indica has heart-shaped or oval-shaped leaves and sometimes three-lobed, 4-12.5 cm long, 2.5-7.5 cm wide, pointed tip, serrated margin, green and has a stalk. Monoecious inflorescences with male and female grow on the same tree, though often on different branches. Male flowers have a size of 9-11.5 mm and are covered with fine hairs. The female flowers are subglubose or only round in shape, measuring 6-9.5 mm. Stigma is 3.5 mm long with short, thick hair. The female flowers form compound fruit and are fleshy, green and white-haired to white, red and black when ripe. Korean mulberry is used in regulating blood glucose levels in diabetic patients.

Swietenia mahagoni and Swietenia macrophylla, the differences

SPECIES HEAD TO HEAD - To date, mahogany ( Swietenia Jacq.) is recorded as having four species: West Indian mahogany or small-leaved mahogany ( Swietenia mahagoni (L.) Jacq.), big-leaf mahogany ( Swietenia macrophylla King), Honduran mahogany ( Swietenia humilis Zucc.) and Swietenia × aubrevilleana StehlĂ© & Cusin. The debate over the number of taxa in the genus is still not resolved. Some researchers believe that there are only two species: S. mahagoni and S. macrophylla . I agree with that opinion and the two species can only be differentiated by the size of the leaves. All species in this genus have similar morphology except for leaf size. The following is the key to identifying these two species. S. mahagoni has a stalk length of around 37 cm with 5-6 pairs of strands. The strands are about 10 cm long and about 3.5 cm wide. S. macrophylla has a stalk length of up to 45 cm with 4-5 pairs of strands. The strands are up to 31 cm long and up to 8 cm wide. By Aryo Bando...

Aquatic bacteria Comamonas testosteroni eats plastic waste into carbon for microbial growth

NEWS - Researchers report an enzyme that breaks down polyethylene terephthalate (PET) in a somewhat unlikely place: Comamonas testosteroni , a microbe that lives in sewage sludge. The enzyme could be used by wastewater treatment plants to break down microplastic particles and recycle plastic waste. Plastic pollution is everywhere, and it mostly consists of PET. The polymer is used to make bottles, containers and even clothing. PET beads are an increasingly common microplastic found in places ranging from remote oceans to inside our bodies. But the particles are so small that they can escape water treatment processes and end up in wastewater that re-enters the environment. On the other hand, wastewater also contains microorganisms that like to eat these plastic particles, including C. testosteroni, so named because it degrades sterols like testosterone. “It’s important to note that PET plastic represents 12% of global plastic use. And it accounts for up to 50% of microplastics in wastew...
