Siam bamboo (Thyrsostachys siamensis)

Bambu siam or siam bamboo (Thyrsostachys siamensis) is a plant species in Poaceae, bamboo that is clumped, upright stems, densely packed, green, pale green shoots or purplish, widely used for ornamental plants, living fences, wind barrier and bamboo shoots used for vegetables.

T. siamensis has straight stems or curved ends, 8-14 m tall, branches appear high above the ground with many branches in a segment where one is bigger than the other branches.

Dlium Siam bamboo (Thyrsostachys siamensis)

The segment has a length of 15-30 cm and a diameter of 2-7.5 cm. The walls are very thick, even solid at the bottom, smooth, grayish green, usually covered by a reed which is not falling out. The boundary of the segment is not prominent with the whitish ring just below the segment.

The reed is not loose, 20-25 cm long, 8-10 cm wide at the base and narrowed to 2.5 cm at the end, pale green or purplish with white hairs scattered on the outside, brown ends yellowish and thinning to dry.

The reed ears are not visible or are very small in size and loosened. The leaves of the reed are narrow lanceolate, 6-15 cm long, 5-12 mm wide, erect, have fine hairs on the axial and ligula are very short.

The leaves are long and narrow, 7-14 cm long, 5-10 mm wide, pale green which is whitish and generally lokos. Striped leaf midrib, white haired at a margin, midrib or small ear size. Ligula is very short, flat and smooth-haired.





Siam bamboo grows in the tropics, semi-evergreen forests, mixed or drier, dry, sandy, rocky forests, nutrient-poor soils, altitudes of 300-2000 m and rainfall of 800-1,000 mm/year. This bamboo grows on various types of soil that is not flooded.

Stems are used for general household use, materials for making baskets, chopsticks, umbrella handles, fishing rods, pulp and firewood. Shoots are praised as one of the most delicious vegetables. Popular to decorate parks and curbside, live fences and windbreaks.

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,...

Javan mocca or Javan slender caesar (Amanita javanica)

OPINION - Javan mocca or Javan slender caesar ( Amanita javanica ) is a mysterious fungus species and has been enigmatic since it was first reported by Boedijn in 1951 and after that no explanation or reporting of specimens is believed to be the same as expected. Boedijn (1951) described A. javanica which grew on Java island as having the characteristics covered in the Amanita genus. Corner and Bas in 1962 tried to describe Javan mocca and all species in Amanita based on specimens in Singapore. Over time some reports say that they have found A. javanica specimens in other Southeast Asia including also China, Japan, India and Nepal. But there is no definitive knowledge and many doubt whether the specimen is the same as described by Boedijn (1951). I was fortunate to have seen this species one afternoon and soon I took out a camera for some shots. In fact, I've only met this mushroom species once. Javan mocca is an endangered species and I have never seen in my experience in...

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...
