Monkey pod tree (Samanea saman)

Trembesi or rain tree or monkey pod tree (Samanea saman) is a species of plant in the Fabaceae, a large tree, 30-40 meters high, 4.5 meters in diameter, tree crown 40-60 meters, irregularly shaped trunk, sometimes bent and swollen big.

S. saman has compound leaves with stalks about 7-15 cm long, 4-5 cm wide, dark green in color, the lower surface is velvety and soft. The leaves will fold when it rains and at night.

Flowers are white and bright red spots on the top, 10 cm long from base to tip. The crown tube is 3.7 cm long and has 20-30 stamens 3-5 cm long. Nectar for insects are very fond of.

The pods are straight, slightly curved, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is dark brown when ripe. Seeds embedded in reddish-brown flesh, very sticky, sweet containing 5-25 seeds with a length of 1.3 cm.

Trembesi absorbs 28.5 tons of carbon dioxide every year which an ordinary tree absorbs only 1 ton in a 20 year lifetime. This tree is also able to reduce gas concentrations effectively, without reforestation and has a strong ability to absorb groundwater.

Indian rosewood (Dalbergia latifolia)

Sonokeling or Java palisandre or Indian rosewood ( Dalbergia latifolia ) is a species of plant in the Fabaceae, a large tree producing hardwood, medium weight and high quality, rounded leaves, thin and broad pods, highly adaptive, grows in dry and rocky landscapes with lots of sunlight. D. latifolia has medium to large size, cylindrical stems, up to 40 m high with a ring of up to 2 m, the bark is brownish gray and slightly cracked longitudinally. The crown is dense, dome-shaped and sheds leaves. The leaves are compound and pinnate oddly with 5-7 strands that have different sizes and appear alternately on the shaft. The leaves are round or elongated in width or heart, the upper surface is green and the surface is pale green. The flowers are small, 0.5-1 cm long and clustered in panicles. The pods are green to brown when ripe and are elongated lanceolate, pointed at the base and tip. The pods have 1-4 seeds which are soft and brownish. Indian rosewood grows at elevations below 600 m,

Evolution theory goes beyond

OPINION - As a Wallacean and Darwinian, I have always viewed life from the perspective of evolutionism. I see the world of plants and animals always using evolutionary theories. How a species develops functional organs, forms morphology, adapts to ecosystems and so on as a natural laws. This perspective ultimately forms my framework for thinking about various things, including the way I see myself, everyday problems and the way I think about big things such as economics, geopolitics, war and so on using an evolutionary perspective. Alfred Russel Wallace, Charles Darwin and Jean-Baptiste Lamarck are three great figures who really inspired me. They are well known as pioneers of evolutionary theories. They start from small things in the sub-subject of biology, although they also discuss geology and so on. Wallace focused on species adaptation and Darwin on sexual selection. Both developed evolutionary thinking using observational methods. Lamarck focused on structural morphology using l
