Elephant ear tree (Enterolobium cyclocarpum)

Sengon buto or elephant ear tree (Enterolobium cyclocarpum) is a species of plant in the Fabaceae, a medium to large tree, 25-35 m high, 3.5 m trunk diameter, umbrella-shaped crown, dry season sheds all leaves and circular pods.

E. cyclocarpum has a cylindrical stem, has many branches from a height of 2 meters, the bark is light gray with reddish brown vertical gaps. Old trees often show damaged, chipped or scarred bark.

Leaves compound bipinnate, 15-40 cm long, 17 cm wide, petiole 2-6 cm with 4-15 pairs of pinnae, each pinna with 40-70 leaflets. Leaflets are slender oblong, 8-15 mm long and 2-4 mm wide.

Globular inflorescences in the axils of new leaves, each head consisting of 50 individual flowers with thousands of thin, filamentous stamens. Each flower consists of 20 stamens and one pistil, very fragrant up to several meters in all directions.

The fruit has a diameter of 7-12 cm, dark brown, shiny, not broken, spiral-shaped like a round disc. The fruit is made of thick soft tissue, containing 8-20 seeds arranged radially. Seeds are 14.5-17.5 mm long, 7.8-11.2 mm wide, 6.2-7.2 mm thick, brown with light brown or orange rings and very hard.

Tolerant of various levels of rainfall, temperature and soil conditions. Most grow in the lowlands in tropical habitats. Widely used as an ornamental tree, shade, shade and create many oases in the hot plains and slopes. The wood is reddish brown in color, light and water resistant.

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
