Bamboo orchid (Arundina graminifolia)

Bamboo orchid (Arundina graminifolia) is a plant species in Orchidaceae, perennial terrestrial orchid, reed stems standing upright or horizontal, tubular, up to 2 m high, forming large clumps on forest slopes, agricultural land, plantations, roadsides and abandoned land.

A. graminifolia has linear leaves, grows along the stem, seated opposite, oblong lanceolate, 9-19 cm long, 1-1.5 cm wide, thick, a vein in the middle, pointed tip, amplexicaul sheath and dark green.

Clusters of flowers in slightly open terminals up to 10 buds, blooming successively at the terminals, 7-16 cm long. The flowers are 5-8 cm in diameter, reddish purple in color and white disc with purple lips. The bracts are broad triangular in shape and surround the main stalk of the flower bunch.

Fertilized seed pods will form small powdered seeds and small plants often develop near the tips after flowering, most likely aiding propagation if allowed to reach the ground.

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
