Mary grass (Setaria barbata)

Mary grass (Setaria barbata) is a herbaceous species in the Poaceae, perennial grass, ribbon leaves, leathery with linear folds, green, hairy, grows wild in the shade, widely cultivated as an ornamental plant, some cultivars have striped leaves and purple midrib.

S. barbata has stems that grow from an elaborate rhizome, 1 cm thick and hairy. Leaves sparse to completely hairy, linear blades, oval or lance-shaped. Sharp tip, a vein in the middle, pleated texture and coarse or hairless hair.

The grains in panicles, yellowish green, open and spreading. The spikelets are several millimeters long and are often accompanied by hairs.

The grass is vigorous and spreads through rhizomes and seeds, forming monotypic stands. Cultivated as an ornamental plant for its palm-like pleated leaves. Some cultivars have striped leaves and have purple midribs.

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
