Chinese hibiscus (Hibiscus rosa-sinensis)

Kembang sepatu or bunga raya or worawari or Chinese hibiscus (Hibiscus rosa-sinensis) is a species of shrub in Malvaceae, growing 2-5 m high and 1-3 m wide, having ovoid leaves, acute tips, jagged edges, shiny, and solitary. Widely planted as an ornamental plant in the tropics and subtropics, large flowers, red and odorless.

H. rosa-sinensis has a variety of cultivars and hybrids including single or double flowers that are white, yellow, orange and red. Flowers come all year long, large, conspicuous, trumpet-shaped, five petals with a diameter of 4-18 cm and anthers red orange.

Chinese hibiscus includes dicotyledonous, solitary, complete and perfect, has superior ovaries, regular symmetry and axillary placentation, 5 carpels, 5 loci, 5 sepals and varying amounts of stamens. The base of the flower is green petals and the pointed tip of the petals is sepals.

The male and female parts of the same flower. The five hairy red spots at the top of the flower are the stigmas in which pollen is collected. The ovary is located at the bottom of the flower. The male part consists of stem-like filaments and each filament ends with pollen-producing anther. Anthers sit on filaments and these two organs form hundreds of stamens.

This flower is used in hair care, shoe polish and can be used as a pH indicator where an acidic solution makes the flowers turn pink, dark or magenta. Flowers extracted for cosmetics, skin care and anti-solar agents.

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
