English naturalist who studied the plants and animals of South America and the Pacific islands, and in his book On the Origin of Species by Means of Natural Selection () set forth his theory of evolution nature provides variation among different organisms, humans select and breed for those variations that they find useful. Starting point. Before , most biological catalogues had used polynomial names for the taxa included, including earlier editions of Systema first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of Systema International Commission on Zoological Nomenclature therefore chose the 1st of January . Ray florets form outer part of the flower and they look like typical petals. Each ray or disk florets is an individual flower made up of a stamen, carpel and ovary. The ray florets, however, are sterile. Only the disk florets are fertile. Each carpel contains one or more ovaries, which house the female reproductive components of the daisy.

Zinnias are annuals, meaning that they go from seed to flower to seed quickly. Zinnias' pointy seeds, shaped like little arrowheads, require only basic garden prep to sprout: sow them in well-drained soil, where there's full sun and lots of summer heat, and you'll have tiny.

A radiate head has disc flowers surrounded by ray flowers. A ligulate head has all ligulate flowers. When a sunflower family flower head has only disc flowers that are sterile, male, or have both male and female parts, it is a discoid head.

Disciform heads have only disc flowers, but Clade: Angiosperms. Inflorescences in the Asteraceae plant family, flower heads, or capitula, mimic single flowers but are highly compressed structures composed of multiple flowers.

The edible seeds are an important source of oil. David Don, in I (8), published his account of the ligulate ray in Zinnia, and drew definite conclusions as to the nature of this organ. In I, Friedrich Haenlein (i6), published his contention that the bilabiate corolla showed a development intermediate between that of the ray corolla and that of the tubular or disk corolla.
