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.

Zinnia angustifolia Kunth (= Z. linearis Bentham), native to northern and western Mexico, is commonly grown as an ornamental in the United States and has been reported from Utah (S. Welsh et al. ); the record was likely from a cultivated source. The species also persists in gardens in California; it is not known outside of cultivation.
The whole head or capitulum is apparently similar to a single flower because the involucral bracts perform the function of protection. In Helianthus the outer or peripheral, ligulate and zygomorphic florets are called ray-florets; whereas inner or central, tubular and actinomorphic ones are called disc-florets.

Behind the surface of the “ideal” all-in-one live/work environment, there is a tightly regimented social order. And like all complex societies, it has its dissidents, misfits, and predators—including drug dealers, abusive managers, and others who don’t fit.
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.

Sunflowers are native primarily to North and South America, and some species are cultivated as ornamentals for their spectacular size and flower heads.
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.
