Varietal Perplexed in determining what differences to consider as specific, and what as varietal.Darwin. Varietas Variety Variety is nothing else but a continued novelty.South. The variety of colors depends upon the composition of light.Sir I. Newton. For earth this variety from heaven.Milton. There is a variety in the tempers of good men.Atterbury. He . . . wants more time to do that variety of good which his soul thirsts after.Law. Varieties usually differ from species in that any two, however unlike, will generally propagate indefinitely (unless they are in their nature unfertile, as some varieties of rose and other cultivated plants); in being a result of climate, food, or other extrinsic conditions or influences, but generally by a sudden, rather than a gradual, development; and in tending in many cases to lose their distinctive peculiarities when the individuals are left to a state of nature, and especially if restored to the conditions that are natural to typical individuals of the species. Many varieties of domesticated animals and of cultivated plants have been directly produced by man. These may be viewed as variations from the typical species in its most perfect and purest form, or, as is more commonly the case, all the forms, including the latter, may rank as Varieties. Thus, the sapphire is a blue variety, and the ruby a red variety, of corundum; again, calcite has many Varieties differing in form and structure, as Iceland spar, dogtooth spar, satin spar, and also others characterized by the presence of small quantities of magnesia, iron, manganese, etc. Still again, there are Varieties of granite differing in structure, as graphic granite, porphyritic granite, and other Varieties differing in composition, as albitic granite, hornblendic, or syenitic, granite, etc. |
