Most Trees Common: Most trees common trees have common names in the language of their country. Some common names, such as those of United States trees and lumber trade names, have been standardized. However, common names change in different places, countries, and languages, or may be indefinite, while the same terms may be repeated for different trees. For precision, stability, and uniformity, foresters and botanists use the scientific or botanical names, which are governed by an international code of rules and universally accepted.
Under the system of naming called binomial nomenclature, the scientific name of a species or kind of tree or other plant consists of two words in Latin form, the generic name (genus) and specific epithet (species), such as, Pinus echi-nata, shortleaf pine.
Fruit growing in North America began with the introduction of fruits by the earliest settlers. Orchards were apt to be a conglomerate but cherished collection of many different trees. Propagation by seed was a common practice among the Indians and seedling orchards formed an integral part of the Indian village. A modern planting made up of trees differing entirely from each other is unthinkable but in early colonial days such orchards were quite common.
The small trees are only 15 to 30 feet high and the large shrubs are scattered and often far apart, Most trees commonly spiny and with small, usually deciduous, leaves. Common leguminous trees such as acacia (Acacia) and mesquite (Prosopis) have flat-topped crowns like parasols of thin, delicate foliage. Fleshy evergreens, or stem succulents, are common. Cacti are familiar New World examples, replaced in the Old World by euphorbias and unrelated plants of similar habit. Annual herbs appear after rains.
