DENDROLOGY

Detailed explanation-1: -Linnaeus created the system of “binomial nomenclature, ‘’ which uses only two designations–genus and specific epithet as the species name. In the mid-1800s, scientists agreed on an expanded system of nomenclature.

Detailed explanation-2: -For proper identification, samples should include any plant material visible above the soil such as branches, leaves, flowers, seedpods, and fruit. Branch and leaf orientation are important identification characteristics, so include a section of stem containing several buds (1 to 2 feet of branch growth).

Detailed explanation-3: -In general, organisms are identified by their binomial name, consisting of the genus and species names. The genus name is always capitalized, whereas the species name is not. Both names are always italicized or underlined. Genus names can be abbreviated by their first letter, but species names cannot.
