When the common dandelion is regarded as including all those small species, the names of all those species are heterotypic synonyms of Taraxacum officinale F.H.Wigg. Reducing a taxon to a heterotypic synonym is termed "to sink in synonymy" or "as synonym". In botany, although a synonym must be a formally accepted scientific name (a validly ...

Such tissue is commonly formed, for example, at the base of a petiole or pedicel. acaulescent Having no apparent stem, or at least none visible above the ground surface. [2] Examples include some species of Oxalis, [5] Nolina, [6] and Yucca. [7] Antonym: caulescent (possessing stem). accrescent
junior synonym, (zoology): any later name; homotypic synonym (botany) heterotypic synonym (botany): (or "taxonomic synonym") a synonym that comes into being when a taxon is reduced in status ("reduced to synonymy") and becomes part of a different taxon; the zoological equivalent is "subjective synonym" objective synonym (zoology)
The formation of woody tissue is an example of secondary growth, a change in existing tissues, in contrast to primary growth that creates new tissues, such as the elongating tip of a plant shoot. The process of wood formation ( lignification ) is commonest in the spermatophytes (seed bearing plants) and has evolved independently a number of times.
The term "basionym" is used in botany only for the circumstances where a previous name exists with a useful description, and the International Code of Nomenclature for algae, fungi, and plants (ICNafp) does not require a full description with the new name. [8] A basionym must therefore be legitimate. Basionyms are regulated by the code's ...

The following is a list of tautonyms: zoological names of species consisting of two identical words (the generic name and the specific name have the same spelling). Such names are allowed in zoology, but not in botany, where the two parts of the name of a species must differ (though differences as small as one letter are permitted, as in cumin, Cuminum cyminum).
