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)
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
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 ...
Other fields are denoted by adding or substituting the word botany (e.g. systematic botany). Phytosociology is a subfield of plant ecology that classifies and studies communities of plants. The intersection of fields from the above pair of categories gives rise to fields such as bryogeography (the study of the distribution of mosses).

The term "basionym" is used in both botany and zoology. [3] In zoology, alternate terms such as original combination [4] or protonym [3] [5] are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an i. [6] Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical ...
For example, when there is a loss of B gene function, mutant flowers are produced with sepals in the first whorl as usual, but also in the second whorl instead of the normal petal formation. In the third whorl, the lack of the B function but the presence of the C function mimics the fourth whorl, leading to the formation of carpels also in the ...
