A mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone.
The stem of a plant, especially a woody one; also used to mean a rootstock, or particularly a basal stem structure or storage organ from which new growth arises. Compare lignotuber. caudiciform Stem-like or caudex-like; sometimes used to mean "pachycaul", meaning "thick-stemmed". caudicle diminutive of caudex.
In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
Diagram showing the parts of a mature flower. In this example the perianth is separated into a calyx (sepals) and corolla (petals) A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals.
The perianth is reduced to two scales, called lodicules, [1]: 11 that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. The flowers are usually hermaphroditic — maize being an important exception — and mainly anemophilous or wind-pollinated, although insects occasionally play a role. [2]

A floral formula is a notation for representing the structure of particular types of flowers.Such notations use numbers, letters and various symbols to convey significant information in a compact form.
Perianth of (3-)4(−8) tepals (sometimes interpreted as a dimerous and dichlamydeous perianth), in 1(−2) valvate whorls, sometimes elongated in a basal sack, free or fused in different ways (all fused or even one free and three basally to completely fused), or even connivent by marginally interdigitate papillae forming a tube or a bilabiate ...
