The word calyx was adopted from the Latin calyx, [8] not to be confused with calix 'cup, goblet'. [9] The Latin calyx is derived from Greek κάλυξ kalyx 'bud, calyx, husk, wrapping' (cf. Sanskrit kalika 'bud'), [10] while calix is derived from Greek κύλιξ kylix 'cup, goblet'; both words have been used interchangeably in botanical Latin ...

calyx. pl. calyces. Collective term for the sepal s of one flower; the outer whorl of a flower, usually green. Compare corolla. calyx tube A tube formed by the fusion of the sepals (calyx), at least at the base. cambium Tissue layer that provides partially undifferentiated cells for plant growth. campanulate Bell-shaped. camptodromous
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.
In a mature flower, the perianth consists of a calyx and the corolla (petals) it supports. Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the corolla.
Floral diagram of Anagallis arvensis. [1]: 307 The dot represents the main axis, green structure below is the subtending bract.Calyx (green arcs) consists of five free sepals; corolla (red arcs) consists of five fused petals.
A series of bracts subtending the calyx (see below) is an epicalyx. Angiosperms are dealt with in more detail here; these structures are very different in gymnosperms. [7] In angiosperms, the specialised leaves that play a part in reproduction are arranged around the stem in an ordered fashion, from the base to the apex of the flower.
In angiosperms, a hypanthium or floral cup [1] [2] [3] is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. [citation needed] It often contains the nectaries of the plant.
