The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. [1] Examples of pseudanthia include flower heads, composite flowers, [2]: 514 or capitula, which are special types of inflorescences [3] in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped ...
[43] [44] [45] According to Aubreville, The capitulum can be up to 20 inches (51 centimeters) in width and up to 33 pounds (15 kilograms) in weight. [46] The largest globular capitulum (domesticated) is the Jakfruit (Artocarpus heterophyllus) grown throughout southern Asia and the East Indies. The largest Jakfruit reported in a reliable journal ...
Compound inflorescences are composed of branched stems and can involve complicated arrangements that are difficult to trace back to the main branch. A kind of compound inflorescence is the double inflorescence, in which the basic structure is repeated in the place of single florets. For example, a double raceme is a raceme in which the single ...
Asteraceae species are generally easy to distinguish from other plants because of their unique inflorescence and other shared characteristics, such as the joined anthers of the stamens. [7] Nonetheless, determining genera and species of some groups such as Hieracium is notoriously difficult (see "damned yellow composite" for example). [8]
A cyathium (pl.: cyathia) is one of the specialised pseudanthia ("false flowers") forming the inflorescence of plants in the genus Euphorbia (Euphorbiaceae). A cyathium consists of: Five (rarely four) [citation needed] bracteoles. These are small, united bracts, which form a cup-like involucre. Their upper tips are free and cover the opening of ...
Balanophora involucrata of the Himalayas has a capitate inflorescence with myriads of tiny flowers each measuring only 1/1,000th of an inch (25 micrometers) in width. [5] The capitulum can contain as many as ten million (10,000,000) florets. [6] Each floret weighs approximately seven micrograms (about 4,000,000 to the ounce). [7]
The generic name Cosmos derives either from the Greek κόσμος (cosmos) ‘(ordered) world’ -in reference to the neat, orderly arrangement of the floral structures [5] - or the Greek κόσμημα (kósmima) ‘jewel’ - in reference to the jewel-like colours of the capitula (composite flowers).
Arranged on a conical surface (like a snail shell); used to describe inflorescence s in which the bud s are arranged in an almost helical manner on the outside of a long, tapering, conical rachis. bract A modified leaf associated with a flower or inflorescence and differing in shape, size, or color from other leaves (and without an axillary bud ...
