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 ...
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 ...
[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 ...

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 ...
Each is a "head" or capitulum 2–7.5 cm (3 ⁄ 4 –3 in) wide. [3] Each head has between fifteen and forty white "petals" (ray florets) 1–2 centimetres (3 ⁄ 8 – 3 ⁄ 4 in) long surrounding the yellow disc florets. Below the head is an involucre of glabrous green bracts 7–10 millimetres (1 ⁄ 4 – 3 ⁄ 8 inch) long with brownish edges.
Some familiar and seemingly actinomorphic so-called flowers, such as those of daisies and dandelions , and most species of Protea, are actually clusters of tiny (not necessarily actinomorphic) flowers arranged into a roughly radially symmetric inflorescence of the form known as a head, capitulum, or pseudanthium.
capitulum (plural capitula) may refer to: the Latin word for chapter. an index or list of chapters at the head of a gospel manuscript; a short reading in the Liturgy of the Hours. derived from which, it is the Latin for the assembly known as a chapter; a typographic symbol (⸿), to mark chapters or paragraphs, now evolved into the pilcrow
