An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern.
Iva annua, the annual marsh elder or sumpweed, is a North American herbaceous annual plant in the sunflower family that was historically cultivated by Native Americans for its edible seed.
A pseudanthium is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower head, composite flower, or capitulum, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large.

Mimetes hottentoticus is an evergreen, upright shrub of 1½–3 m (5–10 ft) high from the family Proteaceae. It has silvery, broadly egg-shaped to egg-shaped leaves with three small teeth crowded at the tip. The flower heads and subtending leaves form a cylindric inflorescence, topped with a tuft of smaller, more or less upright silvery or pinkish leaves. Each flowerhead contains 8–12 flowers with conspicuously red styles, that are all parallel, projected straight up, pushing against the leaf subtending the higher flowerhead. The styles end in a short white zone topped by a thick blackish pollen presenter. Flowers can usually be found from January till March, few may persist into May. It is called silver pagoda or matchstick pagoda in English and Hottentotstompie in Afrikaans.
Mimetes stokoei, the mace pagoda, is an evergreen, upright, hardly branching, large shrub of 1–2 m high in the family Proteaceae. It has silvery, oval leaves of 5–8 cm (2.0–3.2 in) long and 2 1⁄2–4 cm (1.0–1.6 in) wide, with one large tooth supported by two smaller teeth near the tip, at an upward angle and somewhat overlapping each other. The inflorescences are set just below the growing tip, are cylinder-shaped, 10–12 cm (4–5 in) high, topped by a crest of small, more or less horizontal, pinkish-purple tinged leaves. It consists of several flower heads in the axils of golden leaves with a pinkish wash that form a hood shielding the underlying flower head. Each flower head contains eight to twelve individual flowers, with amber-colored styles topped by blackish purple pollen presenters and grey silky perianth lobes. It is endemic to the Fynbos ecoregion of South Africa, being confined to the Kogelberg mountain range. The mace pagoda was twice presumed extinct, but reappeared in its natural habitat from seed, after a wildfire several decades later.
