Amaranthaceae are characterized by having solitary flowers, cymose or variously compound (modified cymose) inflorescences, often subtended by bracts or bracteoles (Cronquist, 1981; Kadereit et al.
If the enrichment axes do branch, either a paniculate branching pattern (branches generated from the leaf axillary buds), or a cymose branching pattern (branches generated from the axillary buds of the prophyll) may occur.
Capitulescences monocephalous or lateral and cymose of three to seven heads; capitula short-pedunculate, homogamous, bilabiate, two- to six-flowered; receptacle epaleate; involucre multiseriate, cylindrical, phyllaries woolly.
Capitulescences cymose, two- to nine-headed, subterminal to lateral, rarely monocephalous; capitula pedunculate, homogamous, bilabiate, two- to five-flowered; receptacle epaleate; involucre multiseriate, cylindrical, phyllaries glabrous.
Capitulescences monocephalous, terminal, less commonly cymose, with few to many capitula.
In Fabaceae (Leguminosae), the basic inflorescence type is a raceme, but evolutionary shifts have led to pseudoracemes in five tribes of Papilionoideae (Tucker, 1987) and to cymose inflorescences in a few taxa, including caesalpinioid Dialium and related genera (Tucker, 1998; other cymose legumes are discussed therein).
An alternate view to an indeterminate inflorescence as a precursor for the typical asteraceous capitulum was suggested by Cronquist (1977), who proposed that the ancestors to the Asteraceae had a cymose (determinate) inflorescence that was condensed into a head, which then "was gradually converted" from the cymose or determinate state to the racemose or indeterminate state.
In these families it is quite common to find that the development of a cymose cluster of flowers in the axil of a bract is terminated by the formation of a vegetative bud in place of the last flower, or in some cases a vegetative bud occurs directly in the bract axil.
