branching may repeat itself from the axillary bud of the prophylls in each flowering axis of the following order, and then some partial florescences (cymes) may show a complex structure (Rua, 1999).
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.
, 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.
