The authors looked at three inflorescence structures that occur in nature: the panicle, the raceme, and the cyme
The flowers of yarrow are known as cymes
and appear as flat-topped clusters, up to 6 inches across in some varieties, of many small blooms.
At that time several plants had basal leaves and one plant retained an inflorescence in which the panicle of cymes
had begun to deteriorate.
Receptacles are said zygocarpic (composed or mixed), malacocarpic (cylindrical and smooth) or acanthocarpic (spiny), qualified of carpophylles or pseudocarpophylles, arranged in cymes
, racemes or glomerules.
Flowers occur in inflorescences of 2-4 (Jepson 1993) scorpioid cymes
and contain 5, partially-fused petals that form a star-shaped, 3-6 mm-broad white corolla (Munz 1974).
In January, it produces cymes
of white flowers with a tint of rose to lighten up a dark winter's day.
may then become increasingly compound and complex (as in Nelsia Schinz and Amaranthus species) (Townsend, 1993) owing to the development of the axillary bud of the prophylls of the lateral flowers of different order (Fig.
Capitulescences monocephalous or cymes
two- to four-headed, terminal; capitula sessile to short-pedunculate, homogamous, discoid; receptacle moderately paleate to epaleate; involucre multiseriate.

This adaptation to pollination by bees is supported in this group and in most of the species of the family, by strong protandry and by an inflorescence in the form of a contracted raceme of condensed cymes
(Dommee et al.
In Gesneriaceae, pair-flowered partial florescences terminating each cyme
are characteristic (Weber, 1973), but transitions to "normal" cymes
have also been found (Weber, 1978).
