"What is the term used to describe the collection of flowers in species that have more than one flower on an axis (sometimes called ""composite flowers""?"
Flower The apex of a flowering stem forms a terminal swelling which is called the "torus" or receptacle. In those species that have more than one flower on an axis, the collective cluster of flowers is termed an "inflorescence". Some inflorescences are composed of many small flowers arranged in a formation that resembles a single flower. The common example of this is most members of the very large composite (Asteraceae) group. A single daisy or sunflower, for example, is not a flower but a flower "head"—an inflorescence composed of numerous flowers (or florets). An inflorescence may include specialized stems and modified
The Different Forms of Flowers on Plants of the Same Species is thus a triple chance of the maximum of fertility...There is thus the clearest proof that these complex arrangements have the important end of securing both a more abundant and more vigorous offspring.” Observations and experiments still continue today to further the understanding of this phenomenon instigated by Darwin in this original and seminal work. The Different Forms of Flowers on Plants of the Same Species The Different Forms of Flowers on Plants of the Same Species is a book by Charles Darwin first published in 1877. It is the fifth of his six books devoted solely to the study
