The construction of classifications, as well as the understanding of biological diversity, depends upon a careful comparison of attributes of the organisms studied (Stuessy, 1990). It is widely known that data from diverse sources showing differences from taxon to taxon are of systematic significance. During the 20th century, systematists have emphasized that their discipline involves a synthesis of all knowledge (Stevens, 1994) or, in other words, the variation of as many relevant characters as possible should be incorporated into the natural system to be constructed. The extent to which particular characters are constant or labile will determine their usefulness to systematics. In general, more conservative characters will be valuable in defining families and orders, whereas more labile characters may be useful at the generic and specific levels (Webb, 1984). There is no doubt that floral characters are among the most used in the classification of flowering plants. At the same time, they constitute essential features in diagnostic keys to taxa in both taxonomic treatments and Floras (Cronquist, 1981, 1988).

Nectary structure and ultrastructure (2007, background): “The term nectarium, introduced by Linnaeus (1735) and used also by Davis et al. (1998) for the complex nectary of Brassicaceae, can be used to describe all separated nectaries in a flower, whereas nectary represents the single unit (see also Bernardello, 2007, Chapter 2 in this volume).”
Beyond nectar sweetness: the hidden ecological role of non‐protein amino acids in nectar (2014, background): “In the majority of angiosperms, pollination involves animals for the transfer of pollen from the anther to the stigma (Pacini 2008), and this interaction is more frequently mediated by floral nectar (Bernardello 2007; Nicolson 2007).”
Flower Structure and Trends of Evolution in Eudicots and Their Major Subclades1 (2010, background): “They are not distinctly part of the calyx, corolla, androecium, or gynoecium (see also Smets, 1986; Endress, 1994; and especially Bernardello, 2007).”
Relationships between Tapetum, Loculus, and Pollen during Development (2010, background): “1) and that locular space and fluid (1) may always be minimal as in orchids with pollinia and all species with PDU consisting of multiples of four pollen grains held together by common walls; (2) may grow slightly as in orchids with monad pollen; (3) may grow slightly as in anemophilous gymnosperms;”
