From mapping ecological relationships and traits of ecological significance onto representative maximally parsimonious phylogenies and the consensus tree, I inferred that resin secretion by floral bractlets originated prior to its role as a pollinator reward.
The homologous bractlets later assumed the role of secreting the reward resin, which is collected by pollinating female bees [ILLUSTRATION FOR FIGURE 1 OMITTED].
About the time resin secretion by floral bractlets became associated with reward rather than defense functions, the involucral bracts evolved larger size and often bright colors, apparently as a floral advertisement to pollinators [ILLUSTRATION FOR FIGURE 3 OMITTED].
The bractlets homologous to those that make up the resin gland are present and, in D.
The switch from a pollen or fragrance reward to a resin reward may have been facilitated by the fact that these primitive Dalechampia apparently produced triterpene resin from both the pistillate sepals and protective bractlets of the male subinflorescence.
