Editing Strongylodon macrobotrys (section)

=== Flowers ===
[[File:Jade Flor.jpg|thumb|Close-up of the flower.]]
The claw-shaped or beak-shaped flowers are carried in pendent [[Raceme|trusses or pseudoracemes]] of 75 or more flowers. The trusses can reach as much as 3&nbsp;m long.<ref name="Kew"/> The [[Turquoise (color)|turquoise]] flower color is similar to some forms of the minerals [[turquoise]] and [[jade]], varying from blue-green to mint green.

The flowers hang like clusters of grapes from [[inflorescence]]s produced by mature vines. Each bloom resembles a stout-bodied butterfly with folded wings; they have [[evolution|evolved]] certain modifications to allow them to be pollinated by a species of [[bat]] that hangs upside down on the inflorescence to drink its [[nectar]].<ref name="Kew"/><ref name=PotW>{{cite web |url=http://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:519595-1 |title=''Strongylodon macrobotrys'' A.Gray |publisher=Plants of the World Online |accessdate=23 June 2021}}</ref>

Their bright coloration is an example of [[copigmentation]], a result of the presence of [[malvin]] (an [[anthocyanin]]) and [[saponarin]] (a [[flavone]] [[Glucoside#Styrolene derivatives|glucoside]]) in the ratio 1:9. Under the [[alkali]]ne conditions ([[pH]]&nbsp;7.9) found in the [[sap]] of the [[epidermis (botany)|epidermal]] cells, this combination produced a pink pigmentation; the pH of the colorless inner floral tissue was found to be lower, at pH&nbsp;5.6. Experiments showed that saponarin produced a strong yellow colouring in slightly alkaline conditions, resulting in the greenish tone of the flower.<ref name="Takedaa"/>
