Perianth usually composed of similar or subsimilar segments in two or one series, usually very conspicuous and petaloid and if united then connate in the lower part into a single tube, but if perianth of separate calyx and corolla then the branches modified into cladodes or else herbs or woody climbers or shrubs with one-celled ovary and six stamens or perianth dry and fruit dehiscent or else stamens three, two, or one on a column. 

Connation and Adnation.—In the development of the flowers of primitive species of flowering plants, the parts of each whorl are disjoined or separate from each other. In many higher types, however, the parts of the same whorl frequently become partly or completely united laterally. This condition is termed connation, coalescence, cohesion or s)mgenesis. Illustrations of this ihay be seen in Belladonna, Stramonium and Uva Ursi flowers, where the petals have joined laterally to form gamopetalous corollas. When the one or more parts of different whorls are united, as of stamens with petals Rhammus) or stamens with carpels Apocynum) the union is called adnation or adhesion.

Based on our data set, there are no unequivocal changes in floral characters on the line from the base of the mesangiosperms to the common ancestor of Canellales and Piperales. If mesangiosperms originally had a trimerous androe-cium, as inferred when phyllotaxis and merism are treated as separate characters, there was an increase in the number of stamens per whorl in Canellales (i.e. the androecium became polymerous), followed by connation of the stamens into...
