Floral Diagrams: An Aid to Understanding Flower Morphology ...
Origins of pentamery are not well understood, although five-merous flowers are
found in the majority of angiosperms. There are at least five origins of pentamery,
the major one affecting the core eudicots (Ronse De Craene, Soltis and Soltis, ...

10.5). Dimery is often seen in early- diverging eudicots. However, trimery is also
prevalent (Ranunculales), and pentamery is seen in some taxa. In contrast, in
core eudicots, pentamery predominates. Interestingly, dimery is found in Gunnera
, ...

... types ; this being constant for such different phyla as the Cruci/erae,
Ouagraceae, Rubiaceae, &c, so that the presence of a diagonal corolla may be
taken as a very fair sign of a previous fuller condition of pentamery in the floral
formula.

His complaint is that single characters such as the calyptroid corolla and its
pentamery and tetramery have had assigned to them too much importance, and
that in consequence the apparent simplification by reduction of genera has led to
...

Tetramerous and hexamerous constructions are commonly found as irregularities
or variants on normal pentamery. Constant tetramery implies normal pentamery
as an antecedent phylogenetic condition ; in such a flower the calyx becomes ...

Homoplasy: The Recurrence of Similarity in Evolution
In Polygonaceae the gynoecium is constantly trimerous but androecium and
perianth fluctuate between pentamery and trimery (Galle 1977). In Hypericum (
Clusiaceae) the gynoecium is trimerous but the number of stamen groups
fluctuates ...

Flowers on the Tree of Life
Perhaps the best example ofa floral deep-node character is the number oforgans
that occur within each floral whorl, termed flower merism or merosity (Ronse De
Craene and Smets, 1994), especially five (pentamery) versus three (trimery), ...
