Homoplasy: The Recurrence of Similarity in Evolution
An extended literature search (of course not complete) resulted in the following
results for eudicots, ranunculids excepted (for an earlier review of trimerous
flowers see Li 1966). There are two different aspects for the level of expression of
...

Flowers unisexual, trimerous, bracteate; male with basally fused sepals, with a
short anthophore between sepals and petals, petals fused and with "epipetalous"
glands which may have some hairs; stamens 3 + 3, those of the outer whorl free,

Merosity Among basal angiosperms, many lineages have numerous parts, some
clades are trimerous, and others defy simple coding of merosity. In Winteraceae,
the outermost floral organs are in dimerous whorls, followed by a switch to ...

Flowers on the Tree of Life
As with the perianth, the ancestral state for androecium phyllotaxis (Fig 4.2A) is
equivocal: either spiral or whorled and trimerous. If the ancestral androecium was
spiral, it became whorled and initially either trimerous or polymerous in ...

The floral appendages arise centripetally in alternating trimerous whorls with
each successive whorl appearing at a higher level on the floral apex (Figures 6,7
). Both sexes first initiate a whorl of sepals followed quickly by a whorl of petals.

The Families of the Monocotyledons: Structure, Evolution, ...
The actinomorphic, trimerous flower type is undoubtedly the plesiomorphic state
in the monocotyledons. Zygomorphic flowers have arisen in many groups, often
in single genera within families where actinomorphic flowers prevail (Antheric- ...

Monocots: Systematics and Evolution: Systematics and Evolution
Stamens occur in two trimerous whorls in A. undulatum and A. natans, but the
stamens are not superposed over perianth members, rather they alternate with
them in a more conventional pattern. Then a whorl of three carpels alternates
with ...
