associated with an increase of fifty percent in the number of cotyledons and
leaves. The distributions show, however, that this is only an incomplete, and to
some extent an erroneous, statement of the condition. In the dimerous seedlings

Flowers on the Tree of Life
ancestor of mesangiosperms (Figs 4.1B, 4.2B, 4.4), but their merism is equivocal:
either dimerous or trimerous. In Ranunculales, if eudicots were originally
dimerous, Papaveraceae retain the ancestral state, and a reversal to trimery
occurred ...

The modal number of primary double bundles in the region of transition from root
to stem structure at the base of the hypocotyl is four in the dimerous and six in the
trimerous and hemitrimerous seedling. In the normal seedlings more than four ...

Text-book of Botany: Morphological and Physiological
But other dimerous and tetramerous flowers exhibit a more considerable
deviation from the type, inasmuch as the two dimerous perianth-whorls which
develope as if they were a tetramerous calyx or corolla are followed by a staminal
whorl ...

Homoplasy: The Recurrence of Similarity in Evolution
Dimerous androecia may be homoplastic in Piperaceae. amerous (Zippelia,
Piper) to trimerous (Macropiper) and dimerous (Peperomia, Pothomorphe). They
mapped the separate origin of dimerous androecia in Peperomia and
Pothomorjfloe ...

In the Ranalean complex, however, co-occurrence of the pentamerous, trimerous

Clematis with a dimerous perianth, a whorled arrangement of outer stamen

recognized until recently is a shift from trirnerous to dimerous flowers, with parts
in whorls of two (Drinnan et al. 1994; Endress & Doyle 2009). It is equivocal
whether ...
