The flower is bisexual and has three stamen and carpel
have three branched stigma.
The total fusion of carpels
until the middle of the ovary length (synascidiate), the partial division on the upper side and on the style (symplicate) and the trifid stigma were characteristics observed in this study for both species and described for all the studied species by Weckerle and Rutishauser (2005).
In Erythroxylaceae and some Linaceae only one of the three carpels
is fertile, which makes the flowers monosymmetric by reduction (Matthews & Endress, 2011).
Pentandrae is supported by the consistent presence of two synapomorphies, the five stamens and the tire carpels
The fruit presents two dehiscence regions: dorsal dehiscence (Figuras 3A and B; 5A and B), and other one that occurs along the carpel
sutures (Figuras 3A, 4B and 5A).
Two hundred years later the notion that sepals, petals, stamens and carpels
are all modified leaves got its molecular validation.
Those containing only stamens are logically called staminate flowers, and those lacking stamens but having carpels
are termed either pistillate or carpellate.
was detached from each capsule and the seed removed.
When fitting the model, I included the total number of carpels
initially produced by the plant (summed over all its flowers) as a covariate to account for differences between plants in their inherent potential for seed production.
A pistil may consist of a single carpel
or of two or more carpels
partly or completely joined together, enclosing the ovules.
They developed before the advent of bees and produce no nectar but attract their pollinators - beetles - with sweetly scented sugary secretions~*~ Their coloured "petals" are not Magnolia petals at all but carpels
thick enough stellata is a to dissuade pollinating beetles from spectacular tucking in.
In all four genera of Dasypogonaceae, flowers are trimerous and pentacyclic, with six tepals in two alternating whorls, six stamens in two alternating whorls and a central gynoecium that is normally composed of three fused carpels
located in the same floral sectors as the outer stamens and outer tepals.
