12d we have shown the common ancestor of Canrightia and Chloranthaceae as having three free carpels and the syncarpous gynoecium of Canrightia as an autapomorphy (in terms of parsimony this is equivocal, since the syncarpy character is undefined in unicarpellate taxa).
Consequently, it is considered to be a derived syncarpous ovary as described by Lersten (2004).
This may be because an increase in carpel number in a syncarpous gynoecium has less effect on the general appearance of flowers than does an increase in number of free stamens.
A second case of "unorthodox" evolutionary direction is the evolution of apocarpous gynoecia from syncarpous ancestors.
Although the "Ambelanieae" and "Macoubeeae" have a syncarpous ovary and seeds embedded in pulp, whereas in the Tabernaemontaneae the ovary is usually apocarpous and the seeds displayed with (often brightly colored) arils, the close relationship of these three tribes is well supported by morphological, chemical, and molecular evidence (Fallen, 1986; Zhu et al., 1990; Endress et al., 1996; Sennblad & Bremer, 1996; Sennblad, 1997; Civeyrel et al., 1998).
These tendencies include: corolline corona often present, anthers sometimes with conspicuous sterile apical (sometimes also basal) appendages, ovary often syncarpous to varying degrees, and pollen sometimes porate and sometimes in tetrads.
The Brunelliaceae also has an apocarpous gynoecium, although in most other families of the Cornales-Rosales-Saxifragales complex the ovary is syncarpous. The Hydrangeaceae, which seems to have had a common origin with the Escalloniaceae (Takhtajan, 1983), has opposite rather than alternate leaves.
Gynoecium 2(-9) carpellate, but usually bicarpellate or occasionally 5-8-merous, rarely pseudomonomerous; syncarpous or apocarpous, (1-)2(-9) 1ocular; usually axile or parietal placentation, rarely free central, basal or apical; superior, semi-superior or inferior.
