Likewise the genus Hibiscadelphus is--to my knowledge--the only genus in Malvaceae-Malvoideae with a consistently monosymmetric corolla and androecium.
Hibbertia (Dilleniaceae) has different kinds of monosymmetry: some species have a single carpel, some species have a monosymmetric androecium, this monosymmew being median or transversal (Tucker & Bernhardt, 2000; Horn, 2006, 2007, 2009).
where it is predominantly expressed in the floral cup, androecium and gynoecium (Prance & White, 1988; Matthews & Endress, 2008), some Ochnaceae, where it occurs together with buzz pollination (Amaral, 1991), and some Violaceae, in which the anterior petal has a spur, which surrounds the nectaries formed by two stamens, and the stigma has a monosymmetric pollen collection mechanism (Melchior, 1925; Beattie, 1969).
Table 1 Diversity in the expression of floral monosymmetry Organ categories are affected in various combinations * All organs (corolla and androecium are generally the most obviously affected regions) (e.
To see their emergence, the surrounding calyx, corolla, and androecium must be mechanically removed (e.
On the development of the androecium in Cochliostema, Lem.
Androecium number: diplostemonous=0; obdiplostemonous= 1; haplostemonous=2; numerous stamens=3.
This is also reflected by the fact that they have different androecium initiation patterns.
This is also indicated by disparate patterns of androecium development.
A typical example of heterotopic staminodes are petals, if petals are considered a category different from the androecium.
As those structures have often been described as staminodes in the literature, the resulting misinterpretations can have far-reaching consequences for the definition of character states used in data matrices, and they can mislead hypothetical semophyleses of the androecium.
