Malvales
A fony baobab tree (Adansonia rubrostipa), estimated to be more than 1,000 years old, in Madagascar.
In the order Malvales, stamen development begins with the formation of 5 or 10 initial swellings, or primordia, from which the numerous individual stamen primordia subsequently develop. A key characteristic of this process is that the first stamens to mature are located in the center of the flower, near the ovary.1
This differs significantly from the development observed in basal angiosperms such as the Magnoliales. While members of the Magnoliales also possess numerous stamens, their development occurs quite separately rather than from initial swellings. Furthermore, in Magnoliales, the first stamens to mature are those located near the petals, which is the opposite of the maturation pattern found in Malvales.1
