In some taxa one or more stamens will initially form but will be nonfertile. Such a sterile stamen is termed a staminode or staminodium. Staminodes may resemble the fertile stamens and can only be identified by determining if viable pollen is released.
This article aims to discuss the shortcomings of the past and current approach of staminodes and proposes definitions of staminode types for use as characters in phylogenetic analyses. Staminodial structures should be classified according to their position and function in the flower.

staminode is a sterile stamen, or a modified structure identifiable as such, borne in the androe- cial region of the flower. It may be merely imperfect, vestigial, or specialized (e.g., petaloid or nectariferous). For Mione and Bogle (1990: 78), studying Hamamelidaceae, staminodes are
This study presents the first morphological overview of staminodes in the Cactaceae, rendering a wider perception of the variability in patterns of floral parts in this plant group and broadening the meaning of the term staminode is discussed along with the putative origin of these appendages.
24 kwi 2020 · A recent study by Meaders and colleagues (2020) aimed to figure out how exactly the staminodes of Aquilegia develop, and what role they might play in the plant’s floral ecology. Aquilegia is a genus of approx. 70 species in the family Ranunculaceae.
