Different definitions can be applied for staminodes. For Watson and Dallwitz (1992-), a staminode is a sterile stamen, or a modified structure identifiable as such, borne in the androecial region of the flower. It may be merely imperfect, vestigial, or specialized (e.g., petaloid or nectariferous).
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.

the interpretation of staminode evolution. To examine the evolutionary history of staminodes, we determined an-droecial characters (number of stamen whorls, presence/absence of stami-nodes), floral design (symmetry, blossom type), primary pollen vector, and proposed staminode functionality (if found) for families considered by Chase
TLDR. 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.

We subdivided these staminodes into eight functional types: 1) Staminodes offering visual/olfactory cues; 2) Staminodes offering edible/inedible rewards; 3) Staminodes that deceive pollinators with false rewards; 4) Staminodes facilitating or directing the movements of pollinators in flowers;5) Stami nodes that facilitate stigma movement; 6) St...
1 lis 2000 · Staminodes are sterile stamens that lost pollen production, and presentation to new alternate functions, such as attracting pollinators, protecting the carpels, secreting nectar (staminal ...
