Information about Staminode
In botany, a staminode is an often rudimentary, sterile or abortive stamen. This means that it does not produce pollen. Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla.
Sometimes, the staminodes are modified to produce nectar, as in the Witch Hazel (Hamamelis).
Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus Paphiopedilum, and among the penstemons.
In the case of Cannas the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements.

Pollen is a fine to coarse powder consisting of microgametophytes (pollen grains), which produce the male gametes (sperm cells) of seed plants. The pollen grain with its hard coat protects the sperm cells during the process of their movement between the stamens

Nectar is a sugar-rich liquid produced by plants. It is produced either by the flowers, in which it attracts pollinating animals or by or extrafloral nectaries, which provide a nutrient source to animal mutualists providing anti-herbivore protection.
