Lilies, such as the Tiger Lily, Lilium tigrinum, at the right, bear six stamens (composed of anthers and filaments), and one pistil (composed of the stigma, style and ovary). All this compares fairly well with the "typical" features of our Standard Blossom.
However, one feature different from our Standard Blossom is the flower seems to have a colorful corolla, but beneath that there is no green calyx with its sepals. In lily flowers, the colorful part is known as the perianth, and its parts, instead of being petals and/or sepals, are called tepals, a term used when a flower's corolla and calyx are are indistinguishable from one another. And lilies have six tepals, not the usual five petals and five sepals.
Our pictured Tiger Lily is member of the genus Lilium, in the Lily Family, the Liliaceae. Many plants are called lilies which don't belong to the genus Lilium, plus there's uncertainty among specialists as to how to define the Lily Family itself. For example, as of 2021, the Flora of North America considers both the genera Amaryllis and Crinum as members of the Lily Family, though most other web sites place them in the Amaryllis Family, the Amaryllidaceae.
This is one case in which the backyard naturalist may find is more agreeable just to use the common English names and not be concerned whether a crinum lily is a "true lily" or not.
