The most primitive flowers are thought to have had a variable number of flower parts, often separate from (but in contact with) each other. The flowers would have tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers ...
Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of angiosperms, are the most varied physically and show a correspondingly great diversity in ...

The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. [2] They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large ...
Its individual flowers (florets) within the flower head are hermaphroditic, having both male and female organs in each flower. It is pollinated by butterflies and bees. The alternate leaves, borne by a petiole from 0 to 17 cm, are oval to lanceolate , 5-30 x 5-12 cm; the margin is tightened to toothed.
The flowers are fragrant and hermaphroditic, surrounded by five unequal, thinly veined, yellowish-white petals. The flowers are about 1–1.5 cm (3 ⁄ 8 – 5 ⁄ 8 in) long and 2 cm (3 ⁄ 4 in) broad. They grow on slender, hairy stalks in spreading or drooping flower clusters, which have a length of 10–25 cm (4–10 in). [8]
