dioicus
/dy-OY-kus/🏷️ Taxonomy●● Intermediate
Also known as: dioica, dioicum
A reproductive epithet recording that a species keeps its sexes apart: staminate and pistillate flowers occur on different individuals rather than together on one plant. This is the masculine form, paired with masculine genus names. Appears as dioicus (masculine), dioica (feminine), or dioicum (neuter).
Example
“Aruncus dioicus (goatsbeard) takes the masculine ending to agree with the masculine genus name Aruncus, and sets seed only where both sexes are grown.”
