Definition
Heteroicous describes certain liverworts (a type of bryophyte) where the male and female reproductive structures are located on DIFFERENT branches of the SAME plant. Think of it like a 'house' (the plant) with 'different' (hetero-) sections for the sexes. It is a specific term within bryology, mostly focused on liverworts. It's a clever design ensuring some level of outcrossing and genetic diversity. The ‘hetero-’ prefix suggests the ‘different’ locations.
