Elaioser

Elaioser is a fictional genus used in speculative biology and science-fiction contexts to illustrate plant–ant mutualisms involving oil-rich seeds. It is not recognized by any taxonomic authority and has no standing outside of narrative or educational simulations.

The name elaioser is derived from elaios, Greek for oil, combined with a conventional taxonomic suffix to signal its imagined status as a seed-bearing plant. In most depictions, the term signals a group of plants whose seeds carry lipid-rich tissues designed to attract ants.

Elaioser plants are described as small to medium shrubs with glossy evergreen leaves. They produce seeds encased in an edible, lipid-rich elaiosome that attracts seed-dispersing ants. The interactions are typically described as myrmecochory, with ants carrying seeds to nests where the elaiosome is consumed and the seed germinates later. Flowers are generally inconspicuous, and pollination is attributed to generalist insects.

In fictional world-building, elaioser occupies Mediterranean to semi-arid habitats where oil-rich seeds and ant mutualisms are common. Their lipid-focused metabolism is depicted as drought-tolerant, contributing to resilience in arid conditions and shaping local ecological networks in the imagined ecosystem.

Origins and usage: The concept appears in speculative biology literature and role-playing settings, used to illustrate coevolution and seed-dispersal strategies. There is no empirical data or real-world observation supporting elaioser.
