olettamus

Olettamus is a fictional genus of flowering plants created for illustrative purposes in a taxonomic encyclopedia. It currently comprises a single species, Olettamus alba, described as endemic to coastal dune ecosystems in the southern archipelago of Pelagia. In the fictional classification, Olettamus is placed in the family Olettamaceae, within the order Lamiales.

Olettamus alba is a perennial herb 15–40 cm tall. Stems are slender and often branched. Leaves are opposite, simple, oval to lanceolate, 2–6 cm long, with fine serrations. The inflorescence is a loose panicle bearing small, five-petaled white flowers. The corolla is tubular at the base with a flared limb. After flowering, the plant develops a dry capsule containing several seeds.

It grows in well-drained sandy soils of coastal dunes, from sea level to about 40 meters elevation. It tolerates salt spray and short drought periods. Pollination is primarily by hoverflies and solitary bees; seed dispersal is primarily wind-driven, aided by light, winged seeds.

Endemic to Pelagia's southern archipelago; in the fictional ecosystem it forms small, scattered populations. Habitat loss from coastal development and invasive plants are cited as threats; no formal conservation status exists in this fictional context.

The genus name Olettamus is a constructed designation; the species epithet alba refers to the white corolla.
