This fourth Coachwhip anthology of weird botanical and fungal entities collects 21 stories with menacing flowers from the darkest corners of the globe, invasive seeds from outer space, botanical experiments gone awry, and expeditions encountering mythical green horrors. From the uncanny nature of our vast forests and jungles to the scientific manipulation of vegetational genes, the world of plants and fungi offers a vast wellspring of inspiration for writers of speculative fiction, and these anthologies have shown the many strange and different ideas that take root under cover of darkness.
