From publisher blurb: The Frontiers of space are a diverse ecosystem. Some worlds are devoid of life entirely. Others are nearly teeming with life forms of all kinds. Many new species of animals have been discovered but nearly as many new plant species have also been. These plants vary from beneficial to an extreme hazard when encountered. These life forms provide food, water and even medicinal value in some cases. On occasion these plants are the only forms of life even encountered on some worlds.
