Surata IV was the fourth planet in the Surata planetary system. The atmosphere was capable of supporting humanoid lifeforms.
In 2365, the USS Enterprise-D visited here, where William T. Riker was stung by a thorn teeming with Surata IV microbes which attacked his central nervous system. The vine was predatory, as it deliberately stabbed any warm-blooded creature that happened by it. The plant then absorbed the nutrients from the decaying victim in order to grow and propagate. (TNG: "Shades of Gray")
