Rollweed

Rollweed was a type of weed that could be found in the habitable band of the cold and lifeless Outer Rim planet Rystan. When Eye of the Nihil Marchion Ro visited Rystan with the Talortai Nihil Udi Dis in 231 BBY, Ro directed Dis to a patch of barren ground where the Talortai noticed clumps of rollweed tumbling across the wasteland.
