Species Description:
A small, very variable, perennial grass-like native plant with stems somewhat swollen at their bases; sometimes the stems flop over and root at the nodes. Frequently it is viviparous i.e. the flowers are replaced by tiny shoots.

An aquatic free-floating form (var. fluitans) grows in lakes; it has long weak thread-like stems and leaves and is much branched.

All names: Juncus bulbosus L.; Juncus kochii F.Schultz; Juncus bulbosus sens. lat. L.; Juncus supinus Moench
