A genus of Gram-negative bacteria which is not assigned to any taxonomic family. It is similar to Caulobacter in its life cycle, but differs in that the stalk occurs eccentrically at one pole or on one side of the cell, and does not function in attachment. Cells adhere to a substrate by adhesive material near one end of the cell. It is found in habitats similar to those of Caulobacter.
