Chained Basilliphyta

The chained basilliphyta split from its ancestor, the darwin basilliphyta. It doesn't really split any more, but staying connected by the cell walls, forming chains. A cell at the end of a chain can split a new cell at its side, so that every cell has two neighbors. When not broken by weather or fauna the chains can be up to 20 meters wide. The advantage of that is that the cells can swap nutrients through their cell walls, being a primitive sort of pipeline.
