These two species are closely allied but yet possess a quite distinct habit ; 

 A. irriguum is a rigid plant, much more branched and interwoven, with acute 

 leaves more or less obsoletely serrulate ; A . fluviatile is softer, with nearly 

 simple stems and few branches, the leaves more or less obtuse at point and 

 with entire margins ; the capsule also is longer.
