Figure 1. General morphology of Zostera marina. 



Eelgrass leaves are bound together in a sheath attached to an 

 underground rhizome with clusters of roots on each rhizome node. 

 Lateral vegetative or reproductive shoots may originate from within the 

 sheath of the main shoot. The inflorescence on the lateral reproductive 

 shoot contains both male and female flowers. Reproductive shoots may 

 also originate from new seedlings or the main vegetative shoot may 

 develop into a flowering shoot.
