This is the Manatee Grass, better known 

 in botanical literature, but incorrectly so, 

 as Cymodocea manatorum Ascherson. The 

 plant was first described by Kiitzing in 

 1863 from a specimen collected in the 

 Virgin Islands and apparently mistaken 

 for an alga. It occurs widely along the 

 Florida coasts and westward to Louisiana. 

 It often grows on infratidal sandy bot- 

 toms associated with Thalassia and Diplan- 

 thera, from which genera it is readily dis- 

 tinguished by its terete or semi-terete 

 leaves.
