\ aUcstierid siiiralis L. Ciillod Eel-grnss. Said to be the wild celery of 

 Chesapeake Bay. The plants bearing pistillate flowers grow in shal- 

 low water. I saw none deeper than two or three feet. The male plant 

 was most abundant in water from eight to 18 feet deep. We found 

 it as deep as 24 feet. The pistillate flower is carried to the surface 

 of the water by a long thread-like scape. After fertilization the scape 

 forms a spiral of several coils, drawing the ovary several inches under 

 water, where the seeds ripen. The staminate flower has a short 

 peduncle. When the pollen is mature, the flower separates from the 

 plant and rises to the surface. The pollen, escaping from the anther, 

 floats away to the pistillate flowers. The buds or stolons formed 

 in the fall, on the male plant, are highly prized by mud hens and 

 ducks as food. They will dive 10 or 15 feet for it. The shores are 

 often thickly covered with the leaves they break off while getting these 

 dainty bits of food.
