978. N. marina, L. (JV. major, of Man., p. 483.) 



The typical form is frequent in shallow water near Canoga 

 Marshes and near Cayuga Bridge, west side of lake. July. 



979. N. marina, L. var. gracilis, Morong, {Bot. Gazette, vol. 10. p. 



254-) 



Off Canoga Marshes. Our specimens have the long stems and in- 

 ternodes and long slender leaves of the Florida form from which the 

 original description was drawn ; viz. "No. 2705" of Curtiss' " North 

 Amer. Plants." They however lack the purple color of the latter 

 specimens. 



980. N. marina, L. var. recurvata, n. var. 



In the shallow water of Black L. Cayuga Marshes. 1880. Stems 

 stoutish, short, 5-12 cm. inclining to be dichotomously branched, 

 spreading and recurved. Leaves purplish, (the olive-purple of 

 Chondrus, ) recurved usually, the teeth large and prominent. At the 

 base of the leaf the sheath around the fruit shows a projecting 

 tooth on each side, while in the typical form and var. gracilis, the 

 sheath is rounded. Seeds, like the type, except reticulations are 

 often more pronounced. Mr. Morong has most kindly examined 

 the varieties described by Braun, to which I had not access, and 

 writes that there is nothing corresponding to var. recurvata among 

 them. 



981. N. flexilis, Rostkov. (H. and C.) 

 In all our lakes and quiet ponds. July. 



Either mossy and 2-3 cm., or slender and % meter or more in
