HALORAGE^. 



MYRIOPHYLLUM, Vaill. WATER-MILFOIL. 



M. ambiguum, Nutt., the type form and var. capillaceum, Gray. 

 Both are abundant in Rotten Pumpkin and Paddock Ponds. 

 Morong. 



(Note by Mr. Morong. I do not believe that var. natans, 

 Gray, or the type, if that variety is to be considered the type, 

 and var. capillaceum, Gray, can be kept distinct, for in both 

 these ponds the plant is at first var. capillaceum while im- 

 mersed, but very soon it gets its head above water, and im- 

 mediately forms pectinate leaves, that is, becomes the type, 

 as described in Gray's Manual. I have plenty of specimens 

 in both conditions which grew together.)
