PLANTS NOT BEFORE REPORTED. 



Ipomoea purpurea, Lam. 



Along railroads and in waste places. West Albany. It is commonly 

 cultivated as an ornamental plant and for the sake of shade. It con- 

 tinues to reproduce itself from year to year and spreads readily by seed. 



Populus dilatata, AiL 



Sandy soil beyond West Albany. This tree, formerly introduced for 

 ornament, produces only staminate flowers with us, and therefore does 

 not propagate itself by seed. But it spreads freely by its roots, and 

 having once obtained a foothold it does not often yield its ground un- 

 less compelled to do so by man. In the station whence our specimens 

 were taken, there is a grove of thrifty young trees at a considerable dis- 

 tance from any dwelling, but they are probably the descendants of trees 

 planted there many years ago, perhaps in front of some dwelling, all 

 traces of which have long since disappeared. 



Listera convallarioides, HooJc. 



Turin, Lewis county. Romeyn B. Hough. The three North Ameri- 

 can species of this genus have now all been found in our State, but they 

 are all rare with us. 



Festuca rubra, L. 



Wet ground. Caroga, Fulton county. July. This was formerly con- 

 sidered a variety of F. ovma, sheep's fescue, but it is now generally 

 classed as a distinct species. It is said to be indigenous about Lake 

 Superior and northward, but has probably been introduced in the 

 locality here mentioned. It was found in a clearing recently made, and 

 could not have occupied the station many years. According to Pro- 

 fessor F. L, Scribner, our specimens correspond to the variety fallax, 

 which is common in Europe. 



Molinia caerulea, Mcench. 



Wet ground. Caroga. July. A grass introduced from Europe, and 

 perhaps not yet fully established here. It was found growing with the 

 preceding species, and with several of our native grasses, and was ap- 

 parently well able to take care of itself. It forms dense tufts, and has 

 an erect, somewhat rigid appearance. 



Tolypella comosa, Allen. 

 Seneca lake. T. F. Allen. 



Tolypella fimbriata, Allen. 

 Lake Ontario. Allen.
