C. 
PLANTS NOT BEFORE REPORTED. | 
Ipomeea 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, Avt. 
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, Hook. 
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 / ovina, 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 fallaz, 
which is common in Europe. 
Molinia cerulea, Mench. 
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. J. F. Allen. 
Tolypella fimbriata, Allen. 
Lake Ontario. Allen.
