St. John,— Status of Glyceria Fernaldii 75 
likewise had been determined as Siegesbeckia orientalis L. Here, 
then, was a foreign (Asiatic) species that had persisted for from thirty- 
five years (i. e., since Elihu Hall’s death) to nearly fifty years. But 
what to us seems far more worthy of record is the fact that none of 
the other introduced species were found to have maintained indepen- 
dently a foothold. 
While the manuals do not list Siegesbeckia orientalis for the United 
States, Dr. Robinson states, in a letter accompanying his determina- 
tion, that it has been found a few times before in America; that a 
form of it even was found “some years ago in a hilly bit of dump land 
within a quarter of a mile of the Gray Herbarium” at Cambridge, 
Massachusetts.

THE STATUS OF GLYCERIA FERNALDII. 
HarorD St. JOHN. 
À DETAILED examination of a large amount of material has con- 
vinced the writer that Glyceria pallida (Torr.) Trin., var. Fernaldii 
Hitchc. has abundant and stable characters. It also departs from 
the species with which it has been associated in having a later flowering 
season and a different range. 
These matters are stated below in tabu- 
lar form and should convince the reader, as they have the writer, that 
the plant should be considered as a species.

Anther cylindrical, 1 mm. long. 
Spikelets usually 4-7-flowered, 6-7 
mm. long. °
