NEW STATIONS FOR MAINE PLANTS.—In July, 1903, a few plants 
of a peculiar ZZeraciuzm were collected by the writer near Skowhegan, 
Maine, under the impression that they were ZZ. praealtum, L. Speci- 
mens have since been determined at the Gray Herbarium as ZZera- 
cium floribundum, Wimm. & Grab. This species has previously been 
collected by Dr. Kennedy at Cutler, Me., (RHODORA, IV, 25.) and at 
St. John and Bathurst, N. B., by Mr. Williams and Mr. Fernald. 
Later in the summer the writer and Mr. C. H. Knowlton found 
several specimens of Polygonum exsertum, Small, growing at the 
edge of salt marshes at Pine Point, Scarboro, Me., a station inter- 
mediate between that of Mr. Bicknell at York, Me., and that of 
Messrs. Williams and Fernald at Bathurst, N. B. 
Scirpus rubrotinctus confertus, Fernald, is in my herbarium from 
Cumberland and Farmington, Me., localities which extend the range 
in both directions from the station at Greene, Me., mentioned by Mr. 
Fernald (RHopoRa, II, 21.) in his description of the variety.—

THE GENUS TRISETUM IN ANDOVER, MASSACHUSETTS.— On June 8, 
1903, while collecting ina boggy meadow in Andover, Massachu- 
setts, in which were growing Salix myrtilloides, Poterium Canadense, 
Carex exilis, and other plants of interest, I noticed a strange grass 
and gathered a few specimens of it. These were later identified for 
me at the Gray Herbarium as Zyisetum palustre, Torr. This seems 
to be an unusually northern station for this species which is said by 
the Sixth Edition of Gray’s Manual to grow from southern New York 
to Illinois and southward. I have seen specimens from Norwood, 
Massachusetts, and that vicinity; but it is possible that Andover is 
at present its northern known limit. 
On September 19, of this same year, I visited the rocky banks of the 
Merrimac River in the northwestern part of Andover. Here grow 
many species not abundant in this section of the State (e. g. Acer 
Pennsylvanicum, Kalmia latifolia, Campanula rotundifolia), and here, 
in the clefts of steep ledges, I found the other of the two species of 
Trisetum mentioned in Gray's Manual — Z»zsetum subspicatum, 
Beauv., var. mo//e, Gray. On account of the lateness of the season 
the plants were in poor shape for collecting but were still perfectly 
recognizable. This species the Manual describes as found from
