associated with many of our best known species: Triglochin maritima, 
Elymus arenarius L., Carex norvegica Willd., Polygonum Fowleri 
Robinson, Spergularia canadensis (Pers.) Don, Glaux maritima L., 
var. obtusifolia Fernald, etc. Since all these and many other speties 
with which it grows are abundant on the eastern coast of Maine, it 
is hoped that Scirpus rufus may soon be found in that region. 
S. Smithii Gray and its var. setosus Fernald are often confused in 
herbaria with 5. debilis and are probably more widely distributed 
than at present known. | S. debilis has the achene biconvex, S. Smithii 
plano-convex, one of the faces being distinctly flattened. 
S. sylvaticus L. grows at Hanover, New Hampshire and will prob- 
ably be found on the Vermont side of the Connecticut. 
Scleria. "Тһе species of Scleria are all very local and little known 
in New England. Any new stations for them are of unusual interest. 
They occur chiefly in damp pine-barrens. 
GRAY HERBARIUM. 
FILIPENDULA RUBRA IN MAINE.— Five years ago in June, I observed 
near à road which runs through a meadow near my camp a plant with 
which I was not familiar. In July when it blossomed I determined 
it to be Filipendula rubra (Hill) Robinson and sent a specimen to the 
Gray Herbarium for verification. Mr. Bartlett wrote me that the 
plant was what I thought. He says it is native only in the central 
and southern states though it is commonly cultivated in the East and 
sometimes escapes. ‘There is however none under cultivation in this 
town and the plant must have been introduced by grass seed. Mr. 
Bartlett says it is reported as well established in Vermont and Con- 
necticut but has never-been recorded from Maine. | 
The plant has increased until there is a large clump of it and it 
presents a striking appearance with its stalks of pink blossoms.—
