SOME GRASSES NOTEWORTHY IN MASSACHUSETTS.

At Edgartown, Marthas Vineyard, out towards the water tower 
there is a sandy sloping field, less than an acre as I recall it, a good part 
of which is covered by densely growing patches of this European 
grass. When it was first seen there, September 15, 1910, the panicles 
were dry and contracted, but it was easily recognizable as the same 
grass I had of late years collected at several places on Long Island 
and put aside for future study, supposing it to be some introduced 
species of Atra. Recently, at the New, York Botanical Garden, 
specimens were shown to Mr. George V. Nash who recognized it at 
once as this European species, not previously reported from America, 
and pointed out to me the slenderly clavate awns of the flowering 
glumes by which it is readily distinguished from any species of Aira.

Since it has made itself perfectly at home at the places where it has 
become established, and thus promises to take its place more widely 
among our introduced grasses, the facts of its present status should be 
placed on record. 
It was first met with on Long Apel June 27, 1903, growing in 
abundance on sandy levels along the southwestern side of the Hemp- 
stead Reservoir, and about its southern end, and was conspicuous 
from its densely tufted manner of growth, pale whitish green or 
violaceous color, and silvery panicles. On August 5, 1905, it was 
found, also in abundance, growing along the sandy causeway of the 
Ridgewood acqueduct, south of Jamaica, about seven miles to the 
west of the Hempstead locality. Still another station is at Cedar- 
hurst, about five miles distant from each of the others, and nearer
