1918] Long,— Eragrostis peregrina 175 
duplicate material in actuality (from a joint trip by Small and 
Heller) of the specimen cited by Professor Wiegand. 
Search at the University of Pennsylvania was rewarded by an old 
specimen from Fairmount Park, Philadelphia, from the Herbarium 
of Isaac Burk — not dated but probably about the 60’s.1 
Professor Wiegand’s interest was obtained in this Philadelphia 
‘material and through his kindness it has received his verifying determi- 
nations. 
During June it was possible to identify with certainty an Eragrostis 
that for several seasons had been noted regularly appearing in the 
roadside gutters near my home — and thus at once begin a fuller 
acquaintance with Eragrostis peregrina almost at my own door. Here 
in Ashbourne and Elkins Park (contiguous suburbs nine miles north of 
Philadelphia) the plant occurs at quite a number of stations, invariably 
between the bricks used in the gutter construction on some of the 
newer and more improved roads. At some places where there are 
as yet no houses and the gutters are not kept weeded, it has become 
locally abundant and quite conspicuous, but, though well distributed, 
in general the street cleaning reduces its occurrence to small and 
scattered colonies. Immediately south of Elkins Park station is a 
large colony of many plants growing on the railroad ballast beside the 
Philadelphia & Reading tracks. Along a foot-path within the rail- 
road right-of-way it is noticeable here and there in small colonies. 
At Fort Washington, about sixteen miles out of Philadelphia along 
the Reading, the 1908 collection was verified. The plant appeared 
to be rather rare along the roadside in the village. -Careful exploration 
of the main tracks and several sidings by the railroad station failed to 
reveal its presence in these habitats. 
During July an opportunity occurred of spending a day botanizing 
in Bucks County, Pennsylvania with Dr. C. D. Fretz —a name 
especially associated with the plants of that county. My travelling 
to join him led me still further north on the Philadelphia & Read- 
ing. While waiting for a connecting train at Lansdale, I found 
E. peregrina to be locally abundant along the Bethlehem Branch of 
1 Here in the University Herbarium was also found among Mr. Robert Le Boutillier’s Japanese 
Plants characteristic material of Eragrostis peregrina. It will be recalled that Professor Wiegand 
notes that its native country is not yet known. The general region of the islands of Japan 
being the only area in the at present known distribution of the species where apparently the 
plant is not definitely recorded as introduced, one naturally wonders whether it might possibly 
be indigenous there.
