1919] Pretz,— Trisetum spicatum in Pennsylvania 131 
be mentioned to show the high percentage of northern types found 
in the general association of this series of slopes which, paralleling 
as they do the course of the Lehigh river, face either north, northeast 
or northwest. It need not be surprising to find a plant of such a 
general northern range as Trisetum spicatum occurring with this 
type of association. 
As far as the writer knows Trisetum spicatum has not previously 
been collected or reported as occurring between New York and North 
Carolina. Upon inquiry by Mr. Bayard Long, Prof. M. L. Fernald 
in a reply — kindly furnished to the writer by Mr. Long — has 
written, “ Trisetum spicatum, var. molle! we do not have from Penn- 
sylvania but here are the records from New York and from North 
Carolina; banks of Black River, Watertown, New York, Crawe, 
William -Boott, et al.; Little Falls, Herkimer County, A. Gray; Roan 
Mt., No. Carolina, Buckley, Scribner. It must be somewhere along 
the way between the Mohawk Valley and North Carolina." In 
reply to an inquiry concerning any additional records of New York 
and southward that may have come to his attention, Prof. A. S. 
Hitcheock has kindly furnished the following records from the col- 
lections at Washington; Lyons Falls, Lewis Co., Haberer 3062; 
Jefferson Co., Sartwell; Ausable Chasm, Knowlton in 1883; Oneida 
Lake, Lenox, Madison Co., Haberer 3276; Trenton Falls, Herkimer 
Co., Haberer 1292 — all in New York. In reply to a similar inquiry 
of the New York Botanical Garden, Dr. J. K. Small has kindly 
furnished in addition to the first mentioned above the following 
records from the collections there; near Montgomery, Orange County, 
New York, Wm. Crabtree; Greece, Monroe County, New York, Dr. 
Bradley. The records thus made available through inquiry have 
shown no known stations for the species south of New York state 
excepting that of the North Carolina station. 
It may be interesting to observe that all excepting one of the sta- 
tions recorded for New York are scattered north of a line drawn 
centrally across the State at about 43° latitude and that this one 
exception, the station for Orange county, is quite well away from 
the rest and not greatly distant from the boundary of New Jersey. 
This Orange county, New York, station would seem to be more nearly

regards as Triselum spicatum var. molle which represents the most southern of the several 
varieties of Trisetum spicatum distinguished by him.
