74.‘ Pretz: Ftora or LEHIGH Counry, PENNSYLVANIA 
The species is the form typical for the region, described as 
E. hyemale affine (Engelm.) A. A. Eaton. 
EQUISETUM SYLVATICUM L. 
Infrequent in the bogs on the South Mountains, where it is 
rare in fruit. Very abundant and freely fruiting in an open marsh 
southeast of the Bake-oven Knob on the Kittatinny Range (April 
30, 1910, 2357) and presumably present elsewhere in the vicinity 
of this range. Sterile plants 5.3 dm. high represent average luxu- 
riance. Collected in fruit on April 30. Herbaceous, withering 
early. 
LyYCoOPODIUM CLAVATUM L. 
In the general vicinity of the bog 1 mile south by southwest 
of Mountainville, on the South Mountains, there are three places 
where this species has been found (October 5, 1907, 1007), and it 
has also been collected 1 mile south by southeast of Mountainville 
(March 6, 1910; November 12, I910, 3102). It occurs sparingly 
near a moist open area in a quarrylike exposure of Hardyston 
sandstone, on the spur of the South Mountains along the Lehigh 
River, °4 mile northeast of Strassburg (May 31, 1908; October 29 
1910, 3049). It is nowhere abundant and has not been found 
in fruit. Evergreen. 
This species is not infrequent, often abundant and usually well 
fruited, in the mountains near Mauch Chunk in Carbon County and 
near White Haven in Luzerne County, to the northwest, but has 
been seen nowhere in Lehigh County growing in these apparently 
normal conditions. Though the species has been collected well to 
the southeast of the mountains, in Pennsylvania, it can be said to be 
an infrequent or even rare species in Lehigh County. 
LYCOPODIUM COMPLANATUM L. 
General throughout, but local in its occurrence and frequently 
abundant. Growing in open and shaded situations and on all 
soils and formations. Less frequently fruiting but usually more 
luxuriant in shade than in the open. Fruits late in August. 
Evergreen. 
The species is the form typical for the region, described as 
var. flabelliforme Fernald.
