(July 5), become detached from the plants, but were seen floating 
and cast up on the shore; it had not yet come into flower. Ly- 
copodium inundatum, L., occurs in wet sand on the shore; the 
plant regarded by Professor Tuckerman as var. Bigelovii of this 
species, is very plentiful in sandy bogs in eastern New Jersey, 
and differs from the northern and European plant mainly in its 
greater size; Viburnum nudum, L., was collected near by, and its 
var. cassinoides, Gray—for I cannot regard it as a species—grows 
at Lake Nascia near High Point. V. nudum is common in coast 
swamps. 
Aster linariifolius is abundant all along the mountains, as in 
the sandy coast plains, while the almost impassable thickets of 
Quercus ilicifolia, Wang., make traveling difficult and often pain- 
ful. The resemblance to the pine barren flora is also markedly 
apparent in the great abundance of Ericacee. Gaylussacta 
resinosa, Torrey & Gray, G. frondosa, Torrey & Gray, and 
Vaccinium vacillans, Sol., are all common to both regions and 
equally very abundant, while Epigea repens, L., Gaultheria pro- 
cumbens, L., whose habitat is not always ‘cool, damp woods,” 
Cassandra calyculata, Don., and Rhododendron viscosum, Torrey, 
occur as well. 
_ The floral resemblance here traced bears no relation to the 
geological age of the two regions, the coast plains being late 
Tertiary or Quaternary, the mountains Silurian. But there is 
another range of mountains parallel to the Kittatinnys in New 
Jersey and southern New York, whose flora has many species in 
common with that of the latter. I refer to the ridges of the 
Green Pond System, known at Greenwood Lake as the Bearfort 
and Bellvale Mountains and in New York as the Skunnemunk. 
Here Quercus ilicifolia, the Blueberries and Huckleberries are 
very abundant; Solidago puberula, Tephrosia, Lespedeza hirta, 
Arctostaphylos Uva-Ursi, Aster linariifolius and other sand 
plants. occur. The rock is a silicious conglomerate much 
resembling that of the Kittatinny, and was supposed by Mather, 
while prosecuting the Geological Survey of New York, to be of 
the same age, though his observations did not fully demonstrate 
the fact. Others have regarded these Green Pond Mountain 
conglomerates to be of several different ages, ranging from Pots-
