taria latijolia), water-plantain (Alisma subcordatum), and the 

 ubiquitous Spirodela polyrhiza (smallest of all known flowering 

 plants), duckweed (Lemna), and cattail {Typha). The sweet- 

 flag {Acorns Calamus) is very common, and a pinweed (Lechea 

 Leggettii) abounds in open woods, while the sticky-flowered 

 Ciiphea petiolata is widely distributed in dry fields. Two species 

 of yellow false-flax (Cathartolinum) and two of partridge-pea 

 {Chamaecrisla) are common, but the presence of Plantago 

 halophila, Melampyrum lineare, Grossularia hirtella, Ribes triste, 

 and Micranthes pennsylvanica comes as a surprise. Three species 

 of Apocynum often grow almost side by side in Washington 

 Valley, from which locality 84 forms of lichens, 52 species of 

 mosses, 55 agarics, and 13 polypores have also been recorded. 



Extremely showy is the tall purple-flowered gayfeather or 

 blazing-star (Liatris spicata). Very noteworthy is the presence 

 of the cranberry-bush ( Viburnum trilobum) and of the purple 

 virgin's bower (Atragene americana). 



Other plants of the region worthy of mention are the common 

 eastern rush {Juncus effusus var. solutus), the northern pitcher 

 plant {Sarracenia purpurea), the swamp-honeysuckle {Azalea 

 viscosa), the round-leaved sundew {Drosera rotundifolia) , the 

 northern prickly-pear {Opuntia compressa), the walking fern 

 {Camptosorus rhizophyllus) , the northern hornbeam {Carpinus 

 caroliniana var. virginiana) , the common American reed {Phrag- 

 miles maximus var. Berlandieri)^ and the sassafras {Sassafras 

 albidum var. molle). 



In a future article the author hopes to compare the northern 

 (glaciated) with the southern (unglaciated) portions of the 

 Watchung Mountains and the eastern ridges (First and Second) 

 with the western ones (Third and Fourth).
