Itea ange Alnus serrulata. In Griscom’s swamp between Tuckahoe and Great Egg Harbor 
rivers occur Fagus americana, iisdenaren tulipifera, Quercus bicolor, Q. phellos, Q. alba, Q. prinus, 
lex opaca, en Nyssa, Pinus rigida and Magnolia. It is remarkable that in this swamp one 
finds Quercus bicolor the only place where it grows in South Jersey and also Fagus and Lirio- 
dendron separated from the broad leaved forest by a broad stretch of pine land. Similar swamps, 
according to Harper, occur in Long Island. 
Grass Slough Formation. There are many acres of grassgrown land in 
New Jersey, which approach the “savanna”. This so called savanna consists 
of sloughs covered with a variety of grasses associated with Aiörscus moscheu- 
tos, Decadon verticillata, Tofieldia, Narthecium, while knolls or ridges are 
ER by Pinus rigida with Xerophyllum asphodeloides. The sloughs are 
underlaid near the surface by a layer of bog-iron ore and are fringed by 
boreal plant: Lyonia (Chamaedaphne) calyculata with Vaccinium corymbosum. 
— There are in these territories also cranberry bogs, forming a Cranberry 
Bog Formation proper; the basis of these bogs is sphagnum moss of 
several species, and they may occupy depressions of surface, or they may 
fringe the banks of some fresh water stream. The bog is too wet for trees 
to grow, but we find characteristic species in it, such as Vaccinium macro- 
carpon, which forms dense tangles of growth on its surface, Sarracenia, Lach- 
nanthes tinctoria, Lophiola aurea, Pogonia (2 spec.), Calopogon, Arethusa, 
Drosera (3 spec.), Utricularia clandestina, and near the margins of the bog 
Helonias bullata. 
Pond Formation. This includes both floating amphibious and pond margin 
plants. — (Nymphaea Association): The water surface of the pond is co- 
vered either in whole or part by Nymphaea (Castalia) odorata, Nelumbo lutea 
(rare), Nuphar (Nymphaea) advena, Brasenia peltata (= B. purpurea), Limnan- 
themum lacunosum and Orontium aquaticum. In the water inside of the 
floating aquatics is found ‘the Typha-Sagittaria Association, together 
with Peltandra virginica in the shallower water and Pontederia cordata, Erio- 
caulon, Scirpus subterminalis and two or three species of Xyris, floating 
species of Urricularia: in thick tangled masses. 
The vegetation of Watering Place Pond, according to Saunders ?), is characterized by Nymphaea 
odorata and several ee islands of sphagnum supporting Lyon calyculata and in the shallo- 
west water Carex Walteriana, Woodwardia virginica, while in sphagnum-lined margin (eircum- 
area) grow Pogonia ee Calopogon pulchellus, Drosera filiformis, D. intermedia, 
Polygala Nuttallii, P. Iutea, Seen strieta, Proserpinaca pectinata, Hypoxis erecta and the 
shrubs Azalea viscosa, Vaccinium corymbosum. 
Mention should be made u the grasses of the ee Br which abound in the pine 
barrens: Andropogon, Uniola, Triodia (Triplasis), Stipa, Panicum, Glyceria, Cenchrus and the 
following characteristic species not mentioned before: u cristata, H. ciliaris, Calopogon 
pulchellus, Tephrosia virginiana, Lespedeza hirta, L. repens, L. angustifolia, Polygala cruciata, 
P. brevifolia, P. incarnata, P. mariana, P. Nuttallii, P. polygama, Ascyrum stans, Oenothera sinuata, 
Bartonia tenella, Sclerolepis verticillata covering old ditch bottoms, Eupatorium rotundifolium, E. 
album, E. hyssopifolium, Solidago puberula.
