Lepidium Virginicum, Oxatis striata, Amaranthus albus and A. spi- 
nosus, Eleusine Indica, Digitaria sanguinalis, Oplismenus Crus Galli, 
Setaria viridis, S. glauca, Paspalum setaceum ?, Abutilon avicenne, 
Portulacca oleracea, and Phytolaca decandra. Most of. them are 
thought to be introduced intruders, as are certainly a host of 
common English weeds of cultivated ground, which have now ob- 
tained footing in most parts of the Union, and seem to be as much 
t home as in their native soil: such are, Trifolium repens, Linaria 
vulgaris, Stellaria media, Carduus arvensis (Canada Thistle), and 
C. lanceolatus, Chenopodium album, Arctium Lappa, Capsella 
bursa-pastoris, with many others. 
During this my first stay at New York, I made several excur- 
sions into the neighbourhood, especially to Hoboken (a village on 
the New Jersey shore), and along the banks of the noble Hudson 
or North River, which on that side towards Weehawken presents 
a succession of bold, rocky, and finely wooded heights. On one 
of these occasions I was accompanied by — Brown Esq., Secre- 
tary to the Lyceum of Natural History of New York, an excellent 
local botanist, who kindly pointed out to me the rarer species of this 
rich locality. The soil at Hoboken is sandy, as is that of a great 
part of the state of New Jersey. Betwixt the shore and village, 
and a line of low wooded hills, are brackish, marshy flats, densely 
covered with a variety of paludal plants, especially Cyperaceæ and 
Grasses. In these marshes, amongst numberless other things, I 
remarked Iva frutescens, Erechtites (Senecio) hieracifolia, Eupa- 
torium purpureum, Verbena hastata and urticefolia, (the tall — 4 
stems of the former, with dense panicles of blue flowers, rose con- — 
spicuously above the surrounding swamp), Veronica præalla, Im 
patiens fulva, and I. pallida, Penthorum sedoides, Elodea Virgi- —— 
nica, Rosa Carolina, (the deep blush of whose blossoms ornaments 
the low grounds in most parts of the country), Panicum hispidum, — T 
Carex tentaculata, with other undetermined species, Leersia ory- — ; 
zoides, Mimulus alatus, Lilium superbnm, Hibiscus palustris or ta 
Moscheutus? Ludwigia macrocarpa, (from its singular cubic capsule — 
called Seed-box) Isnardia palustris, Myrica cerifera, Cassia Mori — 
landica, Sambucus nigra (var.? Canadensis) Polygonum sagittatum -
