§$ 351. Notes on the Flora of the Lake Superior Copper Region. 
Probably one of the first things that will strike the eye of the 
botanical observer from the vicinity of New York, on his arrival in 
this region, will be the total absence of so many of our familiar forest 
trees.—-Castanea vesca, 1.., var. Americana, Michx., is not to be found 
at all. ‘The genus Quercus is not nearly so plentifully represented as 
with us and Carya is a rarity. 
The mass of the forest is made up of Adies Canadensis, Michx., 
Abies balsamea, Marsh., Pinus resinosa, Ait., Betula papyracea, Ait., 
and a thick undergrow th of Ostrya Virginica, Willd., Corylus ros-— 
trata, Ait., and Betula lenta, iL. 
One of the most conspicuous objects aus roadsides and the 
borders of woods, during July, isthe Rubus Nutkanus, Mocino, with 
its bunches of pure white flowers. In situations a little more shaded 
may be found Adenocaulon bicolor, Hook. Streptopus amplexifolius, 
DC., Streptopus roseus, Michx., and a carpet of Cornus Canaden- 
sis, L., Linnea berealis, Gronov., and Aitchella repens, 1. 
In the deepest parts of the forests, under the shade of the ever- 
greens, the Fricacee are well represented.—Zpig@a repens, L.; 
Gaultheria procumbens, L.; Pyrola elliptica, Nutt.; P. Chlorantha, 
Swartz.; P. secunda, L.; P. minor, .; Moneses uniflora, Gray; Chi- 
maphila maculata, Pursh,; P. umbellata, Nutt,; and Monotropa uniflo- 
ra, L., growin abundance, especially near or on the old rotten trunks 
of Abies Canadensis that have fallen.-With these latter species 
many of the Orchidacee occur: Habenaria Hookert, Torr.; H. orbi- 
culata, ‘Torr. ; Goodyera repens, R. Br.,; G. pubescens, R. Br.,; G. 
Menziesti, Lindley,; Listera convallaroides, Hook,; Mycrostylis 
ophioglossoides, Nutt,; Liparis Laselii, Richard, and Afplectrum hye- 
male, Nutt.—Among the grasses may be noted Brachyelytrum artsta- 
tum, Beauv,; Calamagrostis Canadensis, Beauv, ; Glyceria Canadensis, 
Trin, ; Poa serotina, Ehrhart, ; Gymnostichum Hystrix, Schreb,; the 
new species, Avena Smithit, T. C. Porter,; Phalarts arundinacea, L., 
and Milium effusum, L. 
Among the Cryptogams we have: Zguisetum limosum, L.; £. 
sylvaticum, L.; £. scirpoides, Michx.; Phegopteris Dryopteris, Fée, ; : 
Aspidium aculeatum, Swartz, var. Braunii, Koch, ; Woodsia glabel- 
Ja, R. Br.; and Lycopodium annotinum, L.; L. clavatum, 1..; L. com- 
planatum, L. Selaginella rupestris, Spreng. occurs in great abund- 
ance on rocks and cliffsin company with Asplentum Trichomanes, L,

352. Diseased Lepidium.—Along the roadsides of West Phila- 
delphia I have lately seen two interesting diseased forms of Lepidi- 
um Virginicum which may be more common than I know. In both 
the stem is much thickened, knotted, and cracked, besides being 
somewhat woody. A little cutting shows that this is the effect of some 
egg-laying insect. One form seems to consist mainly in a shortening 
of all the branches of the herb, thickening up the top until it becomes 
a bush you can hardly see through, and, by bringing the pods to- 
gether, giving the plant an appearance of prodigous fruitfulness. This
