8 
miles, east or west, they are more frequently met with. In Chau- 
tauqua, Cattaraugus and Wyoming Counties they are abundant and 
sometimes of large dimensicns. But the most extensive of those 
found east of Niagara River occur near the boundary line between 
Genesee and Orleans Counties, and have proved of peculiar interest. 
At Black Creek, in Canada, near where it enters Niagara River, a 
sphagnous swamp occurs, said to extend westward to Marshville, a 
distance of twenty-five miles. This, beyond question, is the larg- 
est one in our neighborhood. Along the lake shore, east of Point 
Abino, a small swamp of sphagnum is found which affords the near- 
est station of Sarracenia purpurea. While all these bogs present 
the same general characteristics, yet in the plants which they 
nourish there is considerable diversity. Scheuzeria palustris has 
been found in one at Hanover, Chautauqua County, and not else- 
where. MMucrostylis monophjllos and Stellaria borealis seem to oc- 
cur only in a piece of wooded spagnum at Machias. Andromeda 
polifolia has been collected in an open bog at the same place, and 
in the one at Black Creek, but not elsewhere. Zontcera oblongt- 
folia occurs in a marsh at Alabama, in Genesee County; and the 
marsh at Bergen, in the same county, alone, has yielded us Cy- 
prepedium candidum and Calypso borealis :—of the latter, a solitary 
specimen. Cypripedium arietinum, diligently sought for in all these 
localities, has not yet been noticed. 
That portion of the city which lies east of Delaware Street and 
north of Scajauquady’s Creek, offers to the botanist a field of no 
little attraction. It early acquired the name of “Buffalo Plains.” 
Here, throughout an extensive area, the corniferous limestone, 
occupying a position almost horizontal, approaches very near the 
surface. In places, the rock remains uncovered. But, notwith- 
standing the fact that the soil is very shallow, the region was 
once well-wooded; and it is still the home of some most inter- 
esting plants, rarely seen in other portions of our district. Among 
them may be named Ranunculus fascicularis, Arabis perfolita, Viola 
palmata, Viola tenella, Ceanothus Americana, Staphylea trifolia, Saxt- 
fraga Virginiensis, Vaccineum stamineum, Pentstemon pubescens, [po- 
mea pandurata, Frasera Carolinensis, Gentiana puberula, Asclepias tu- 
berosa, and Scirpus Clintonit. Its Sylva, also, has its peculiarities. 
Here, alone, we have met Quercus Muhlenbergit, Q. prinoides and
