miles, east or west, they are more frequently met with. In Chau- 

 tauqua, Cattaraugus and Wyoming Counties they are abundant and 

 sometimes of large dimensions. 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 Marsh ville, 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. Microstylis mo'nophyllos and Stellaria boreal is 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. Lonicera oblongu 

 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 ol 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 fttscicularis, Arabis perfolita, Viola 

 palmata, Viola ienella, Ceanothus Americana, Staphylea iri folia, Saxi- 

 fraga Virginiensis, Vaccineum siamineutn, Pentstemon pubescens, Ipo- 

 moea pandurata, Frasera ( 'arolinensiSi Gentiana puberula, Asrlepias ///- 

 berosa, and Scirpui Clintonii. Its Sylva, also, has its peculiarities. 

 Here, alone, we have met Quercus Afunlenbergii, (?. pfinoides and
