The common grape is the frost-grape ( Vitis cordifolid). June- 

 berries or Service-berries (Amelanchier) are abundant and excel- 

 lent, but no opportunity was found for determining the species. 

 A. canadensis and A. Botryapium were observed. Blackberries 

 are collected in some quantity, but are of rather poor quality, 

 and the species were not determined. 



Some of the interesting plants of the sand barrens are Lacinaria 

 cyliudracea (Michx.) Kuntze, L. scariosa (L.) Hill, Nabalus trifo- 

 liatus Cass., with purple flowers, Lonicera glaucescens Rydberg, 

 Polygonellaarticu/ata(L.) Meisner and Hdianthus occidental Rid- 

 dell. Lycopodium sabinaefolium is very abundant and is assur- 

 edly distinct from L. complanatum. Its rhizome is deeply buried, 

 its branchlets stiffly erect, its spikes small and its color of a 

 beautiful blue-gray. 



The cedar swamps are deeply carpeted with sphagnum, in 

 which grow many orchids. In one small spot were collected 

 the following : Cypripcdium acaide Ait., very large and luxuriant, 

 C. reginae Walt., C. hirsutum Mill, Limnorchis hyperborea (L.) 

 Rydb., Lysiclla obtusata (Pursh) Rydb. and Limodorum tuberosum 

 L. With these grew Triglochin maritimum L, of striking 



associated with them in northern bogs. The smaller cranberry 

 was very abundant in the moss, and Calla grew in the streams. 

 All the above were in fruit. While enjoying the beauties of this 

 spot, I could not but think it perfectly feasible to establish such 

 a one in some one of the low spots in our Garden. Probably no 

 other plants of this region are of greater interest than the sub- 

 merged aquatics which cover the bottoms of the lakes and quiet 

 streams. Potamogetons are in great variety. I was particularly 

 interested in P. Richardsonii (A. Bennett) Rydb. (P. perfoliatus 

 Richardsomi A. Bennett), which is certainly distinct from P. per- 

 foliatus L. Sagittaria cuneata Sheldon was collected in Pine Lake. 

 Vallisneria spiralis L. is abundant, and its habit is strikingly dif- 

 ferent from that which it displays in our streams about New York.
