Galium Aparine, L. ; common. — G. asprellum, Michx. ; common. — 

 G. trifidum, L. ; common; Var. pusillum, with Valeriana syl- 

 vatica at Pulver's Corner.- — G. trirlonun, IVTichx. common. — 

 G. pilosum, Ait. ; common on Stissing Mt. — G. circsezans, 

 Michx. ; common. — G. lanceolatum, Torr., nearly as common as 

 preceding. — G. boreale, L. ; ravines eastward, but extra-limital ; 

 it undoubtedly grows on the Mountain. 



Cephalanthus occidentalis, L. ; common. 



Mitchella repens, L. ; common. 



Houstonia caerulea, L. ; not common ; but abundant in R. Ham's 

 meadows, [Miss Hattie D. JSosticick) ; also near Shekomeko. 



Valerianace^e. 



Valeriana sylvatica, Richards, vid. § 48 and § 56, Vol. VI. ; this 

 rare plant is certainly not scarce about Pine Plains. It is 

 abundant in the following localities: in Mulford Wheeler's 

 peat bog or marsh near Pulver's Corner; Pogonia swamps, 

 near Attlebury; Wappingers Marsh, near base of Stissing Mt. ; 

 Marsh west of Croghan Hill, etc. It embraces a circuit of 

 about twelve miles in diameter, this being the extent thus far 

 of my botanical explorations; hence the plant undoubtedly 

 extends much farther, and very probably will be found in Mas- 

 sachusetts and Connecticut, one of my stations being within 

 three miles of the line of the latter State.
