Muhlenbergia umbrosa Scribn. 

 Low wet woods, Bergen swamp. H. D. House, August 23, 19 18. 

 Collections in the state herbarium indicate that this grass is not rare 

 north of the Hudson highlands. 



Sporobolus vaginiflorus (Torrey) Wood 

 Open marly bog of Bergen swamp. H. D. House, .August 23, 1918 



Lycopus asper Greene 



Shady places, Bergen swamp. H. D. House, August 14, 19 16. 



The finding of this species, a native of the middle and western 

 states, in Bergen swamp, is not surprising in view of numerous other 

 western plants found in Bergen swamp and other localities in western 

 New York. 



The chief characteristics of this species are the rather stout stems 

 perennial by stolons at the base, strongly pubescent toward the 

 summit, puberulent or glabrate below and on the leaves. Leaf -blades 

 oblong-lanceolate, closely sessile, sharply serrate with rather distant, 

 ascending, low teeth; bracts acuminate-subulate, some of them often 

 as long as the flowers; calyx somewhat two-lipped, the upper lip 

 with three subulate-lanceolate teeth, the lower lip with two somewhat 

 shorter and merely acute teeth; corolla white and somewhat longer 

 than the calyx; nutlets shorter than the calyx, but as long or longer 

 than the calyx- tube, brown and puberulent. 



Nabalus trifoliatus Cass. 



Chiefly in the shady portions of Bergen swamp. H. D. House, 

 August 23, 19 1 8. Nabalus serpentaria (Pursh) Hook was also 

 observed as a frequent species here, and occasionally both were to be 

 found on the borders of and even on the firmer portions of the marly 

 bog in the center of the swamp. 



Solidago uliginosa Nutt. 



Common in Bergen swamp. H. D. House, August 28, 1918. 

 Rather variable, one form being weak and slender, another form 

 possessing leaves rather thin and narrow. 



Other golden-rods common in Bergen swamp and observed on this 

 date 'are Solidago patula, Solidago rugosa, Solid- 

 ago serotina gigantea, Solidago ohioensis, 

 and Solidago houghtonii.
