2 



woods along river below Manhattanville. Just in flower, May 

 23, 1879. 



Viola odorata, L. has been rapidly increasing for years over a 

 lawn and along a terrace, where the grass in some places has 

 been entirely crowded out. Last year I found it among rocks in 

 woods a quarter of a naile distant. The fragrance is still retained, 

 and it blooms much earlier than any of our indigenous species, 

 being in flower this season by the middle of March, 



Hypericum prolificum, L, I found this shrub in full flower last 

 August, growing aniong briers, and other shrubbery on the bor- 

 der of a small swamp, near the roadside opposite Jerome Park 

 There were apparently several plants, which, if not indigenous, 

 must have been growing there for some time. 



Lychnis vespertina, Sibth. Common along Broadway, at Kings 

 Bridge. May 16, 1879, just in flower. 



Malva moschata, L. A single plant found growing by the roadside 

 near Woodlawn. 



Linum striatum, Walt. Not uncommon in swampy places. 



Floerkea proserpinacoides, Wild. A small patch grows in the 



same glen with Dentaria laciniata, and close to the latter plant. 

 Just in flower, May 8, 1879. 



Euonymus Americanus, L. Not uncommoiu Found at a number 



- of places ; both varieties occur. In fresh flower, June 8, 1879. 

 Staphylea trifolia, L, Rare ; in swamp about i| mile from river. 

 Desmodium acuminatum, DC. Common ; flowers about July 4th. 

 Robinia viscosa, Vent. I found a single tree of this species, near 



an old barn, by a wall in an upland pasture. June i, 1879, '^^ ^^"^^ 



in full flower. 

 Agrimonia parviflora, Ait. Uncommon; Have found it only in 



one spot, 

 Geum Strictum, Ait. Sparingly in swamp' along Broadway; also at 



Sins Sinij. 

 Rubus odoratus, L. Not imcommon along river. Just in full 



blossom, June 4, 1879. 

 R. Strigosus, Mchx. Found sparingly at several places where it had 



probably escaped, though unquestionably indigenous in woods 



below Inwood, and perhaps atone other locality near Riverdale. 



Philadelphus (coronarius7)._ Seems to be fully established about 



the borders of a small swamp, across the road from Jerome Park. 

 Here, on June 25th last, I met with a number of shrubs in full 

 blossom growing among clumps of shrubbery in different parts 

 of the swamp, some of which were only accessible by wading. 

 Lythrum Salicaria, L. Several plants found in border of thickest in 

 field, east of the R. R., between Fordham and Williams Bridire. 

 In full flower, July 22, 1878. 



Zizia integerrima, DC. Grows sparingly on wooded slope to th 

 river just beyond Riverdale. Pods almost mature, June 17, 1879. 



Aralia Spinosa, L. Several of these plants, growing with Sywphori^ 

 carpus, among cluster of trees in deserted orchard; also at one 

 spot on retired road east of Van Courtland Lake 



Lonicera sempervirens, Ait. Climbing high on a single tree in a 



-^
