PoLYGONATUM LATIFOLIUM Desf. Several plants of this Eurasian 
species grow by the roadside in slight shade, near the Concord River 
in Concord, where they were first noticed by the writer May 24, 1909. 
Since this species with comparatively thick green-tipped perianths is 
commonly cultivated it is possible that the references, in the Report 
on the Flora of the Boston District (RHopoRA x. 130) to P. giganteum 
as “escaped” and “introduced,” belong rather to P. latifolium. 
BERTEROA MUTABILIS (Vent.) DC., a large-fruited species but 
recently recognized in our flora, is in the Club Herbarium from a 
“ roadside " in Dedham, August 22, 1897 (E. F. Williams). Similar 
material in the Gray Herbarium, collected by W. P. Rich, bears the 
data: “roadside, border of cultivated ground." Another Massa- 
chusetts specimen in the Gray Herbarium comes from Hingham, 
September, 1894 (T. T. Bow). 
SISYMBRIUM OFFICINALE (L.) Scop. The typical plant, with pubes- 
cent pods, is in the Club Herbarium from a “dump, West Cambridge, 
Mass., July 10, 1909 (C. A. Weatherby). 
POTENTILLA REPTANS L. has been a weed in the lawn in front of the 
Gray Herbarium in Cambridge for at least ten years, It was first 
noticed in June, 1900, and in spite of resodding and alterations of the 
lawn and terrace still holds its own. 
Geum vRBANUM L. is abundantly established by roadsides and 
borders of fields in the neighborhood of the Botanic Garden in Cam- 
bridge. The earliest evidence of this colony is a specimen in the 
Gray Herbarium collected by Professor L. H. Bailey and labeled 
* Cambridge, Mass., Aug., 1884. Thoroughly established." 
AGRIMONIA MOLLIS (T. & G.) Britton. It is apparently not gen- 
erally known to botanists of eastern Massachusetts that A. mollis 
occurs at Winchester. It was first found by the writer on the wooded 
diorite talus of Horn Pond Mountain, October 14, 1906; and the 
station, where the plant occurs in some abundance with Polygonum 
dumetorum L., has since been regularly visited in September or Oc- 
tober. 
TRIFOLIUM MEDIUM L. is either a much more local plant than is 
ordinarily supposed or it is very rarely collected. As represented 
in the Club Herbarium and the Gray Herbarium, it seems to be 
confined to eastern Massachusetts: “Boston, perhaps introduced?" 
(old specimen without date); “In pascius et pratis siccis (ex Europa 
advenam) ad Danvers” (Wm. Oakes); shady pastures about Salem,
