1915] Deane,— A Salt Marsh during Reclamation 219 
and along the river border. The plants are vigorous and form fruit 
freely. "These shrubs, undoubtedly, came from seed from the culti- 
vated plants growing along the border of Mt. Auburn Street, one third 
of a mile and more away. The akenes, furnished with long and 
copious pappus, are readily borne by the wind. 
Pluchea camphorata (L.) DC. A good many plants in the southern 
hall, in the middle of the marsh and along ditches. Well developed 
fruit was formed. 
Anaphalis margaritacea (L.) B. & H. A few plants on the western 
portion. 
Gnaphalium polycephalum Michx. Very abundant and vigorous 
over the densely compact grassy areas, including Black Grass, as well 
as in more open soil. 
Z mbrosia artemisiifolia L. Frequent on the west border. 
Xanthium echinatum Murr. Several fruiting plants at the north 
end. 
L'elianthus laetiflorus Pers. Several flowering plants and about 
two dozen young plants at the south end. 
Fidens discoidea (T. & G.) Britton. One or two plants, border of 
ditch, near the river about midway on the marsh. 
Eidens frondosa L. Abundant at mouths of ditches and along the 
river bank; extremely abundant on the west side; plants vigorous. 
Bidens connata Muhl. (Rmuopoma x. 197-200, 1908.) Scattered 
here and there over the marsh, a few very large plants about midway 
on the border of a ditch near the river. 
Bidens cernua L. Scattered throughout along the river bank and 
elsewhere. 
Aehillea Millefolium L. Occasional. 
Tanacetum vulgare L. Several plants at the south end and a few 
scattered throughout. 
Artemisia vulgaris L. Abundant along the marsh border. 
Erechtites hieracifolia (L.) Raf. “I noted this from the side of the 
cemetery and I should say that it covered half of the southern half 
of tie area, besides being extremely abundant in close patches, in the 
northern half. Also scattered here and there." Journal, Aug. 31, 
1912. “Is rapidly discharging its fruit, and, as I walked through the 
dense areas occupied by this plant, the surface of the marsh was 
snow-white with the fallen pappus." Journal, Sept. 25, 1912. The 
dense growth of this plant has nearly killed out the Black Grass,
