1903] VEGETATION OF THE BAY OF FUNDY MARSHES 431 
of the drainage furrows, and the lower ground, where, especially 
on poor marsh, it often replaces entirely the other two and 
becomes the dominant form. Along the roads and in places 
somewhat salt, it is much dwarfed. It is one of the first forms 
to come upon the reclaimed marsh, following after the members 
of the Salicornetum and Staticetum. 
Vegetation-form and adaptations not especially studied; evi- 
dently more halophilous and hydrophilous than the preceding. 
TRIFOLIUM PRATENSE L. Red clover—Occurs as a character- 
istic companion with timothy, under whose shade it thrives every- 
where on the best marsh. It varies greatly in quantity in 
different years, sometimes being extremely abundant (locally 
“clover-years’’), and sometimes being nearly wanting, perhaps 
because it is killed by some winters and requires two years to 
reach full maturity. 
Vegetation-form and adaptations not specially studied, but 
its power of fixing nitrogen comes here into account, and pos- 
sibly some relation of a remotely symbiotic sort exists between 
itand the timothy. It is immediately killed by salt water. 
TRIFOLIUM HyBRIDUM L., alsike, and T. REPENS L., white 
Clover, also occur, but less abundantly. The two former are 
introduced from Europe, but the latter is native. 
CHRYSANTHEMUM LEuUCcANTHEMUM L. Bulls-eye daisy.—Abun- 
dant in places and somewhat gregarious, and in other places 
wanting. Apparently it cannot compete with the timothy and 
couch on the best places but comes in where conditions are less 
perfect for those two forms. Not native, but from Europe. 
Other secondary forms of minor importaace are: 
Alopecurus pratensis L., bastard timothy or Durgin timothy. lesan 
abundant in places, and an injury to the hay-fields through its early ripening. 
Calamagrostis Canadensis Beauv., blue-joint, occurs in occasional patches, 
but belongs rather with the hydrophytic associations. 
Poa pratensis L. Occasional. 
Lolium temulentum L. 
Danthonia spicata Beauv. 
Agrostis scabra Willd. [A. hyemalis (Walt.) B.S. P.] 
Lathyrus palustris L. Rather common in spots on good marsh. 
Ranunculus acris L. Buttercup. In patches on poorer marsh, not 
abundant.
