is able to overcome the possibly adverse influences of surroundings. 

 Of the species of PotentiUa, some of which are rather abundant, Foten- 

 tilla paradoxa, now known as supina, is rare, but is given by Gray as 

 found in this locality. It seems rather shy of civilization, having 

 disappeared from former stations, but is still found tolerably abundant 

 somewhat nearer to Braddock's Bay. Of the water-milfoil family, we 

 find Myriophyllum spicaium, growing in water of some depth. 



Nescea verticillata is an interesting member of our marsh flora, 

 forming a good illustration for study of the transformation of 

 underground stems to the varying needs of plants situated where the 

 environments of water and land are fluctuating. 



Of the Polygonums, many of which are water-loving plants, there 

 are seven species and varieties. 



Utricidaria vulgaris is common. Scrophiilaria nodosa, formerly 

 found, has, I think, entirely disappeared. Our beautiful Convolvulus 

 sepium luxuriates not only in the native marshy tract, but even makes 

 beautiful the track of the railway. 



Euphorbia polygonif alia is a denizen of the sands, but has never 

 been abundant. Of the Aracece we have the common Acorus calamus 

 or sweet flag. Peltandra Virginica, I have found but once and now 

 that has disappeared. Most of the water plants found in other 

 localities are also found here, but of these most interest attaches to 

 the Juncacece, of which there are nine of the species /uncus. 



Of the Cyperacecc, or sedge family, there are four species of 

 Cyperus, seven of Elcocharis, four of Scirpus, and sixteen of Carex. The 

 xdiXt Dulichium spathaceum has also been found. Eriophoruin cyperi- 

 tium is quite abundant. 



The Gratninece, or grass family, has some very interesting mem- 

 bers. Among these are the stately Zizania, with its distinct but not 

 widely separated panicles of sterile and fertile flowe'rs, and the pecu- 

 liar Leersias. 



Sporobolus cryptandrus has, I think, disappeared. Calamagrostis 

 Canadensis, the beautiful blue-joint grass, which has thriven upon the 

 meadows bordering Long Pond, cannot, it is to be feared, survive the 

 present conditions. Amniophila arundinacea, said to be found on sandy 

 sea beaches from New Jersey to Maine, has evidently found that the 

 general conditions of the sandy banks bordering our great lakes are 

 not adverse to its growth ; while it has evidently a utilitarian function 

 in preventing the drifting of the sand in inconvenient locations by 

 means of its root masses. The spikes of this grass are not dissimilar
