14G Ilhodora [June 



The evening train into Yarmouth whistled a couple of hours be- 

 fore we had completed the circuit of Trefry's Lake, but so keen were 

 our interest and enjoyment, that last trains were not to he considered, 

 and when we finally got back to our starting point a seven-mile 

 road-walk was between us and Yarmouth. There were a few rem- 

 nants left from lunch and, after passing the village of Arcadia, we 

 left the dusty road and enjoyed our simple arcadian meal while 

 closely scrutinized by the cattle of a roadside pasture. 



Next day, we were more than crowded in putting up our specimens 

 and overhauling the presses and at night we lost Bean, who was 

 obliged to return home. 



The map indicated some small ponds not far west of Hectanooga 

 station and, consequently, on July 31, Long and Lander tried to find 

 them, but not even the oldest inhabitant, whose acquaintance they 

 promptly made, knew of any such ponds and they were forced to 

 content themselves with Hectanooga Lake and the very unsatisfy- 

 ing Little Doucette Lake. These lakes, although not up to our 

 somewhat exacting standard, furnished a few good things: the 

 largest Isoctes of the summer, with bulbous base 4.5 cm. in diameter, 

 the coastal plain Potamogcton Oakcsianns which we had not had, 

 Najas flexilis, also the first of the season, and one of the representa- 

 tives of the complex group passing as Sagittaria graminva; and in 

 the woods, which they reported as rich and unspoiled, were Agri- 

 monia gryposcpala, the northern Pyrola secunda, var. obtusata, and 

 other plants indicating essentially virgin forest. 



White and I, at the same time, had drawn a more prolific area, 

 Salmon or Greenville Lake, where the reconnoitering party of the 

 13th had found Galium tiurtorium. We left the car at the southwest 

 corner of the lake and made our way across a boggy pasture to the 

 shore. At the point where we reached the lake a cold brook enters 

 and in it grows a splendid clump of the tall, perennial smartweed 

 described by Small as Polygonum pundatum, var. robu.sior, a hand- 

 some plant ranging northward from South America but heretofore 

 unknown east of Massachusetts. Subsequently, however, we found 

 it at other stations in Yarmouth County (fig. 13) always character- 

 istic and here as from Massachusetts to South America constantly 

 differing from P. acre (or P. punetatum) in its very stout stems; strong, 

 perennial, woody rootstock with coarse basal offshoots; more approxi-
