1911]  Thompson,— Botanizing in central Connecticut 79 
est find during the past season, as it is very rare in this state and we 
had seen it growing only once before — in Maine. 
Rhododendron canadense (L.) BSP. has also increased amazingly 
since the destruction of the pines and now forms little thickets on the 
higher land bordering the marsh. Its being so much in evidence 
suggests a new name for this region — Rhodora Swamp! 
As we emerge into the pasture lands we find a few small bogs, and 
on the edge of one of these 
Lycopodium inundatum L. grows in rather a stunted fashion in one 
small colony. 
On our way to North Cromwell Station, the swamp left well 
behind, we pass two or three small ponds and extract from them 
Marsilea quadrifolia L. possibly introduced from Bantam Lake, at 
one time its only known habitat in America. 
Ceratophyllum and Elodea neárly choked one pond with their tangle, 
the former with its finely dissected leaves, and the latter dotting the 
surface of the water with its tiny blossoms not much larger than 
pin-heads. 
In a neighboring pasture one of the party discovered many fine 
specimens of that elusive but not rare little fern Ophioglossum vul- 
gatum L. 
Referring to the Catalogue of the Flowering Plants and Ferns of 
Connecticut, we find of the species mentioned in these notes, one 
(Carex subulata) has not been recorded; thirteen are set down as 
“rare,” and several others as “occasional” or “local.” Considering 
that most of the choicest specimens were found in a spot of but a 
comparatively few rods in radius, it seems as if Pine Swamp — or as 
we would like to call it, Rhodora Swamp — in Central Connecticut 
were worthy of more than a passing notice.
