matter how it may have originated, is propagating a weakened 
plant in so far as it has its normal amount of chlorophyll reduced. 
The fact thatsome sorts of the self-blanched celery have been 
found more susceptible to blights and decay bears directly upon 
this point. It is a pity that so many of our choicest variegated 
plants blight easily ; it is, however, natural that they should do 
so. Even a fungus parasite will take the line of least resistance. — 
Notes on the Flora of Southwestern Connecticut. 
By L. N. JoHNsoN. 
_ Every season during the past ten years it has been the good 
fortune of the writer to spend. some weeks collecting in south- 
western Connecticut. As some of the finds were of interest these | 
notes have been prepared for the purpose of placing them on 
record. 
The face of the country is diversified, consisting of nearly 
parallel ridges running north and south, with their slopes about 
equally covered with woods of oak, chestnut, hickory and maple, 
and with cultivated ground. Every valley carries a stream, and 
following these a few miles to the south we come to the plain, 
which, varying in width, borders Long Island Sound, and fur- 
nishes the peculiar vegetation of the salt meadows and marshes. — 
Most of the collecting here described was done in the valley of 
Mill River, and in the shore region around Bridgeport. 
The ridge which runs north from Bridgeport finds its highest 
point in Tashua Hill, about six miles back from the shore. In the 
woods on its western slope, and in the adjacent valley, js an ad- 
mirable collecting ground. Here we find Cypripedium acaule 
growing abundantly, and with it Pogonta verticillata, Lipar's 
lilitfolia, and a number of other orchids, including rarely Cyp a6: 
pedium parvifiorum. UHere too grows Aristolochia Serpentaria-
