leaves whitened instead of green beneath as they should be in this 
species. The most marked distinction as given in descriptions 
between S. Zucida, Muhl., and the western S. /asiandra, Benth., is 
this very difference in the under surface of the leaf. It would seem 
from these specimens that either the distinction between the two 
species does not hold good or that S.. /asiandra, Benth., may be 
found in this region. This is a problem needing further observation 
and study. 
While we were crossing a sandy field near the swamp many plants 
of yellow-flowered Oxalis were noted and a careful investigation 
showed there were three very distinct forms. Plentiful material was 
taken and afterward determined by Mr. Fernald. The species proved 
to be O. cymosa, Small, O. stricta, L., and O. filipes, Small. In the 
field there were such differences of appearance and habit that after 
a little the three species could: be distinguished at a glance. Our 
common species, O. cymosa, Small, was in its early stage and was 
less branched and more pubescent than it appears later in the sea- 
son. It had simple erect stems covered with a spreading pubes- 
cence, a thick root-stock, and small flowers. . O. stricta, L., had 
larger flowers, slender rootstock, ascending slender stems branching 
at the base, and appressed pubescence. O. filipes, Small, had 
spreading pubescence like that of O. cymosa, Small, but was entirely 
different in habit, having small spreading stems almost wiry at the 
base, and slender much branched running rootstocks, the plants 
spreading to form tufts or mats. This last species was collected the 
following day in the town of Sheffield, Massachusetts. 
In Tich ground along a fence-row a plentiful supply of Ranunculus 
allegheniensis, Britton, was secured, Crossing a moist meadow on 
our way to take the train for return, Judge Churchill discovered a 
few plants of Carex formosa, Dewey, and thus added another sedge 
to the Connecticut list. Later in the day this species was found at 
another station near Lakeville. In the afternoon a piece of rich 
woodland on a rocky hillside gave good specimens of Carex 
oligocarpa, Schk., Avena striata, Michx., and ea debilis Torr.; 
while an excursion to the foot of Sage’s Ravine yielded Streptopus 
amplexifolius, DC. 
The last day was mostly spent in an unavailing search for the 
long lost globeflower, Z»o/Zws laxus, Salisb. This was collected 
many years ago in Cornwall, Connecticut, but has never since been
