crossed by the Jersey Central railway further up. In this connection it may be 
of interest to note that the occurrence of Sphagnum species in New Jersey is 
likely to be fairly uniform along a given water-course, varying only insofar that 
some species require still water in the form of a natural or artificial pond; but it 
is entirely impossible to predict what will occur along a different water-course. 
In several days of the summer of 1913, with headquarters at Island Heights, I 
sectioned all of the water-courses from Toms River to Oyster Creek south of the 
three* branches of Forked River, many of them at two and one at three points, 
which, added to the work in the same locality in the summer of 1911, brought 
out the above-mentioned facts in a striking way. These facts seem to show the 
difficulty of the conveyance of Sphagnum spores (many of the New Jersey spe- 
cies fruit there rarely if at all) across the stretches of dry pine-barrens, and thereby 
only increase one’s wonder as to how such a remarkable number of species or- 
iginally “got there” and what determined their present inexplicable irregularity 
of distribution. In the pond on the North Branch of Forked River by the 
Forked River railroad station S. portaricense was well established, but entirely 
without the companions, S. Pylaesii and A. cyclophyllum , in its station at Toms 
River.

REVISED LIST OF HEPATICS COLLECTED IN AND NEAR WORCES- 
TER, MASSACHUSETTS 
Helen E. Greenwood 
A preliminary list of Hepatics collected within the limits of Worcester, 
Massachusetts, by Miss Helen E. Greenwood, was printed in the January Bry- 
ologist for 1910. Since that time the collector, having gone farther afield, has 
increased the number of specimens sufficiently to make it seem worth while to 
print a revised list. As before, all the Hepatics listed below have been col- 
lected by Miss Greenwood, either in Worcester or in the nearby towns. The 
accompanying notes indicate whether the plants occur in large or small numbers. 
Comparison with the former list will show that Cephalozia serriflora, which 
appeared before, has been withdrawn, not only because it has not been found a 
second time, but also because there has arisen some doubt as to the correct 
naming of the specimen in the first place. For a time it seemed certain that 
Cephalozia lacinulata and Cephalozia macrantha might find a permanent place 
on the list, one authority being sure that an authentic specimen of each had 
been found; but lack of agreement among those consulted makes it undesirable 
to include these in the main list at present. Of the 62 different species listed 
below there are only four that can lay any claim to rarity or distinction of any 
kind. Of these, Nardia Geoscyphus at the time it was sent into the Society 
Herbarium, had been collected only three times previously in the United States, 
thus making Worcester the fourth station. 
Jungermannia pumila , Mylia anomala , and Cephalozia fluitans were new 
additions to the Massachusetts list.
