many. This however may have been overlooked because of the diffi- 
culty of observation in such a large mass of cells. 
_ The fungus was found in prothallia of Aspidium falcatum, Pteris 
- argyria, and P. cretica 
It was first Boncaibed by Lohde.’ Subsequently Leitgeb*? made it 
the subject of a thorough investigation, and grew it in a large number 
of species of fern prothallia—Gero. F. Arkinson, /thaca, lV. Y. 
Lemna Valdiviana in Massachusetts.—Several interesting botanical 
excursions have been made this year in the lands recently set apart by 
the state of Massachusetts for public parks 
By notice sent out by the superintendent of planting for the parks, 
the local botanists have had the opportunity of enjoying a seriés of 
pleasant field days and comparing the work done in different portions 
of the reservations. 
One such trip was taken on Sept. 3d through the Blue Hills region, 
eight miles south of Boston. This public park is thirteen miles in 
circumference and includes the highest land in eastern Massachusetts 
(Blue Hill, 636), as it is also the highest land on the Atlantic coast 
from southern Maine to Florida. It has long been locally famous for 
ifs rocky ledges, basin-like swamps, and, on its southern side, the ex- 
tensive meadows and ponds of two sorts, rocky, with clear waters, and 
marshy, with dark waters. 
The most interesting find on that occasion was a Lemna, which, so 
far as comparison with specimens at the Gray Herbarium shows, is 
Lemna Valdiviana Philippi; and I send this note of its occurrence So 
far north of its usual habitat, and would be very glad to have some 
southern or western Z. Valdiviana in exchange.—GEo. G. KENNEDY, 
Readville, Mass. 
Paceinia malyacearum.—Some years ago, the late Geo. W. Clinton 
of Buffalo, N. Y., expressed himself as disappointed because a certain 
Ranunculus did not turn out to be R. bulbosus. “Why can’t Buffalo 
have this plant?” 
We have rather desired at this place the presence of living Puccinia 
malvacearum, because it was so useful for the class room. This year, 
_ for the first time, it has been introduced with some hollyhocks oy 
chased at the east. It has already made serious attacks on hal 
dozen species of plants in our botanic garden and now that we ae 
os the thing doesn’t seem so funny.—W. J. Bea, 4 gricultural College, 
ich.
