nabina, develops unusually large individuals, eight feet high and 
an inch through at the base. A colony of the great horsetail, 
Equisetum hyemale, borders what appears to be a kettle hole 
depression. 
The boulder beaches are interesting, with a variety of ice 
worn fragments from far and near, diabase from the ridge of the 
Tors, opposite; norites from the Blue Mountain region, granites 
and gneisses from the Highlands of the Hudson and quartzite 
cobbles from just beyond, slates and limestones from the middle 
Hudson, Catskill sandstones and conglomerates, and Taconic 
hists.

The trip to Fresh Kills, Staten Island, partly on account of 
the fact that the route taken was slightly different from that of 
last year, yielded several species not found before. A new sta- 
tion was located for Robinia viscosa Vent., the clammy locust, 
namely at the foot of the hill opposite the church, near the start 
of the trip at Richmond. The route was rich in polygonums, P. 
hydropiperoides, arifolium, and sagittatum being found in the 
brook at the beginning of the trip, and nearby also the rarer P. 
Muhlenbergit, with P. pennsylvanicum of course common in 
many places throughout the day. Besides these, P. scandens the 
climbing false buckwheat was seen, and, toward the end of the 
day, what appeared to be P. orientale, the prince’s feather. 
Other noteworthy plants collected were Angelica villosa, Eupa- 
torium verbenaefolium, Panicum virgatum and Tridens flava, 
Acnida cannabina, the water hemp, and Aster tenuifolius and 
subulatus. The last two are salt marsh asters and are very simi- 
lar, but the former is perennial, while the latter is annual, with 
much smaller flowers than in tenuifolius. Only a few plants of 
Sabatia stellaris, the beautiful sea pink, were found in flower,but 
Pluchea cam phorata, the salt marsh fleabane, was present in fair 
abundance. Iva and Baccharis were plentiful and in flower as 
usual. Eighteen members and guests comprised the party.
