glaiicum, which were exhibited. On a more recent excursion to 

 Staten Island the minute mosses Nanomitrium Austini and Ephc- 

 mcriiin spinulosmn were among the plants collected. 



]Mr. ^^^ W. Eggleston told of a field meeting with the Vermont 

 Botanical Club at W^illoughby Lake in July and of finding Woodsia 

 glabella, Woodsia alpina, Asplcnium viride, Dryopteris Goldicana, 

 Polystichum Braimii and Botrychium simplex. In the spring he 

 made a visit to the mountains of southwestern Virginia to investi- 

 gate for the Bureau of Plant Industry three plants that were sus- 

 pected of being poisonous to cattle. These were Delphinium tri- 

 corne, Bicuculla Cucullaria, and B. canadensis. The first two 

 were found to be very poisonous, the last slightly so. In the case 

 of Bicuculla Cucullaria most of the poison seems to be in the bulbs, 

 which are commonly lifted with the foliage by cattle, but are left 

 in the ground by nibbling sheep. 



Messrs. Raymond H. Torrey and C. C. A\'hedon reported that 

 Bicuculla Cucullaria is still to be found in the northern part of 

 Manhattan Island. 



Professor R. A. Harper had noted a peculiar Aecidiuni on 

 Bicuculla in Van Cortland Park. 



Professor Tracy E. Hazen spoke briefly of an undescribed genus 

 of filamentous fresh-water green algae related to Uronema. It 

 was found first in greenhouses in New York and later in a ditch 

 at Englewood, N. J- The past summer he had collected it also in 

 pools at Burlington, Vt., and Woods Hole, Mass. One peculiarity 

 of a second species of the genus is a periodic rotation of its lobed 

 chloroplast, this movement occurring night and day, and being 

 apparently independent of light conditions. 



Professor R. A. Harper reported the occurrence of Pediastrum 

 triangulum in plankton of Devil's Lake, North Dakota, which is 

 being studied by Dr. George T. Moore. It had previously been 

 known only from Germany. 



Miss Anna Runge mentioned finding luxuriant masses of 

 Habenaria lacera and Calopogon pulchellus on ]»»Iarthas Vineyard. 



Miss Dorothy Oak referred to the occurrence of two species of 

 Droscra in the town of Orleans on Cape Cod.
