 members and one visitor in attendance. 



The donation to the Club's library was announced of two num- 

 bers of the Characeae Americanaehy the author, Dr. T. F, Allen. 



Plants exhibited,. — Prof. Wood exhibited and remarked upon a 

 number of specimens of |lants from the North-western Territories, 

 many of which are undescribed in American botanical works, and 

 will probably prove to be new species. Among other interesting 

 things was a specimen of Aster praealtus^ a species which has long 

 been lost sight of. Mr. Tweedy brought specimens of Adiantum 

 Capilliis-Veneris, L., gathered in Texas, and of Aspidium aculeatum, 

 Svvartz., var. Braunii, Koch, from Crane's Mountain, Warren County, 

 N. Y. Miss Knight called attention to the fact that the last-mentioned 

 fern was found by Prof. Benedict many years ago on Mount Marcy, 

 and again in 1874 by Miss Edith Gleason, on the trail to Preston 

 Ponds, in the Adirondack region, Essex County. 



New Stations. — Mr. Bicknell gave the upper end of New York 

 Island as a station for Aster amethystinus^ Nutt., Pycnanthemum 

 Torreyi^ Benth. and Desjuodium viridiflorum^ Beck. 



Albi?its7ni — -Mr. Britton reported that a white-flowered variety of 

 Cypripedium acaule^ Ait. had been detected the present season near 

 Bridgeton, N. J., by Dr. J. Potter. 



Large Cornus,^Mr. Britton also stated that at the last-named 

 locality he had observed a specimen of Cornus florida, L., the trunk 

 of which measured five feet and four inches in circumference. 



Teratology. — Mr. Bicknell exhibited several chestnut *'burs," each 

 of which v/as composed of two involucres which had cohered by the 

 edges of their contiguous valves so as to form but a single individual 

 having six valves and enclosing seven nuts, one of which was seated 

 directly on the line of cohesion. Mr. Bicknell also showed examples 

 of heterophylly in the apple-tree. The leaves exhibited were nearly 

 all deeply cut-lobed and sharply toothed, resembling those of Crataegus 

 coccinea, and were taken from a tree which had run wild in the upper 

 part of New York Island. 



A Weeping Apple-tree, Mr. Britton remarked on an accidental 

 variety of the common apple-tree which he had observed at Bridgeton, 

 N. J., the present season, some of the pendulous and trailing 

 branches of which were ten feet in length. The tree grew on the 

 farm of Dr. J. B. Potter. 



The President remarked at some length on the plants observed by 

 hmi in the Western Territories this season, and signified his intention 

 of exhibiting specimens to the Club as soon as they should be properly 

 arranged. 



One corresponding and two active members were elected.
