* * * * * The Ohio State Academy of Science held its eleventh annual meeting at the Ohio State University in this city on November 29th and 30th. Between thirty and forty papers were given and the attendance was considerably above the average. On the evening of the 29th a joint meeting was held with the Modern Language Association of Ohio, which held its annual session at the University on the dates mentioned above. The committee arranged an interesting and appropriate program for the evening and a large and appreciative audience responded. The Academy meetings have been held heretofore during the Christmas vacation, therefore holding it at this time was an experiment, but judging from the program, attendance, and enthusiasm manifested, the meeting this year may be said to be one of the best the society has ever held. * * * * * It is of more than ordinary interest to be able to record the taking of specimens of the European ruff, Pavoncella pugnax (Linn.) in Ohio. Two male specimens are in the Dr. Jasper collection at the Ohio State University, one taken April 28th, 1879, at Columbus, the other November 10th, 1872, at the Licking Reservoir. FIFTY ADDITIONS TO THE CATALOGUE OF OHIO PLANTS. W. A. KELLERMAN. The plants listed below have been found growing in the State without cultivation. A large number of them are adventive species but not hitherto recorded in the Ohio list. Three of the names occurred in the old lists and were noted in the Catalogue of 1893 by Kellerman and Werner, but were discarded in the Fourth State Catalogue, published in 1899. These here referred to and which are below restored to the Ohio list, are Nos. 683_a_, 1423_b_, and 1990½_a_. No. 893_a_ was included in L. D. Stair’s list of Railway Weeds. All the others are wholly new to the listed flora. While several persons have contributed to this increase, special thanks are due to Mr. Otto Hacker, who formerly as well as at present, contributed largely to a fuller knowledge of the State flora. Mr. Hacker has furnished specimens of all the species credited to him below and these are deposited in the State Herbarium. The rich field for adventive species in the region of Painesville may be understood when it is stated that the extensive and long-established nursery grounds of Storrs and Harrison are located at this place. 1_a_.
