Dr. N. L. Britton spoke briefly of the new^ New York State 

 Museum Bulletin, No. 254, entitled "An annotated list of the 

 Ferns and Flowering Plants of New York State", by Dr. Homer 

 D. House. This work includes records of stations, and biblio- 

 graphical references to date, making use also of the large amount 

 of material available at the Museum herbarium at Albany. Dr. 

 Britton stated that Teesdalia nudicauUs found by Bicknell on 

 Long Island was not recorded. A specimen of this from the 

 herbarium of the New York Botanical Garden Avas exhibited 

 and Dr. Britton remarked that a record of the find may not 

 have been published. Dr. Britton felt that there were, perhaps, 

 some inconsistencies in the work; e. g. in the Orchidaceae, Dr. 

 House recognizes such genera as Gymnadeniopsis, Limnorchis, 

 Lysias, Blephariglottis, etc., but in the Lentibulariaceae he does 

 not divide Utricularia into the different genera of Barnhart. 



" Photoperiodism in Chara" was the title of the talk which 

 followed, by Mr. J. S. Karling. As to periodicity in the fructi- 

 fication of algae, there are two ideas prevalent: either that 

 environmental conditions do not greatly aiTect the development 

 of sexual organs, and that it is the result of inherent or inherited 

 tendencies, or that the periodicity is entirely determined by 

 external conditions. 



Chara fragilis, the species worked with, is said to fruit natur- 

 ally from June to September. Mr. Karling stated that by pro- 

 longing the day with the use of artificial illumination, the devel- 

 opment of antheridia and oogonia can be induced abundantly
