EDWARD P. BIQELOW, rianaging Editor. 



Mr. A. LeRoy Andrews, having undertaken to revise the genera: 

 Aschisma, Astomum, Hymenostomum, Weisia, Gyroweisia, Gymnos- 

 tomum, Hymenostylium, Molendoa and Eucladium of North Ameri- 

 can mosses, would be glad to examine specimens of these genera, also 

 of Anoectangium, from any locality. American collectors are espe- 

 cially urged to be cn the look-out for Aschisma, Hymenostomum, Gy- 

 roweisia, Eucladium, Anoectangium and the plant now passing as Mo- 

 lendoa tenuinervis Limpr, as these are undoubtedly more widely dis- 

 tributed in North America than present collections would indicate.
