— The Plant World for March, contains an article on "The 

 Adder' s-Tongue Ferns," by Mrs. E. G. Britton, in which the genus 

 is treated at some length. Illustrations of the outline and vena- 

 tion of the fronds of our North American species are given. 



— We have received from the author, Prof. T. J. Fitzpatrick, 

 Lamoni, Iowa, a copy of " Ferns of Iowa and their Allies." Forty- 

 one species embraced in nineteen genera are mentioned. Enough 

 keys and descriptive matter is included to enable the student to 

 identify any of the ferns he may find within the state. 



— The annual meeting of the Vermont Botanical Club was held 

 at Burlington, Vt., Feb. 4th and 5th, 1898. Upwards of a dozen 

 papers were presented ; among them was one by Rev. J. M. Bates 

 entitled "Among the Ferns." This consisted of an exhibition of 

 some eighty species of ferns from various parts of the world, with 

 remarks upon them. A note from Mrs. A. J. Grout recorded a 

 " New Fern From Vermont" which was believed to be a remark- 

 able variation of one of the Osmundas. 



— The two numbers of the " Student's Hand-book of Mushrooms 

 of America " that remained to be published have recently ap- 

 peared and are of the same excellent character as the others. 

 Number four deals with the well-known puff-balls and their allies, 

 and the following number treats of the poisonous Amanitas, with 

 observations on the poisons found in other groups. It is probable 

 that another series like the present will ultimately be issued to in- 

 clude the species not mentioned in this. 



— A most interesting and valuable contribution to fern literature 

 has just appeared from the pen of Dr. H. Christ, entitled "Die 

 Farnkrauter der Erde "*. It is a well printed volume of four 

 hundred pages and treats of some eleven hundred representative 

 species of ferns from all parts of the world. The species men- 

 tioned are described at considerable length, and two hundred ar d 

 ninety- one good illustrations add to the value of the text. The 

 author takes the middle ground in the matter of genera and recog- 

 nizes ninety-eight. We note the separation of the genus Struthi- 

 opteris from Onoclea, and the retention of Aspidium for Dryopte- 

 ris. Those who read German will find this book one worthy of a 

 place in their library.
