ScHRENK, Joseph. A. G. Nathorst on the Nomenclature of the Leaves 

 of Fossil Dicotyledons. (Bull. Torrey Botan. Club, vol. xiii, No. 3, 

 p. 38, March, 188C. New York.) 



Abstract and trauslatiou of an article by A. G. Xathorst, in vol.xxv, numbers 

 1 and 2, of the Jiotanisches Centralblatt, on tlie difficnlties which present 

 themselves to the paleontologist in classifying and naming fossil dicoty- 

 ledons on the characters of their leaves only, and proposes to designate 

 those species of which the leaves only are known by the name of the genus 

 with which they agree best, with the addition of the termination j>/(i'N«m. 



In order to meet anotber difficulty, the author proposes to adopt a ternary 

 nomenclature. Suppose a leaf were found in Japan which resembles Acer 

 trilohatum so much that it would not be advisable to make A new species of 

 it, although the similarity is not perfect ; this leaf ought to be called Acer 

 frUohatum JajjoiiicioiK
