 Territory, viii+287 p., 24 pi. McCarron, Bird and Co.: Melbourne, 1917.] Jour. Botany 57: 

 69-71. 1919. — The title is said to be in some respects a misnomer because of the range included. 

 Access to types would have avoided many mistakes into which the authors have fallen. New 

 species and genera are included; some names in opposition to the Vienna Laws. In its gen- 

 eral get-up the book is very unsatisfactory. Poor arrangement and typography are criti- 

 cised. "There is no need to pursue a criticism which might be indefinitely extended, and 

 which is undertaken in the hope that it may influence future publications from the same 

 source." — K. M. Wiegand.
