work. As all these books and papers are alluded to in the text, and in many 
cases rather fully summarised, the detailed nature of the work will be realised. 
This latter feature will make it invaluable in a country with limited library 
facilities, and such a consideration should serve to counterbalance the some- 
what high cost of the work. 
The book is bound in the style of West’s Algae in the same series, though the 
illustrations do not, in many cases, do justice to the plants they picture. 
Lichens are always difficult subjects for the photographer, and no doubt many 
of the photographs used to illustrate the text have suffered in reproduction. 
It is to be hoped that the work will afford a much needed stimulus to 
lichenology in South Africa, and all botanists will owe a debt of gratitude to 
Miss Lorrain Smith for the exceedingly able manner in which she has presented 
and made readily accessible a vast fund of information.
