Bolus, H., Icones Orchidearum Austro-Africanarum 

 extratropicarum. II. (Wesley & Son. London 1911.) 



Vol. II was completed just before the author's death. It contains 

 100 plates, mostly partly colored, of South African orchids, almost 

 all of which were drawn from life. There are two new species 

 Mystacidium Aliciae and Eulophia Pillansii. It is a valuable contri- 

 bution to S. African botany, and we learn that a number of addi- 

 tional plates have been prepared which it is hoped to publish.
