The author regards these organs as of far greater importance than 

 the seeds in continuing the plant. The excellent plates illustrate 

 their anatomyand morphology.

This exhaustive and truly magnificent monograph of a difficult 

 order of plants comprises 556 octavo pages. The author has 

 personally visited all the larger herbaria of Europe and it was our 

 pleasure to meet him while the Kew specimens were undergoing 

 his investigation. A great number of new species are described 

 and the arrangement of genera adopted differs somewhat from 

 those of recent authors. Systernodaphne and Urbanodendron are 

 proposed as new, and Ariba, Aubl. is taken up as older than Ay- 

 dendron^ Nees. No change is made in the status of North Ame- 

 rican species, but Persea Carolinensis (which should be written 

 P. Borbonia, for this is the Latirus Borbonia of Linnaeus) is en- 

 riched with forma glahrhisctda (Pursli), Mez. and forma pubescetis 

 (Pursh), Mez. Dr. Mez very kindly worked up Dr. Rusby's 

 Bolivian Lauraceae and they are included in his work, Ocotea

An ac- 



count of the morphology and histology of the order is appended. 

 The plates show floral diagrams and morphological details.
