I propose to give first a list of the plants collected by myself. 
Then will follow statistics of. the Desert flora obtained from all 
available sources.  Xerophily and homoplasy will next be briefly 
referred to; and after this some remarks will be made on the 
distribution of Desert plants in relation to the soil. 
The first set of the plants, it may be added, is at the British 
Museum. The second and third sets have been sent to Columbia 
College, New York, and the Kew Herbarium respectively.
