DESCRIPTION OF PLATES. 



Plate XXXII. 



Fig. 1. General view on NuUarbor Plain showing typical 

 bluebush (Kochia sedA folia). A donga is seen on the left. The 

 trees in tlie donga are Acacia aneura, Pittosporum philhjraeoideSy 

 and Fusanus acuminatus. The soil of tlie plain shows white lime- 

 stone fr<agments, also the flower heads of Cephalipterum Dtuth- 

 mondii. 



Fig. 2. Transition region between plain and sandhill. The 

 trees are not confined entirely to depressions (dongas), though 

 one with a denser tree flora is seen to the left. The main tree is 

 Acacia aneura, with, occasional A. tetragonophylla and Eremophila 

 Latrohei. etc. Atriplex vesicarium is the chief ground shrub, the 

 soil here being more sandy than on the plain (cf. fig. 1). Numerous 

 annuals are present.
