Obs. The genus Eremophila was founded on very un- 

 satisfactory materials, namely, on two species, E. oppositi- 

 folia and alternifolia, which I found growing in the same 

 sandy desert at the head of Spencer's Gulf in 1802, the 

 only combining character being the scariose calyx, which 

 I inferred must have been enlarged after flowering. This, 

 however, proves not to be the case in E. alternifolia, which' 

 Mrs. Grey has found in flower towards the head of St. 

 Vincent's Gulf; and from analogy with other species since 

 discovered, it probably takes place only in a slight degree 

 in E. oppositifolia, whose expanded flowers have not yet 

 been seen. 



In 1817 Mr. Cunningham, in Oxley's first expedition, 

 discovered a third and very remarkable species in flower 

 and unripe fruit, which he referred, with a doubt, to Ere- 

 mophila, and which M. Alphonse De Candolle has recently 

 separated, but as it seems to me on very insufficient grounds
