S93 On tJie Genus Hrewophila. 



More desiroup, however^ to avail myself of this oppor- 

 tunity of bringing some of the rarest and most elegant 

 desert plants of Australia under notice, than to enter into 

 an elaborate essay on the species, for which, moreover, the 

 Western Australian forms are but partially at my command, 

 I beg to limit these notes to a diagnostic definition of 

 Uremophila Freelingii^ discovered by Mr. Hawker in Capt. 

 Freeling's Journey to Lake Torrens, and to EremopJiila 

 Behrii, a plant of the South Australian desert, on which 

 more than nine j^ears ago I bestowed the name of its 

 discoverer. Dr. Hermann Behr, a physician and naturalist 

 of great learning and acute observation, now carrying on 

 his researches in California. 



To the definition of these a simple enumeration is added 

 of all the species hitherto described, merely to serve as a 

 temporary systematical disposition, until all the connecting 

 forms, which probably will be found to predominate in 

 Central Australia, and which the new expeditions into the 

 interior are likely to reveal, shall be discovered. 



In collecting all the species of 'Eremophila, Pholidia, and 

 StenocMlus under one universal generic appellation, prefer- 

 ence has been given to the expressive name Ih'emophila ; 

 not only because it is so well adapted for all these plants, 

 (all without exception being restricted to the desert tracts 

 of Australia), but also as it claims eqaral right with those 

 of Stenochilus and Pholidia in regard to priority, whilst 

 neither of the latter names applies to the generality of the 

 species. 



If in these plants the principal form which the corolla 

 assumes is to be regarded as a distinct mark of the 

 genera, then the former arrangement of the species has to 

 undergo a considerable change, according to the combi- 

 nations of a scarious enlarged calyx of Eremophila, or an 

 almest unaltered calyx of StenocMkis or Pholidia, with the
