Tastnauian plants, and have shown a degree of variability of 

 many species much higher, than could have been anticipated 

 from local studies. Eliminated from the present index are 

 several plants formerly regarded as indigenous, and it is 

 almost certain, that some others ought yet to be transferred 

 from the list of indigenous to that of the introduced species. 

 A clear aspect of the original vegetation becomes disturbed by 

 mixing the naturalized with the natural plants ; the number 

 of the latter may at last become fixed, but that of the former 

 •will increase constantly. An enumeration of such foreign 

 plants as are settled beyond extirpation in the island, will 

 form part of the next chapter of this dissertation. A few 

 other plants, accepted in Dr. Hooker's works, have also been 

 excluded here, as their specific validity remained yet obscure. 

 They must find, if necessary, a place in supplemental notes to 

 this compilation. It is also intended to continue this 

 essay in other directions, while statistic labours on the 

 plants of the colony Victoria are progressing, inasmuch as 

 the vegetation of each of the Australian provinces can only 

 be fully elucidated by comparative studies. Material which 

 Tasmanian residents, imbued with scientific taste, will be 

 inclined to secure for the purposes indicated, will be grate- 

 fully utilized, and will tend to advance the knowledge of the 

 indigenous vegetation towards gradual completion. Finally 

 then also an inexpensive volume on the native plants of the 

 island and its dependencies might emanate from augmented 

 material and extended studies for educational purposes, recre- 

 ative intellectual occupations, utilitarian references or further 

 contributions to science.
