136 HORN EXPEDITION — BOTANY. 



1875). It contains the names of 254 species, of which 114 belong to the Larapin- 

 tine flora, but as seventeen had already been recorded from Stuart's material, the 

 actual gain in numbers is reduced to ninety-seven, making a total known at this 

 time to be 129. 



Cotemporaneously with Giles, W. C. GossE crossed the western confines of the 

 Larapintine region in his traverse from Central Mount Wedge and Mount Liebig 

 to Mount Olga, and though he collected plants during his explorations, yet the 

 only record as regards this particular region is that of " grass trees " (s/c) in the 

 neighbourhood of Glen Edith. 



The Rev. H. Kempe, of the Mission Station at Hermannsburg, made succes- 

 sive collections of plants in his neighbourhood, which were determined by Baron 

 von Mueller, and their names were communicated in two lists to the Royal Society 

 of South Australia, and published in its Transactions, vol. iii., p. 129, 1880, and 

 vol. v., p. 19, 1882. The result of Mr. Kempe's investigations, as far as numbers 

 are concerned, is, at the latter date, 287 species, and of these 219 are records of 

 additional species, making the total known for the region 348. 



In 1889 Mr. Tietkens traversed the northern part of the Larapintine region, 

 from Alice Springs to its western limit, and added fifty-eight species, including 

 five new to science, to the Larapintine flora. A list of the plants collected by 

 him is published in the Trans. Roy. Soc. S. Aust., vol. xiii., pp. 94-109, 170-171, 

 1890. 



Lastly, from collections received by Baron von Mueller, during the period 

 intermediate between the two last-named, from the missionaries at Hermannsburg, 

 the officers attached to the Telegraph Stations at Charlotte Waters and Alice 

 Springs, and from other residents within the region, he has from time to time 

 published diagnoses of new species and records of others previously unknown in 

 this region. 



From the.se various sources of information I have compiled the accompanying 

 List of Plants, adding my records of localities of those plants actually ob-served in 

 life. Since the return of the Expedition Mr. F. J. Gillen, of Alice Springs, has 

 forwarded a collection of flowering plants gathered in his inuncdiate neighbour- 

 hood ; from it I am able to insert " Alice Springs " as an additional locality for 

 sever.al species. 



The number of species known previous to the advent of the Horn Expedition 

 wjis 502, which is now increased to 614. The additions are comprised of : new
