given to Baron Mueller, who had never visited tlie island, but 

 by whom the species were transmitted to Mr. Bentham. 



4. Mr. F. G. Waterhouse was sent in 1861 by the South 

 Australian Grovernment to search for insects and other zoological 

 objects, and as a result of byework about a hundred species of 

 plants were collected, which passed into the hands of Baron F. 

 von Mueller, by whom the novelties were specially dealt with 

 in vol. iv. of his " Fragmenta Phytographiae." Five species 

 new to science were the chief results of Mr. "Waterhouse's 

 labours, and eighty-three species-names added to the list of the 

 local flora. Mr. AVaterhouse had his head- quarters on the 

 Cygnet Eiver, at a few miles from Kingscote, and spent there 

 the spring and summer months. His collection of plants was 

 gathered chiefly from the wooded banks of the river and the 

 heath- ground adjacent thereto.

5. This small number of species recorded for so large an 

 insular mass as Kangaroo Island remained stationary until 

 1881, when largely influenced by the representations of Baron 

 Mueller, I visited the island towards the close of December in 

 that year, having for a companion Mr. S. Dixon. [I had 

 already in 1879 visited Hog Bay, but at an unfavourable time 

 of the year for botanical work.] My explorations extended 

 from Kingscote to the Cygnet Eiver, along the south shore of 

 Western Cove, to Mr. Buick's house on the American Eiver ; 

 thence a journey was made across sandy heath-country to 

 D'Estrees Bay ; from the American Eiver travelled along west 

 shore of Pelican Lagoon and Prospect Hill, and by the coast to 

 beyond the mouth of Hog Bay Eiver, inland to near the source 

 of that river, the return journey following the outward track. 

 The number of unrecorded species collected was 111 ; of these 

 the following six were at that time unknown to inhabit any 

 part of South Australia : — Cakile maritima, Wilsonia BackJiousii, 

 Styphelia striata, Ottelia ovalifolia, Caustis pentandra and 

 Dichelachne sciurea. 



6. Having failed to secure local help, especially in reference 

 to the collecting of vernal plants, I urged my young friend 

 and late pupil, Mr. E. S. Eogers, B.A., to undertake the task ;
