species is known from other parts of South Australia and from 

 New South Wales. 



3. Thryptomene ericcea, F. v. M., is, according to the author 

 of the "Systematic Census of the Plants of Australia," an 

 inhabitant of Victoria. 



4. Darivinia onicropetala, F. v. M., in a varietal form inhabits 

 Central Australia and also in the vicinity of Gruichen Bay. 



5. JSucalyptus Baxteri, which was established on Kangaroo 

 Island samples obtained by Eobert Brown, is antedated by 

 E. santalifolia, F, v. M. Eucalyptus diversifolia, Bonpland, 

 was founded on specimens obtained during Baudin's expedition, 

 The name has been abandoned in favour of santalifolia. The 

 species is known from the neighbouring parts of the mainland 

 and from West Australia. 



6. Acacia dodonceifolia^ Wildenow. One other station for it 

 is Port Lincoln. 



7. Convolvulus acaulis, Choisy, which was described from 

 Leschenault's specimens gathered on Kangaroo Island, repre- 

 sents merely an individual variation of the widely-spread Con- 

 volvulus eruhescens. 



Several apparently well-marked varieties have been described 

 and considered restricted to the island. With one exception 

 these varieties arise from the effects of wind and moist sea air, 

 as I have proved by tracking them from their maritime stations 

 inland until the normal form is acquired. The marked excep- 

 tion is var. acuaria of Grevillea parviflora, a species of the 

 Victorian Alps. I think that the Kangaroo Island plant has 

 fair claim to specific rank under the cognomen G. lialma- 

 turina. It has recently been gathered in the Port Lincoln 

 district by Mr. S. Dixon !
