Most of the notes in this paper are the result of a visit to 

 the 90-mile Desert and the South-eastern District made in the 

 end of November and the beginning of December of last year. 

 Several other collectors have also kindly furnished me with 

 specimens from various parts of the State, some of which are 

 dealt with here. 



Two species believed to be new to science, in the genera 

 Dicrastylis and Limnanthem,um, are described. 



The following species, native in other parts of Australia, 

 are here recorded for the first time in South Australia : — 

 Cardamine tenui folia, Ilydrocotyle plebeia, Hypolaena exsulca, 

 Goodenia humilis, Melaleuca fasciculi-flora, M . pauperiflora,

Aliens are indicated by an asterisk, and the new introduc- 

 tions recorded are : — A triplex patulum, Carthamus glaucus, 

 Dipsacus fullonum, Festuca elatior, Leontodon hispidus, 

 Medicago orbicularis, Moenchia erecta, Pentaschistis Tkun- 

 bergii.

 name of the district is given within brackets immediately after 

 the locality.
