The following list contains the names of plants recently 

 found growing spontaneously in South Australia, with notes 

 on two species already recorded for this State. The aliens 

 (distinguished by an asterisk) are additions to those described 

 in the "Naturalized Flora of South Australia," and the Aus- 

 tralian species are supplementary to those given in Tate's 

 "Flora of Extra-tropical South Australia," or subsequently 

 recorded in the Proceedings of the Royal Society : — 



Fumariace^e. — *Fumaria densiflora, DC. (considered by 

 some botanists as a variety of F. officinalis, L.). Adelaide 

 plains. — A native of Europe. 



PolygalacejE. — *Muraltia Heisteria, DC. Roadside be- 

 tween Morialta Gully and Norton's Summit. — South Africa. 



Caryophyllace^. — *Alsme tenuifolia, Crantz. Port 

 Lincoln (H. H. D. Griffith).— Europe. 



Linace^e. — *Linum gallicum, L. Roadsides, Balhannah. 

 — Mediterranean region. 



Leguminos^e. — Pultencea adunca, Turcz. Warrunda, 

 Port Lincoln railway (H. H. D. Griffith). — Western Aus- 

 tralia. Determination confirmed by Professor Ewart on com- 

 parison with specimens in the National Herbarium, Mel- 

 bourne. The leaves of all our specimens are scabrous and 

 hairy, without any hooked point. *Vicia sativa, var. angus- 

 tifolia, Ser. (V . angnsti folia, Roth). Roadsides near Crafers. 

 —Europe. 



Composite. — *Erigeron canadensis, L. Roadsides, Ren- 

 mark (E. C. Black). — North America. 



Note on Olearia picridt folia, Benth. (Plate i.). — This 

 handsome shrub, reported in FT. Aust., iii., 487, from the 

 neighbourhood of Lake Torrens, and not mentioned in Tate's 

 work, has been found in the remaining scrub at Halbury 

 and Strathalbyn. The heads of the Halbury plants are 

 larger than those from Strathalbyn arid contain more rays 

 — about 30 as against 15. Professor Ewart found that the 

 specimens agreed with the types from Lake Torrens. This 

 species differs from 0. rudis, F. v. M., in the narrow, entire 

 leaves, slender branches, and short outer row of pappus- 

 hairs.
