XXll. ABSTRACT OP PROCEEDINGS. 



The discussion on the subject of the Presidential Address was contributed to 

 by Dr. Anderson, M^essrs. Blakely, Dr. Ferguson, Fletcher, Goldfinch, A. G. 

 Hamilton, Hull, Le Souef and Dr. Walkom, the President replying to varioas 

 questions raised. 



NOTES AND EXHIBITS. 



Mr. T. Steel exhibited a young Ryla coendea having two bots of the frog 

 bot-fly (probably a species of Batrmhomyia) , one on each shoulder. 



Mr. W. F. Blakely exhibited from th« National Herbarium, Cenchrus pauci- 

 flerus Benth., one of the North American sandburrs or "Bun- grasses," which has 

 been received for the firet time from three widely different localities during the 

 last four months, namely, Narrabri ( Stock Inspector Brigg) , Manildra district 

 (A. H. T. Sherwin), Kelso (E. Ray). It is alleged to have been introduced into 

 the two latter districts in "Sudan Grass" seed. There is another specimen in the 

 Herbarium labelled Western Australia (Dr. F. Steward, 1916). Wherever the 

 Burr Grasses have become established they are spoken of as "vile weeds" — the 

 burr-like involucres are a serious menace to man and beast. This species is des- 

 cribed and figured by Agnes Chase, who has revised the North American species 

 of Cenchrus (Cont. United States Nat. Herb., xxii., pt. i. 1920, p. 67). It is 

 closely allied to C. tribuloides L., from which it is distinguished by its smaller, 

 finely pubescent burrs, in contradistinction to the larger and densely woolly burrs 

 of C. tribuloides. 



Mr. Fred Turner exhibited specimens of Euphorbia lathyris Linn., received 

 from Mr. E. Baird, Multagoona, Darling River. The exhibitor had never col- 

 lected this plant west of the Darling R., nor had he previously received it from 

 that part of the State. According to Dr. Robert Bentley the seeds are "purgative 

 and yield by expression a very active cathartic oil." The plant is recorded in 

 Turner's "Catalog-ue of Introduced Plants" (Agric. Gaz. N.S.W., i., p. 304). Mr. 

 Turner also stated that Saponaria ealabrica Guss. recorded as new for the State 

 (These Proc, 1921> p. 349) was listed in Australian seedsmen's catalog-ues and 

 cultivated in gardens as a border plant more than forty years ago.
