290 NOTES AND EXHIBITS. 



with toothed, and the latter with entire margins), the variation 

 noted is inconspicuous. 



Mr. E. Cheel exhibited, and offered observations on fresh speci- 

 mens of Red Clover {Trifolium pratense-perenne) infested with a 

 Rust [Uromyces trifolii (Alb. & Schw.) Wint.; or U. fallens of 

 some authors]. This plant was originally exhibited at a Meeting 

 of the Society [These Proceedings, 1913, pp.171, 397]; when it 

 was shown that a plant which was infested with Rust at Hill 

 Top, was able to resist the attack of the fungus when grown in 

 better soil at Sydney. The plant exhibited at the July Meeting 

 of 1913 was divided into two; one portion was planted in good 

 soil at Ashfield; and the other transferred again to Hill Top. 

 Both plants made fairly vigorous growth; and, so far, the Ash- 

 field plant showed no signs of Rust; whilst the plant transferred 

 to Hill Top had again developed Rust very badly. Mr. Cheel 

 also exhibited specimens of — Erechtites mixta DC, which he had 

 collected at Nethercote Road, Eden, Twofold Bay, in December, 

 1903; and at Hill Top, Southern Line, in April, 1914. This 

 species has previously been recorded only from Piper's Hill (in 

 the interior?) by Bentham (Fl. Aust., iii., 659;; and from the 

 Blue Mountains (Moore & Betche's Handbk. Fl. N.S.W., p.298). 

 — Dysphania littoralis R.Br., (Syn. ID. myriocephalus Benth.); 

 Penshurst (E. Cheel; October, 1911). Attention has recently 

 been drawn to this plant as containing hydrocyanic acid, and, 

 therefore, to be regarded as a virulent stock-poison (Queensland 

 AgriculturalJournal, June, 1915,p.264).- Erythrcea Centaurium 

 Linn. Specimens of this species, collected at Chatham, Kent 

 (England), in July, 1905, together with specimens of plants col- 

 lected at Penshurst, near Sydney, in November, 1898, were ex- 

 hibited. These appeared to the exhibitor to be identical. This 

 species seems to be widely spread, chiefly in the coastal districts 

 of this State, extendiug to the Blue Mountains on the Western 

 Line, and to Goulburn on the Southern Line. It has evidently 

 been mistaken for E. australis R.Br., which seems scarcely dis- 

 tinct from E. spicata Pers. The latter is being further investi- 

 gated.
