NOTES AND EXHIBITS. 495 



Hawkesbury River(Dr. J. B. Cleland); and Rose Bay(W. F. 

 Blakely). In Bentham's Fl. Aust.(vii., p.461), this species is 

 described under the name Paspalum hrevifolium Fliigge; and 

 Panicum tenuifforu7n R.Br., Prodr.p.l93, is quoted as a synonym. 

 It is interesting to note tliat Bentham included this species under 

 Panicum(iiect. Diyitaria) in Journ. Linn. Soc.(Bot.), Vol. xix., 

 p. 4 1(1 881), about three years after the last volume of the Flora 

 Australiensis was published. The species evidently has a wide 

 range, as it is included by Stapf in the Flora Capensis(vii.,p.380), 

 under the name Diyitaria tenuiflora Beauv. Specimens of the 

 common Summer Grass, Digitaria sanguinalis ScoTp., (Panicum 

 sanguinale Linn.) were also shown for comparison with the closely 

 allied D. debilis. 



Mr. A. A. Hamilton showed a grass, from the Hawkesbury 

 River district, which seemed to be an undescribed species; a 

 description has been prepared, which, together with some field 

 and other notes, will form the subject of a further communica- 

 tion. Also, from the National Herbarium, Sydney, a specimen 

 of Eriyeron bonariensis Linn., not previously recorded from Aus- 

 tralia. In a note on Erigei'on liiiifolius Willd., a common weed 

 known vernacularly as "Cobblers' Pegs," Bentham, in the Fl. 

 Austr.(iii., p. 496) says that " some of the above enumerated 

 specimens may belong to E. alhidus A. Gray," which is synony- 

 mous with E. bonariensis Linn., according to the Index Kewensis. 

 This proves to be the case, as there are examples in the National 

 Herbarium from a number of localities in New South Wales. A 

 brief description is given in Grisebach's Fl. Brit. West Indies. 

 E. bonariensis differs from E. linifolius in having smaller flower- 

 heads, the ligula of the ray florets more developed, involucral 

 bracts glabrous or nearly so, ray florets dark blue, and in its habit 

 generally. Specimens of E. canadensis Linn., E. linifoliusV^ iWd., 

 together with a specimen of E. bonariensis Linn., from the 

 Argentine, collected by Dr. Otto Buchtien, were exhibited for 

 comparison. 



Mr. Fred Turner exhibited two important indigenous grasses, 

 and nine interesting Cyperaceous plants from the Northern Ter-
