margins and the lowest female spikelet on a long peduncle, 

 sometimes twice as long as the spikelet. C. inversa, R. Br. 

 Bordertown railway reserve (Dist. T). 



Cladium junceum, R. Br. Keith (Diet. T). 



Lepidosperma exaltatum, R. Br. Between Mount Gam- 

 bier and Glencoe; Dismal Swamp. Stems 1-1'50 m. high; 

 growing near water. L. longitudinal e, Labill. Myponga 

 (Dist. A; A. D. Black). L. concavum, R. Br. Stansbury 

 (Dist. Y) ; Tintinara; Keith (Dist. T). 



L. elatius, Labill., is given by Tate (Fl., 265) for the 

 Adelaide district, but the only specimen in his herbarium is 

 from Mount Macedon, Victoria. Mueller, in hi® Key to the 

 System of Victorian Plants, does not record it for any place 

 further west than his "Southern District," which includes the 

 country round Port Phillip as far west as Cape Otway. The 

 occurrence of this plant in our State seems doubtful. 



Chorizandra enodis, Nees. West of Bordertown (Dist. T). 



Restionaceae. 



Hypolaena exsulca, R. Br. Keith. First record of this 

 Western Australian species in our State. The male plant 

 appears indistinguishable from that of H. fastigiata, but the 

 female has flexuose branches covered with a white, almost scaly 

 tomentum ; style-branches very short, much thickened towards 

 the base. H. fastigiata, R. Br. Keith (Dist. T). 



Lepidobolus drapetocoleus, F. v. M. Keith; Bordertown 

 (Dist. T). 



Centrolepidaceae . 



Brizula pumilio, (F. v. M.) Hieron. Between Glencoe and 

 Lake Edward. Stems 1-3 cm. high. 



Centrolepis glabra, (F. v. M.) Hieron. Dismal Swamp 

 (Dist. G). Stems red, 20-35 mm. long; leaves shorter. 



Trithuria submersa, Hook. f. Dismal Swamp (Dist. G). 

 A dwarf, reddish plant, growing in mud ; involucral bracts 4, 

 not "5 or 6 or sometimes 1 or 2 more," as stated by Bentham. 

 Hooker (Fl. Tasm., ii., 79) says 4 ; Hieronymus (Nat. Pflanzen- 

 fam.) says 2-4. In the flowers I examined the 3 styles were 

 divided to the base into 2 branches. The name Juncella, 

 F. v. M., has been substituted for Trithuria by Hieronymus 

 in the Nat. Pflanzenfam., and by Maiden and Betche in the 

 Census of N.S.W. Plants, on the ground of priority, but as 

 Mueller's name was announced in 1854 without any descrip- 

 tion, it cannot, under art. 38 of the Vienna rules, replace 

 Hooker's name, published with a description in 1860. Mueller 

 himself accepted this position in his 1st and 2nd Census.
