Floating leaves 15-nerved. First record for South Australia ; 

 the type came from the Murrumbidgee River, N.S.W. P. 

 Tepperi, A. Benn. Finniss R. (H. Griffith); drains at 

 Millicent. Upper leaves 19-23-nerved ; those of the Millicent 

 specimens are broad-ovate or quite orbicular. 



Gramineae. 



Lepturns incurvatus, Trin. Robe (C. D. Black) ; Beach- 

 port (Dist. G). 



Danthonia penicillaia, (Labill.) F. v. M., var. racemosa, 

 Maid, et Betche. Cheltenham; Keith; Millicent; Bordertown. 

 A small grass 20-30 cm. high, with filiform, hispid leaves ; the 

 short broad outer glumes and short awn not much exceeding 

 the lateral lobes give it the aspect of D. carphoides, F. v. M., 

 but the lateral lobes are twice as long as the base. 



Calamagrostis aemula, (R. Br.) Steud. Beachport. In 

 south-eastern specimens the bristle of the rhaehilla is \ or -| 

 as long as the flowering glume, and the spikelet is 6 mm. long, 

 while in the midland and northern specimens the bristle is 

 very short or the rhaehilla is merely produced in a tuft of hairs 

 at the base of the palea," and the spikelets are rather shorter. 

 An inland form with the ordinary small spikelets, but with the 

 panicle much exceeding the leaves, as in var. Billatdieri, is 

 found at Millicent and Kybybolite. Mr. E. S. Alcock states 

 that it is known at the former place as "Blown grass," because 

 the ripe panicles are broken off near the base of the brittle 

 stems and collect in bunches along the fences. Var. plebeia, 

 Maid, et Betche (Deyeuxia plebeia, Benth.). Beachport. 



Glyceria fluitans, R. Br. Dismal Swamp (Dist. G). 

 Rooting at the nodes below water ; erect stems 1-1*50 m. high. 



Poa caespitosa, Forst., var. laevis, Benth. Beachport. 

 Not tall ; leaves filiform, smooth ; panicle contracted, short 

 (about 3 cm. long). Var. tenera, Benth. Caroline scrub. 

 Rootstock creeping ; stems more or less procumbent ; panicle 

 1-2 cm. long, lowest branch solitary, or the panicle reduced to 

 a raceme of 2 or 3 spikelets, each containing only 2-3 flowers. 



Stijm fiavescens, Labill. Robe; Beachport (Dist. G). S. 

 setacea, R. Br. Bordertown (Dist. T). S. pubescens, R. Br. 

 West of Bordertown; Keith (Dist. T) ; Beachport (Dist. G). 

 S. teretifolia, Steud. Robe (C. D. Black) ; Beachport (Dist. G). 



Amphibromus nervosus, (R. Br.) Hook. f. (A. Neesii, 

 Steud.). Belair road. Brown's original specific name cannot, 

 under the laws of nomenclature, be rejected in favour of 

 Steudel's later appellation. 



Sporobolus indicus, R. Br. Naracoorte (Dist. T; H. W. 

 Andrew).
