 acutely 3-angled but not winged ; in the upper part of the stem 2 or 3 leaves 

 often close together, the others distant, the floral ones or leafy bracts gradually 

 smaller. Panicles axillary and teriiinal, loosely pyrimidal, 2 to 3in. long, 

 forming a narrow leafy interrupted panicle of 1ft. or more. Inner bracts small.

 females usually nearer the base, the males many-flowered. Stamens 2 or 3. 

 Nut nearly globular, white, smooth and shining or slightly reticulate. Disk 

 adnate, with 3 broad obtuse lobes, the outer one not prominent. — R. Br. Prod.

9. S. Grseffeana (after — . Grsoff), Bcecl-d in Flora, 1875, 121 (from the 

 char, given) ; Benth. Fl. Austr. vii. 481. Stature and habit of S. margaritifera, 

 the leaves similarly collected 2 or 8 together in the upper part of the stem and 

 thfi sheaths not winged, but the leaves longer and narrower and , as well a^ the 

 angles of the stem quite smooth or scarcely scabrous. Panicles ovate-pyrimidal, 

 dense or rather loose, the terminal one 2 or 8in. long, and 2 or 8 distant axillary 

 ones smaller. Outer bracts leaflike ; inner ones not exceeding the spikelets or 

 here and there a subulate one rather longer. Spikelets numerous, unisexual, the 

 males about 2 lines long. Stamens usually 2. Nut globular, white, tubercular- 

 rugose or nearly smooth, glabrous or Sparingly pubescent, Outer persistent disk 

 at Irngth almost oupalar, inner adnate disk with 3 broad lobes denticulate at the 

 end.
