large, very thin. Stamens 6, rarely 3. Styles short, distinct. Grain 
enclosed in the larger glumes but free from them.

* 1. E. longiflora, Sm. Ic. Ined. t. 32.—An erect glabrous grass, 
attaining 2 or 8 ft. but often much smaller. Leaves flat, sometimes 
rather long, slightly scabrous. Panicle loose, narrow, 3 to 6 in. long, the 
branches and pedicels filiform. Outer persistent glumes obtuse, 2 to 3 
lines long, often purplish, the 2nd rather longer than the first, 3rd and 
4th glumes 3 to 4 lines long, scabrous-pubescent, rigid, 3-nerved, 
tapering into an awn as long as themselves, and each with a tuft of 
hairs at their base on the slightly elongated rhachis, the 4th contracted 
into a short stipes, 5th and 6th glabrous, unawned. Stamens 6, or 
rarely in afew flowers reduced to 5 or 4.—Swartz in Trans. Linn. Soc.

into Australia on the other. 
W. Australia, Drummond, n. 142. The specimens seen rather numerous but 
unaccompanied by any memoranda. I can find nothing to distinguish them from the 
South African E, brevifolia, and therefore conclude them to represent an introduced 
Plant. Although the number of stamens is not known the inflorescence 1s that of 
Ehrharta not of Tetrarrhena.
