552 K. Domin. 
Bentham (Fl. Austral. VII, 563) placed this plant as a doubtful 
variety of Ar. ramosa R. Br. (var.? leptathera Benth.), but it has not only 
a quite different panicle and much smaller spikelets and shorter awns, 
but also nearly equal outer glumes. 
This new species appears to me to be closely allied with Ar. Behriana 
F. von Muell., which, of course, is easily distinguished by dense panicle 
nearly as broad as it is long. Ar. Behriana was recorded for Queens- 
land by Mueller, but neither F. M. Bailey nor I saw a single Queens- 
land specimen of this remarkable plant. 
5. Eragrostis trachycarpa Domin, nov. spec. 
(Er. nigra var. trachycarpa Benth. Fl. Austral, VII, 643.) 
Differt ab Er. nigra, cui est affinis, panicula permagna decomposita 
saepe plus 3 dm longa, sed praecipue spiculis longius pedicellatis, pedi- 
celis saepe plus quam 20 mm longis, caryopside globulari rugoso-tuber- 
eulata. 
Hab.: New South Wales and South Queensland. 
Having examined a great material of true Er. nigra from East India, 
I do not hesitate to place the Australian plant as a distinct species. 
Bentham says (l. c., p. 643) that the specimens from Australia differ 
slightly in their longer pedicels and more prominently rugose grain, but 
there is in addition a constant difference in the shape of the grains, 
those of Er. trachycarpa being globular, while Er. nigra has oblong 
grains, which on both ends are shortly truncate.
