flowering glumes with very prominent nerves and the other charac- 
teristics given above. It seems to be limited to the single species 
which is rather rare in the Blue Mountains of New South Wales. 
The general aspect of Notochloe microdon is that of a large Festuca.

Bentham named this plant in schedis Eriachne pallescens R. Br., 
which is however quite distinct, having an entire and not biaristate 
palea. Our new species approaches in some respects the East Indian 
Er. triseta; of the Australian Eriachne species Er. aristidea F. Muell. and 
Er. pallida F. Muell. have a bifid palea, the points tapering into an awn, 
but both are readily distinguished from Er. Muelleri. 
Although I saw only a single and not quite perfect specimen of Er. 
Muelleri, | do not hesitate to describe it as a new species as the charac- 
teristics given above distinguish it from all other congeners. Hriachne 
triseta, which seems to be the nearest ally, may be easily recognised 
by its stouter habit and much bigger spikelets. 
In addition I will mention, that there is some confusion about the 
Eriachne ciliata of Robert Brown, some of the type-specimens being 
quite different from the true Er. ciliata, as described by Rob. Brown.. 
Bentham, Bailey and others. The plant from Arnhem Land (R. 
Brown, Iter Australiense 1802—1805 no. 6264) may be regarded as the 
type of the species corresponding to the original description. This is a 
slender and small annual and is found also near Port Darwin and Es- 
cape Cliff[ But under the same number (6264) there is in Herb. Brown 
quite a different plant gathered at Broadsound (Queensland), apparently 
a perennial with rigid leaves, bigger spikelets, mucronate outer glumes 
and with very shortly awned flowering glumes; this form was not- 
withstandig put under the true Er. ciliata by Bentham and J. F. 
Bailey.
