2 cm. long. In Gunn 588 the length is 1:8 cm., in Stuart’s from 
New England and Cunningham’s from the Brisbane River it is 
1-7 cm. In others a length of 2-2-2-3 cm. is attained. The 
column of the awn, though constant in texture, colour and indu- 
mentum, varies in length from 3-2 cm. (Cunningham) to 5 cm. 
(Stephenson 261 and Liotsky). In the present state of our know- 
ledge it would seem that Sieber 66 should be placed with 8. 
pubescens while S. eremophila might include all the other plants: 
formerly referred by me to S. rudis, Spreng.

This species is allied to S. tenwiglumis and 
S. elatior. From the former it differs in having 
smaller spikelets (lower glume 9 mm. long, upper 
glume 7 mm. long, valve 6 mm. long) and larger 
panicles about 30 em. long, and from both in 
its several-noded culms and branching habit, 
the non-convolute leaves 6-8 em. long and 
3-4 mm. wide, and the glabrous ligule about 
5 mm. long.

The lobes of the valves in this species were 
described as being 1 mm.long. I have examined 
them again and find that they do not as a rule 
exceed 0-5 mm. in length, and are sometimes. 
shorter or often only one is developed. Tepper’s 
plant is identical in every respect except that 
the lobes are entirely absent and that the 
- overmature panicle is still partly enclosed in its

Further microscopic examination of the glumes of Mueller’s 
plant shows that the appearance of three teeth or aristulae at 
their tips is due to the breaking down of the extremely delicate 
tissue between the very strong nerves. The tips of the glumes 
are therefore really entire and the total length of the latter must
