Boorman’s plant differs from the type (Etheridge) in having 
larger spikelets with unequal glumes, the lower being 1-8 cm. long 
and the upper 1-4 cm. long. The valve is 7 mm. long with a 
tuft of hairs about 2 mm. long at the apex and the awn 4-8 cm. 
The hairs on the valve are longer than in typical S. denszflora, 
while those on the awn are slightly shorter.

The three species S. mollis, S. nobiles and ‘s. pibibabiia are 
very closely allied. The following differences will ‘supplement 
or amplify those already given in the Key. 
In S. mollis the hairs of the long flexuous awn are present all 
along the bristle except at the extreme tip, and are about 2 mm. 
long. The bristle is very long, usually about 6-7 cm. 
In S. nobilis the hairs are usually denser and longer (2-3 mm.) 
than in S. mollis or in S. semibarbata, and are not continued. 
beyond a few mm. of the base of the bristle, which varies in 
length between 4 and 6 cm. and turns black at maturity. In this, 
as in the preceding species, the column of the awn does not exceed 
2-5 cm. in length. 
In 8. semibarbata the column measures 3-5-4-5em. The hairs 
are generally scanty, 1-5-2 mm. long and not continued beyond 
the column. The bristle rarely exceeds 4:5 cm. but in a few 
cases has been found to be as long as 6cm.; it also usually turns 
black at maturity.

After careful comparison this plant was found to agree, not 
with the type of S. rudis (Sieber Agrost. 66), but with the other 
specimens quoted for that species in Kew Bull. (1921) 21. 
‘Since writing that enumeration a more complete specimen of 
. Stieber Agrost. 66 was lent by the British Museum for examination. 
The fully matured floret and awn show a marked difference from 
the other specimens formerly believed to be identical. The hairs 
of the valve are whitish and the stout column of the awn pale. 
Thus although the lower glume is only 1-4-1-5 cm. long there 
seems no character to keep it distinct from 8. pubescens, R. Br. 
The type of the latter species (Brown 6203) has the lower glume —
