W. AustraLia. Swan River, Drummond; near Fremantle, 
among limestone hills, Oldfield 1004; “in arenosis silvae prope 
Pine-Apple, Perth,” Preiss Herb. no. 1826; Leederville, Stoward 
935; Gordon River, Oldfield 675; Bridgetown to Kojonup and 
Slab Hut Gulley, Dorrien-Smith. 
S. Austratia. Mt. Lofty Range, Belair, Koch 937; French 
Island, Beveridge; King George’s Sound, Collie. 
TasMANIA. Penquite, Gunn 1480, Dec. 1845; Port Dalrymple, 
Brown 6204*. 
S. campylachne, as described by Nees in Pl. Preiss. ii. 99, 
seems to be a plant with smaller spikelets (13-14 mm.) and shorter 
valves (6 mm.). I have not seen Preiss’s specimen no. 1848 on 
which the species was primarily based, and am_ therefore 
doubtful as to its identity. Nees and Bentham (Fl. Austral. 
vil. 569) also quote a specimen of Drummond’s from the Swan 
River under S. campylachne and S. semibarbata var. campylachne, 
respectively. The specimens of this variety as written up by 
Bentham himself are certainly identical with S. semibarbata,

N.S. Waues. Port Jackson, Brown 6203*, Sieber, Agrostoth.

TasMANtA. New Norfolk, Gunn 996 p.p.; Mount Direction, 
Gunn; Latrobe River, Mueller ; Port Dalrymple, Paterson; and 
without precise locality, Llotsky; Gunn 588. 
Gunn 588 and Mount Direction have somewhat more acu- 
minate hyaline tips, but otherwise they agree well with S 
pubescens, R. Br. 
Under Gunn 996 there is a specimen dated 15.11.40, which 
agrees with another also by Gunn numbered 1453 and one by 
Llotsky, also from Tasmania, both having much stouter culms 
and broader leaf-blades than any of the specimens enumerated 
above. They are not S. pubinodis, Trin., and seem not to have 
been distinguished so far. They may represent a local race. 
Variation occurs also in the length of the awns. In the type 
(Brown 6203) they measure 6-7°5 cm. long, while in one of 
Llotsky’s specimens (without precise locality) they attain a 
length of ll em. This plant can hardly be called specifically 
distinct, as intergradations seem to exist between it and the 
type, so that I can only consider it as another example of a local 
variety or form.
