 The above specimens have been variously included under P. 

 prolutum F.v.M., but are separable from that species by the 

 narrower leaves and more spreading panicle. — P. prolifemm Lam., 

 Coolabah(R. N. Peaccck; June, 1900); Lachlan River (W. S. 

 Campbell; March, 1901); Zara, via Hay, (Miss E. Officer; Feb- 

 ruary, 1904); Hawkesbury Agricultural College (W. M. Carne; 

 March, 1909); Botanic Gardens, Sydney (W. F. Blakely; March, 

 1913). — P. notochthonum Domin. Specimens of this species, in 

 the National Herbarium, are from Yandama (A. W. Muller; 

 April, 1906); Tongo Station, Wilcannia, ( W. J. Hourigan; Jan- 

 uary, 1912); Girilambone (Grigg; April, 1913). Domin points 

 out that this is P. helopus of Bentham's Fl. Aust.(vii., 476), but 

 not of Trinerius. It is also quite distinct from P. helopus var. 

 glabrior of Bentham. — P. Buncei F.v.M., Darling Downs (Dr. 

 Woolls); Breeza(W. Court; May, 1899); Moree (Max Farland;

 and Moree (E. Breakwell; June, 1912); Gular(W. D. Brown; 

 June, 1913); Narandera (Stock Inspector; April, 1913). This 

 species has previously been included under P. trachyrhachis var. 

 tenuior Benth., but, as pointed out by Domin, it is quite distinct 

 from that variety, and P. trachyrhachis of North Australia is 

 also quite distinct from this series. — P. strictum R.Br., Blue 

 Mountains (E. Betche; December, 1882); Randwick (E. Betche,
