is all the more excusable, as both species are often growing commixedly, 

 and as small form« of H. hyalospermum deceptively resemble H. Jesseni, 

 though the lalter does not seem to reach the extreme of south-westera 

 Australia, and is not contained in any of Drummond's collections ; 

 whereas it seems to preponderate over the genuine It. hyalospermum in 

 the south-eastern regions of Australia. The now separated species is 

 usually smaller in all its orgaus, the iuvoluere of the young headlet is 

 less turbinate and the lower bracts are generally laxer and less elongated, 

 the receptacle is less rough, the corollas are more dilated upwards, the 

 wellmatured achenes are rather less flattened and always without transparent 

 margin, so that the name hyalospermum would not so well apply, and 

 the pappus-bristlets are neither much dilated nor conspicuously connate 

 towaids the base. The aspect is much that of Myriocephalus yracilis t 

 while H. hyalospermum approaches in general appearance more to the- 

 small form of H. cotula. 



Specimens of H. Jesseni have been examined on this occasion froin 

 the following localities, irrespective of others, the collectors being also 

 indicated: — Gawler-River, Dr. B ehr; Wirrabara, Gill; Lake Alexandrina, 

 Murray-River, Burra-Burra, Wimmera, Murumbidgee, F. v. M. ; Richardson- 

 River, Dr. Cur die; Edwards-River, Dr. Mein; Lachlan-River, Brueckner; 

 Darling-River, Wuerfel; Cobar, Andrae; Wagga -Wagga, Hammond; 

 Mount Murchison, Bonney; Caiwarra, Mrs. Cotter; Barrier-Ranges, 



E. Wehl; Lake Cobham, Baeuerlen; Bulloo and Paroo, L. Morton; 

 Ballandool-River, Locker; apex of St. Vincent's Gulf, Mrs. Matthiesen; 

 Port Augusta, Mrs. Richards; Port Lincoln, J. S. Brown; Upper 

 Spencer's Gulf, Felstead; Port Gregory, Oldfield. 



Carefully compared have been now also, from the largely accumulated 

 material of later gains. numerous samples of H. hyalospermum, thus from 

 the undermentioned places : — Gawler- and Murray-River, Murrumbidgee, 



F. v. M. ; Edwards-River, Miss Kuentz; Yorke's Peninsula, Miss Salmon; 

 Lake Gilles, Burkitt; Fowler's-Bay, Mrs. Richards ; west end of Great 

 Bight, C a r e y ; Mount Rugged, Miss. B r o o k e s ; Stirling-Range, F. v. M. ; 

 Swan- River, Drummond and Preiss; Irvin-River, Miss Guerin; Port 

 Gregory, Spalding; Bowes- and Murchison-River, Oldfield. No transits 

 have been found between these two species in all the dissections in- 

 stituted. 



Helipterum Jesseni is the seventeenth plant, wich among vasculares 

 has been added to the records of species, indigenous to this colony, since 

 two years ago the „Key to the System of Victorian Plants" was issued. 

 The others are: — Clematis glycinoides, Kochia aphylla, Eucalyptus Muelleri, 

 Cryptandra spatulata, Aster Frostii, A. picridifolius, Quinetia Urvillei, Heli- 

 chrysum Stirlinyi, Helipterum laeve, Calocephalus Drummondi, Erechtites 

 mixta, Caladenia Cairnsiajia, Dralcaea irritabilis, Corysanthes unyuiculata, 

 Prasophyllum Frenchii, Cystopleris fragilis.]
