species in the Kew Herbarium serves to confirai that view. P. villosi- 

 fiorus being the carlier Dame, must be kept up. 



Ptilotus Sewelliee, F. v. M, in « Yict, Nat, Jan. 1885 ». ex F. v. M. 

 Census, 48 (1889). 



= Trichinium Rœi, Bentli. Flor. Austr.. Y. 240 (1870). 



P. Sewelliée is a « nomen nudum » ; I have searched in vain in diffé- 

 rent publications for a description of it but a spécimen of Mueller's 

 bearing the name in the Kew Herbarium is identical with 

 T. Rœi. 



Trichinium siphonandrum,Diels in Engl. Jahrb., XXXV, 189 (1905). 

 = Trichinium auriculifolium, A. Cunn. 



Reasons for this réduction are given in the body of the paper. 



Ptilotrichum capitatum, F. v. M. Frag.. I. 238 (1858). 



== Ptilotus psilotrichoides, F. v. M. Frag., XI, 97 (1878-1881). 



Ptilotus Macleayi, F. v. M. in Proc. Linn. Soc. ]S T . S. W. sec. ser., 

 III. 162(1885). 



= Ptilotus psilotrichoides, F. v. M. Frag., XI, 97 (1878-1881). 



Ptilotus psilotrichoides, F. v. M. Census, 29 (1881). 



= Trichinium corymbosum. Gaud. et Ptilotus psilotrichoides, 

 F. v. M. Frag., XI, 97 (1878-1881). 



These three réductions concern a plant which is of some historié inte- 

 rest, as it is the only described Amaranth which is left unplaced in the 

 Flora Australiensis (Vol. v., p. 209 (1870). The reasons for the réduc- 

 tion of Psïlotrichum capitatum are given incidentally in the body of the 

 paper. As to Ptilotus Macleayii, it is the same plant Mueller had descri- 

 bed on two previous occasions and which Bentham had failed to place. 

 It remains to be added that in his Census, evidently by a clérical error, 

 Ptilotus psilotrichoides is confounded with his Hemisteirns psilotrichoi- 

 des, that is Trichinium corymbosum. a totally distinct plant. This inte- 

 resting plant, Ptilotus psilotrichoides, is only recorded from the Kim- 

 berley Division. 



The number of new species described below amounts to seven. The 

 woi'k bas been made somewhat difficult by reason of the very scanty 

 herbarium material of some of the old species. 



I am much indebted to Dr. Stapf for advice on some critical points.
