1898. J. H. Maiden, " Observations on the Vegetation of Lord Howe 

 Island," Proc. Linn. Soc. N.S.W. 23, 112. Mr. Maiden visited Lord Howe 

 Island in March-April, 1898, in H.M.C.S. " Thetis." His paper only enume- 

 rates those plants about which he has some information to add, besides 

 which he gives a list of introduced plants and some bibliographical notes. 

 (Altogether 100 species are dealt with, of which twenty are listed as intro- 

 duced, four could not be identified, four are Hemsley's names recommended 

 to be removed, three I consider to be introduced, and Asplenium Robinsoni 

 I treat as a form of A. nidus, thus leaving sixty-eight indigenous species, 

 of which eight are additions to Hemsley's list. Of Maiden's introduced 

 plants I include in my list as indigenous Bidens pilosa, Solanum aviculare, 

 and S. nigrum — this last an addition to Hemsley's list.)
