Australia : Lord Howe Island, C. Moore, 24, 45. 



At the request of Mr. J. H. Maiden, the Director of the Sydney 

 Botanic Garden, the writer made a critical comparison of the Lord Howe 

 Island specimens, described above, with mainland specimens referred 

 by Bentham (Fl. Austral, vol. i. pp. 381-2) to Dysoxylum Fraseranum, 

 Benth., and D. Lessertianum, Benth. {Hartigsea, A. Juss.), with the 

 result that they proved to be quite distinct. Further, as suggested by 

 Dr. Stapf, the specimens in the Kew Herbarium bearing these two names 

 belong to one species. It is probable that the inflorescence of the Lord 

 Howe Island plant is sometimes longer than in the Kew specimens, 

 as Moore has a note to tlie effect thnt the fruit is produced on long 

 panicles, — W. Botting Hfmsley.
