Zealand : No. 3. 



By T. F. Cheeseman, F.L.S., F.Z.S., Curator of the Auckland Museum. 



^Bead before the Auckland Institute, 22nd Noiember, 1909.] 



As in the tM^o previous instalments of notes bearing this title (see Trans. 

 N.Z. Inst., vol. xxxix, p. 439 ; vol. xl, p. 271), I have to acknowledge my 

 indebtedness to many friends and correspondents in various parts of the 

 Dominion for much of the matter now placed on record. I particularly 

 desire to mention my obligations to the late Mr. H. J. Matthews, whose 

 position as head of the Forestry Department gave him many opportunities 

 of obtaining information respecting the New Zealand flora, and who for 

 years past has liberally supplied me with specimens, notes, and photo- 

 graphs. His decease will be greatly regretted by New Zealand botanists, 

 by whom he was held in high esteem, not only for his many services to 

 botanical science, but also for his amiable and genial disposition, the sim- 

 plicity of his manners, and his truly lovable character. 



I have also to express my thanks to the following gentlemen : to Mr. 

 F. G. Gibbs, of Nelson, who has forwarded many interesting notes and 

 specimens, mostly dealing with the botany of the north-western portion 

 of the Nelson District ; to Mr. B. C. Aston, of Wellington, for many speci- 

 mens collected through almost the whole length of the Dominion ; to Mr. 

 K. H. Matthews, of Kaitaia ; to Messrs. H. Carse, P. H. Allen, A. AlUson, 

 Eev. F. R. Spencer, F. N. R. Downard, J. H. Harvey, G. Williams, 

 W. Townson, R. Mair, E. Linton, E. Clarke, C. Dawes, and others.

Mr. W. B. Hemsley (" Kew Bulletin," 1908, p. 95) has pointed out that 

 the New Zealand plant referred by Kirk and myself to the Norfolk Island 

 H. latifolia is in reality distinct from that species. He states that the 

 Norfolk Island plant has relatively more slender branches, thin entire leaves, 

 smaller flowers, and the staminal appendages are only fringed at the tips 

 instead of being minutely toothed all round the margin. Mr. Hemsley has 

 also satisfied himself that Cunningham's Sccevola novce-zealandics, collected 

 at Matauri Bay, opposite the Cavallos Islands, and which Hooker refen-ed
