86 Transactions. 



Chile or Fuegia, two of them reaching the Falkland Islands. Four species 

 are Australasian, one being found in Victoria, another in Tasmania, and 

 two others (C. novae-zealandiae Hook. f. and C. ohtusa Cheesem.) in New 

 Zealand. Much information is afforded for the first time respecting the 

 degree of development of the leaf-auricles, and woodcuts are given of the 

 chief modifications, the leaves of both the New Zealand species being 

 figured. 



It is worth remarking that the section Psychrophila is one of those plant- 

 groups proving an alliance between the floras of Australia, New Zealand, 

 and South America. 



XVIII. Ehamnaceae. 



Pomaderris elliptica Lab. 



Kawliia district, growing luxuriantly on the fern-clad spurs and pro- 

 montories running down into the harbour ; Mr. E. H. Schnackenherg / An 

 extension of the southern range of this fine plant, the northern slopes of 

 Mount Pirongia being the previous known limit. 



XXII. Leguminosae. 

 Chordospartium Stevensoni Cheesem. 



Avon Valley, Marlborough ; H. F. Hursthouse ! This is a most inter- 

 esting discovery, the plant being previously known only from the original 

 habitat near the Clarence Bridge, South Marlborough, where it was collected 

 by Mr. George Stevenson in the summer of 1909. Mr. Hursthouse informs 

 me that in the Avon Valley it grows side by side with Notosjmrtnmi Car- 

 micJiaeliae, and that it is very difficult to distinguish the two in the absence 

 of fruit. He further remarks that when in bloom both are very beautiful 

 and striking plants, certain to attract notice even at a distance of half a 

 mile or more. 



Mr. Hursthouse has also favoured me with a large supply of the seeds 

 of Chordospartium. It seems to be difficult of germination, for out of 

 great numbers planted, both inside and outside New Zealand, only three 

 plants have been reared. 



XXVIII. Myrtaceae. . 

 Metrosideros Parkinsoni Buchanan. 



Abundant at the southern end of the Paparoa Range, near Greymouth. 

 Particularly plentiful on the steep slopes south and south-east of Mount 

 Sewell, and also on a spur running to the west of Mount Davy, alt. 2,000 ft. ; 

 P. G. Morgan ! The above are the most southern localities yet recorded 

 for this fine plant. 



I have also to record its discovery by Mr. W. R. B. Oliver on the summit 

 of Mount Hobson, Great Barrier Island, alt. 2,000 ft. The two specimens 

 kindly given to me by Mr. Oliver have rather narrower leaves than the 

 southern examples, and there are fewer flow^ers in the cymes, but otherwise 

 they entirely correspond. Its occurrence on the Great Barrier Island, 

 quite 350 miles in a straight line from the nearest of its southern habitats, 

 is a remarkable instance of discontinuous distribution, almost comparable 

 to the case of Pittosporum ohcordatum, where the only two localities 

 known — that of Kaitaia, in Mongonui County, and Akaroa, in Banks 

 Peninsula — are separated by 550 miles !
