410 DICOTYLEDONS AND CONIFERS 



CRASSULACE^ 



Tilleea trichotoma, Walp. 



First recorded in 1882 by Cheeseman as "growing on the sides 

 of the road near Penrose (Auckland), and spreading rapidly on the 

 lava-fields around Mount Stuart." Also reported from Wanganui by 

 E. W. Andrews. In 1915 Carse reports it as found near Kaitaia 

 by H. B. Matthews. (Fl., Sept. to Oct.) 



Sedum acre, Linn. Biting Stonecrop ; Wall-pepper 



Recorded by W. W. Smith in 1903 as occurring in the Ashburton 

 County; apparently introduced in unclean seed, and spreading on 

 farms. A. H. Cockayne states that there are miles of it in some of 

 the Canterbury river beds.. Dr Cockayne says it is increasing in dry 

 parts of the South Island. 



MYRTACE^ 



Eucalyptus amygdalina, Labill. " Stringy-bark' of New South Wales ; 

 "Peppermint-tree" of Victoria and Tasmania 



Maxwell reports this as spreading in Taranaki. 

 It is one of the species which suffered from Eriococcus in South 

 Canterbury in 1900. 



Eucalyptus regnans, F. v. M. 



Simmonds reports this as spreading in the North Island. Also 

 suffered from scale in 1900. 



Eucalyptus coccifera, Hook. 



Badly attacked by Eriococcus in 1900. I do not know whether or 

 not this species has spread naturally. 



Eucalyptus radiata, Sieb. {E. numerosa, Maiden) 



At Waitati, near Dunedin, this species seeded into ground which 

 had been covered with manuka and burned. Numerous self-sown 

 trees sprung up, which in 1913 were 28 to 29 inches in diameter. 



Eucalyptus obliqua, Lher. "Stringy-bark" of Victoria, 

 South AustraUa and Tasmania 



This species spreads from plantations about Auckland (Simmonds), 

 and Taranaki (Maxwell).
