Coprosma, which forms so large a portion of the shrubby vegetation of 

 this colony is but sparingly represented in Australia, two species are 

 common to both countries, one of them however only occurring in Lord 

 Howe's Island, on the Australian side. A species of Nertera is common to 

 both countries. 



CompositcB, the largest order of Phmiogams, is less developed in Australia 

 than might be expected ; it comprises over five hundred species ; in New 

 Zealand it contains one hundred and fifty-five — nineteen genera and twenty 

 species only are common to both countries ; one-third of these are plants of 

 wide distribution, and ten are not found elsewhere. Celmisia, a fine genus 

 of mountain asters containing about thirty species, is restricted to New 

 Zealand, with the exception of C. longifoUa, which extends to the Australian 

 mountains. Olearia, another large genus restricted to Australia and New 

 Zealand, contains sixty-five species in the former country, and nearly thirty 

 in the latter, but no form is common to both. Brachycome is restricted to 

 these countries, but has no common species, and is most highly developed 

 in Australia. The important genus Senecio, which is largely developed ia 

 both countries, has only one common species. 



The remarkable Australian genus Stylidium is not represented in New 

 Zealand. Donatia novcB-zealandics is common to both countries, and Forstera 

 is represented in each by endemic species. 



Of Heaths and Epacrids, eight genera and seven species, none of which 

 are found elsewhere, are common to both countries. 



A single olive is found in Austraha, but does not belong to the section of 

 the genus which comprises the New Zealand species. 



* Of Scrophularinese, Australia has thirty genera and over one hundred 

 species. New Zealand has ten genera and sixty species, eight genera and 

 nine species being common to both countries, but not found elsewhere. 

 Veronica is represented by fifteen species in Australia, and forty-eight 

 here ; one of the Australian species belongs to the section with appressed 

 imbricating leaves. 



Nesodaplme, which enters so largely into the composition of the northern 

 forests in this colony, is represented in tropical Australia by a single endemic 

 species. 



Tetranthera, Atherosperma and Hedycarya, are represented in both coun- 

 tries, but have no common species. 



Proteace£e stand next to Myrtacese with regard to their influence on the 

 Australian flora ; but of the six hundred species known to occur there, not 



* I should perhaps mention the recent discovery in this colony of Liparophyllum, a 

 monotypic genus of Menyanthecs, hitherto supposed to be restricted to alpine lakes in 

 Tasmania, but the identification rests at present upon fruited specimens only*
