Cahsk. — -Flora of the Mangonui Covnty. 207 



of this district represent one-third of the total number for the Dominion. 

 I think, when we consider how rich and varied is the phmt covering of the 

 South Island when compared with that of the North Island, we may conclude 

 that 538 species is " not so bad." 



Of the 97 natural orders of plants known in New Zealand 86 are found 

 in this district, divided into 251 genera. 



Of the 86 orders, the largest are Filices, with 99 species ; Cyperaceae, 51 ; 

 Orchidaceae, 35 ; Gramineae, 31 ; Compositae, 30 ; Rubiaceae, 21 ; Myrtaceae 

 and Liliaceae, 14 each. 



Of the genera, the largest are Coprosma, with 16 species ; Carex, 14 ; 

 Pittosporum and Hymenophyllum, 10 each ; Lomaria and Polypodium, 9 

 each ; Epilohium, Asplenium, and Juncus, 8 each ; Metrosideros, Scirpus, 

 and Cladimn'7 each.
