430 THE BOTANY OF [PART II. 



which are quite peculiar to New Zealand; these are Ed- 

 wardsia, Clianthus, and Carmichaelia. 



The family of the Rhamnece has the genera Cardopetus, 

 Pennantia, Pomaderris, Corokia, Ixerba. 



That of the Coriariea the Coriaria sarmentosa, a very 

 common shrub, the leaves of which contain an acrid poison, 

 and often produce violent symptoms if eaten by cattle. 



The family of the Rutacea has the genus Melicope (2 

 species). 



Of Euphorbiacece, the Euphorbia glauca grows amongst 

 the shingle of the sea- shore and on barren hills. 



Of Santalacea, the genus Myda is represented by three 

 species. 



Amongst the Thymelceai, Jussieu, the genus Pimelea has 

 six species, mostly shrubs. 



Of the Proteacece, the Tora (Persoonia tora) and Rewa- 

 rewa (Knightia excelsa) are the only known species. The 

 latter yields a very beautiful wood, and with its dark-purple 

 flowers would be a very ornamental tree. It is the New 

 Zealand representative of the Banksias, of which such a 

 variety of species are known in New South Wales. 



To the Laurinece belong two trees, which are very com- 

 mon in some parts of the island. The Laurus tarairi 

 and calicaris are especially found to the northward, around 

 Waimate and Kaitaia, where they form groves on the banks 

 of rivers. The Laurus tawa covers the upper regions of dry 

 hills in Cook's Straits, especially on the Tararua mountains 

 at Port Nicholson, where it forms continuous forests. 



Of the Atherospermece, the Laurelia Nov. Zeland. grows 

 likewise in the northern island, forming a moderate tree. 



Of the Polygonece we have the genera Polygonum (3) and 

 Rumex ("2). 



Of the Chenopodieee the genera Chenopodium (1) and 

 Salicornia (1). 



Of Amaranthacece~\he Alternant hia denticulata. 

 Of Peronychicce the Mniarum biflorum. 

 Of Plantagineai the Plantago major and varia. 

 Of Primulacece the Anagallis arvensis and Samolus 

 litoralis.
