KiBK. — 071 the Botany of the East Cape District. 515 



and the low-lying Mahia Peninsula are examined in detail, the 

 number of species will probably be raised to six hundred and 

 fifty or seven hundred, the additions consisting almost ex- 

 clusively of flowering-plants. 



A few plants of considerable interest are endemic in the 

 district, — 



Carmichaelia williamsii, T. Kirk. 



Coprosma solandri, n.s. 



SeDecio perdicioides, Hook. f. 



Peperomia muricatulata, Col. 



Peperomia reflexa, Dietrich. 

 The last, however, has a wide distribution outside New 

 Zealand. 



Senecio banksii, Hook. f. 

 This is also known to occur on the Mokohinou Islands, 

 but not elsewhere. 



But the chief interest of the district arises from its exhibit- 

 ing such a remarkable intermixture of plants characteristic of 

 the extreme north of the colony with others of a peculiarly 

 southern type. Nowhere else do we find associated genera 

 offering such a remarkable contrast when considered with 

 regard to their geographical distribution as Pisonia and Eu- 

 phrasia, Sideroxylon and Aciphylla, Persoonia and Gentiana, 

 Vitex and Calceolaria ; while the number of species that attain 

 their northern or southern limits within its boundaries is per- 

 haps larger than could be found in any other district of 

 similar area in the North Island, as will be seen from the 

 following list : —
