PLANTS OF THE CHATHAM-ISLANDS. 



VIOLACE^. 



Hymenanthera latifolia. 



Endl. Prodrom. Flor. Insul. Norfolk. 71 ; Endl. leonograpli. Gener. Plant. 108. 



Varietas Chathamica; leaves serrulate. 



Rare in woods. 



The specimina brought by Mr. Travers are fruit-bearing and 

 respond fully to Endlicher's description and Bauer's illustration, with 

 exception of the margin of the leaves, which is toothed by short 

 regular notches. The stipules, overlooked in the plant of Norfolk- 

 Island, and also by some describers of the Australian species, are 

 akin to those of H. Banksii, although proportionately larger. The 

 plant from Norfolk-Island and Chatham-Island may exhibit merely 

 a luxurious variety of the Australian species. The embryo of the 

 Chathamian plant agrees in its characters entirely with the united 

 Australian and Tasmanian species ; the cotyledons being orbicular, 

 not narrow as (probably from a side view of those of H. crassifolia 

 in Fitch's Illustration, vii. of J. Hook. Fl. Nov. Zeal.) recorded in 

 Benth. and J. Hook, admirable Genera Plantarum, i. p. 120, and 

 Benth. Flor. Austr. i. 104. Having had only an opportunity of 

 examining flowering specimens of the New Zealandian congener, 

 which in no respect differ from certain especially alpine states of H. 

 Banksii, the author must leave it for future observers to ascertain 

 whether in reality H. crassifolia can be distinguished by the narrow- 

 ness of its cotyledons. In adopting for the combined Australian and
