Tasmanian plant the name H. Banksii, the former specific appella^ 

 tions H. angustifolia and H. dentata were abandoned as carrying no 

 longer any significance with them, since it was moreover proved 

 (Plants of "Victoria, i. p. 70) that the form of the leaves is not even 

 available for a precise distinction between H. Banksii and H. latifolia. 

 In all probability only one species of this genus exists, for which the 

 collective name H. Banksii might well be retained. R Brown, when 

 establishing the genus in his learned memoir on the Congo plants 

 (Append, to Tuckey's Narrative of an Expedition to the River Zaire, 

 p. 442), attributes to it the exceptional ordinal character of a two- 

 celled berry ; all fruits, however, examined on this occasion, even in 

 a very young state, proved one-celled.

The specimina are in fruit; these, the leaves and calyces are 

 larger than those of the New Zealandian specimina of our museum. 



From various parts of New Zealand our collection possesses plants 

 of Plagianthus Lyallii (Asa Gray, Botany of Unit. States Explor. 

 Expedition, 181), although only in a flowering state. These show 

 the number of styles to be variable from 10 to 15 (10, 11, 13, 15),
