Flowers smaller; styles 3. Drupe small, globose, fleshy, bright-red, \ in. 
diam. 
Northern Island: east coast, Banks and Solander. Sand-hills, Cape Turuagain, 
Colenso. Auckland, Sinclair. In the dried state it is difficult to distinguish this from 
T. expansa, but the figure in the Banksian collection represents a very different plant, of 
smaller size, with rounder leaves, and with unarmed and fleshy drupes.
