 (Tab. LXXXIII. Fig. 4.) 



Hab. Northern Island, Colenso. 



A small species not \ inch long, allied to F. viridulus, but differing in the very short cymbiform leaves 

 and in the habit of growth, which connects it closely with F.tamarindifolius, Smith. Male flower gemmiform at 

 base of the barren shoots. Fruit terminal.— It is found also at the Cape of Good Hope, and at Mendoza South
