Hab. East Coast, rare, Colenso. 



We have not seen the creeping stems. Our specimens consist of branches, 4-5 inches long, twice as thick as 

 hog's-bristle, simple or forked, regularly articulato-constricted at intervals of one or two lines, clothed with leaf- 

 like ramuli throughout. Hamuli opposite, distichous, two springing from above the middle of each internode, half 

 an inch long, cylindrical, obtuse, very much constricted at their insertion, as thick as the branches, bright green. A 

 distinct and beautiful species.
