It is very questionable whether this plant has been found 

 in New Zealand. Specimens from New Zealand thus named 

 have, according to x\gardh, been generally, • perhaps always, 

 varieties of the preceding (De Alg. N.Z. mar., p. 7).

I obtained specimens of this plant apparently from the 

 same tidal pools from which Berggren obtained it. I append 

 a description which will probably be sufficient for systematic 

 purposes (Agardh's specimen did not include rhizoid or 

 bladders) : C. angustifolium, rhizoid, matted, fibrous, consisting 

 of a mass of anastomosing hapteres, which are expanded at their 

 terminations, and closely appressed to the surface of the rock, 

 forming a disc-like structure ; frequently enclosing numerous 

 pebbles, shells, and other extraneous material. From this 

 disc are derived a large number of pendulous fiexuous stems, 

 80-150 cm. in length and 1-2 mm. broad.''' This breadth 

 remains constant throughout the whole length, with only a 

 slight tapering at the tips. In transverse section the stem is 

 oval. At distances of from 3-4 cm. short pinnate branches of 



* These measurements and the general description apply to the dried 

 specimen only.
