Litoral and sublitoral. It often grows in rock-pools in 

 the lower part of the litoral zone, but here it mostly gets 

 rather dwarfed. It is best developed in the upper part of 

 the sublitoral zone, on a depth of 1 — 8 fathoms, and here I 

 have seen specimens which had a length of 1 m. and more. 

 A young specimen taken on a depth of 5 — 8 fathoms has a 

 proportionally broad lamina. 1 The stipe of it is 8 cm. long, 

 bearing a few very young (2 mm. long) sporophylls. The
