globose, as large as peas, 3 or more borne on short, filiform petioles toward 
the base of the primary pinne.  Aeceptacles formed out of all the pinnules 
indiscriminately, 5-1 inch long, strongly constricted into bead-like pseudo- 
Joints, each containing a scaphidium, and usually terminated with a seta- 
ceous point. Colour dark-olive, becoming black in the herbarium. Swé- 
stance coriaceous, tough.

This is allied to C. retrofleva (Fucus retroflecus, Labill. t. 260, 
not of Turner), from which it is easily distinguished by the mo- 
niliform receptacles and the nearly-globose vesicles. In C. refro- 
flexa the receptacles are sword-shaped, evidently compressed, and 
much less torulose than is usual in the genus. Both species 
seem to be equally common, and are distributed along the same 
coasts, extending to New Zealand.
