a more successful utilization is possible, e.g. in New Zealand (Fig. 13).
Frond injury, such as may occur aa a result of the browsing activity of
animals, results in new apical cells being formed from existing cells oi
the cortex, and these bring about the growth of new branches. The
structural features of the other Pterocludiu species have been reported
by Fan (1961).
FIQ. 13. Pterocladia Zucida; drift specimen from New Zealand. (Scale line = 16 om).
9. Suhria
Suhrh vattata is a, potential agarophyte growing on the coast of
South Africa. The plants have a ribbon-like form of frond with a
fringed margin and a distinct midrib. It usually grows as an epiphyte,
so that the attaching system is a small discoid structure. The basic
features of thallus construction are the same as those described for
Qelidiurn and Pterocladia, with medullary and cortical regions to the
frond containing downgrowing hyphae. The profuse growth of these
