Fig. 35. PADINA PAVONIA. 
Colour. Olive-green shaded with rust colour ; striped with lines across ; some of these fringed 
with orange-coloured hairs ; others dark. Outer surface powdered with white. 
Substance. Leathery and opaque below ; above, delicately membranaceous and transparent. 
Character of Frond. A fan-like, semi-circular expansion ; rihless ; entire or slit into segments ; 
each becoming fan-shaped in time. Margins rolled backwards ; sometimes fringed 
with hairs. When young, growing in a curled, rolled-up manner (see figure). When 
old, expanded. Boot woolly. 
Measurement. From 2 to 5 or 6 inches high. 
Fructification. Minute seeds {spores) on the upper surface of the frond, lying in bands across 
it ; in fact, forming the darker striped lines described above. 
Habitat. Southern shores of England. On rocks in shallow tide-pools at half-tide level. 
Bare. 
A beautiful plant, supposed to resemble an outspread peacock’s tail. The iridescent tints 
which its lines fringed with hairs give out in the water, assist this idea, suggested originally 
by its shape.

across ; some scattered irregularly between.
