Colour. A dull red ; becoming pale and yellow when old. 
Substance. Fleshy-membranaceous ; feeling like soft, wet kid-leather. 
Character of Frond. A flat, ribless, leafy expansion, rising wedge-wise, from a very short, 
compressed stem. Outline pear or wedge-shaped. At first quite simple ; after- 
wards apt to be torn and divided ; probably by the waves. Margins sometimes 
wavy. Foot a disc. 
Measurement. From 6 to 12 inches long. 
Fructification. Only one kind observed. Found clusters of spores half-immersed in, and 
scattered over, the frond. 
Habitat. South of England, and west and south of Ireland ; Scilly. On rocks and stones 
between tide-marks in land-locked bays. Not common.

Substance. Fleshy ; gristly ; almost leathery ; firmly elastic. 
Character of Frond. A flat, ribless, leafy expansion, rising gradually from a short, taper 
stem. Several from one root. Outline pear-shaped. Always quite simple, but 
often torn by the waves, as well as eaten into holes by sea-worms. Margins smooth 
and even. Foot a large, expanded disc. 
Measurement. From 4 to 18 inches long ; from 2 to 8 wide. 
Fructification. Of two kinds. 1. Found clusters of spores half immersed in, and scattered 
over, the frond. 2. Tetraspores in oblong groups {sori) also immersed and scattered. 
Both showing like dark spots when the plant is held up to the light.
