Fig. 215. KALLYMENIA RENIFORMIS. 
Colour. A fine, deep crimson. 
Substance. Fleshy-membranaceous. Soft and tliickish when fresh ; becoming thinner in 
drying. Stems gristly. 
Character of Frond. Eoundish or kidney-shaped (broader than long) expansions, suddenly 
spreading from a very short, cylindrical, simple, or branched stem. Expansions very 
irregular in shape and size ; either quite simple or bearing along their margin 
frondlets of a similar character, and often bigger than the original one. Margins 
smooth, except when torn ; rarely, waved. Root a disc. 
Measurement. From 1 to even 14 inches in diameter. 
Fructification. Of two kinds. 1. Round clusters of spores half immersed in, and scattered 
over the frond. 2. Tetraspores very minute ; imbedded in the same. , Fruiting in 
winter. 
Habitat. The warmer stations on our coasts. Isle of Wight ; Scilly Isles ; &c. The 
Orkney Islands (probably owing to Gulf-stream influence). Kilkee. In deep shady 
pools at extreme low-water mark. Rare. 
The small form {K. microphylla of Agardh), exactly corresponding to the figure in English 
botany, is frequently cast ashore in winter-time, in Niton Bay, Isle of Wight. In this variety, 
the sturdy little stems generally give out several fronds ; and the spore-groups are very large 
in proportion to the size of the plant. Two small lobes in the upper part of the present 
figure represent this. The larger sort needs more G-ulf-stream warmth, than the Isle of Wight 
can boast of. Specimens from Kilkee would make a dozen of the Niton winter variety.
