Fig. 215. KALLYMENIA EENIFORMIS. 



Colour. A fine^, deep crimson. 



Substance. Fleshy-membranaceous. Soft and thickish when fresli; becoming 

 thinner in drying. Stems gristly. 



Character of Frond. Roundish or kidney-shaped (broader than long) expan- 

 sions, suddenly spreading from a very short, cylindrical, simple, or 

 branched stem. Expansions very irregular in shape and size; either 

 quite simj)le or bearing along their margin frondlets of a similar char- 

 acter, 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. Tetrasi:)ores 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. micropliylla 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 jDroportion to the 

 size of the plant. Two small lobes in the upper part of the present figure 

 represent this. The larger sort needs more Gulf-stream warmth than the Isle 

 of Wight can boast of. Specimens from Kilkee would make a dozen of the 

 Niton winter variety.
