Khodymenia Jubata. — The frond is dull red, 

 turning to orange or olive green at the tips, and edged 

 with cilia ; sometimes densely covered with long red 

 filaments, from three to six inches long or more, which 

 clasp round each other and the neighbouring plants 

 in a very entangled mass. It varies in growth ex- 

 tremely : sometimes the whole frond, instead of its 

 usual fiat form, becomes cylindrical and excessively 

 branched, beset with horn-like ramidi. The fruit is 

 either a terry or coccidia, containing small spores on 

 a central placenta, or tetraspores imbedded in the 

 surface of the frond. 



Frequently cast up after a storm on all our coasts, 

 and in the Channel Islands we gather splendid speci- 

 mens at vraicking-time on roots of Laminaria, which 

 are cut away from the rocks beyond tide mark. 



Rhodymenia Bifida. — Cast ashore on our island 

 coast, but is a native of the deep Atlantic and the 

 Mediterranean Sea. "We recognize it by its thin, deli- 

 cate rosy frond, much divided, the margin sometimes 

 lightly fringed and dotted with sori. It is, never- 

 theless, a varible plant, not always easy to make out 

 more than that it is a Rhodymenia. The frond is 

 sometimes narrow, and dries a dark brown ; at other 

 times fan-like, with broad segments, and beautifully 

 pink. 



Rhodymenia Lacenata. — On Laminaria stems 

 and rocks beyond the tide. Cast up by the troubled 

 waves, this splendid seaweed is a prize. The broad, 

 bright red frond spreads over the page of our album,
