AETEE A STOEM. 121 



Lami^aeia Phyllitis (Hart's-tongueLammaria). 

 — This is considered by some merely a variety of La- 

 minaria SaccJiarina; but the small size and delicate 

 substance render it a desirable specimen. It grows 

 on stones or on stems of the larger seaweed, and in 

 deep water ; so we are more likely to find it on the 

 beach after a storm. Sidmouth, Yarmouth, Dover, 

 Channel Islands, Ireland, Scotland. 



Laminaeia Fascia (Small-tufted Laminaria). — 

 On sand-covered rocks and stones, at lowest ebb of 

 the sea, this delicate species grows. Stem very short; 

 fronds either broadly oblong, wedge-shaped, or lanceo- 

 late; from four to twelve inches long, of a delicate 

 membranaceous substance and olive yellow hue. Plen- 

 tiful in the Channel Islands, St. Michael's Mount, 

 Sidmouth, Plymouth, north of Ireland, and western 

 islands of Scotland. 



Two other species of Laminaria may be found cast 

 up by the waves ; they are comparatively rare ; one is 



Lamlnaeia Longiceueis. — The frond has a re- 

 markably long stem, which is unlike every other in 

 being hollow ; often six or eight feet long and an inch 

 in diameter. It abounds in the Northern Ocean, 

 Newfoundland, Greenland ; but is washed ashore, and 

 should be examined for rare seaweeds, diatoms, and 

 .zoophytes. 



Lamlnaeia Cloustoeii. — This is almost as com- 

 mon on the Irish coast as Laminaria Digitata, but 

 rarely in England. It has a slender polished stem, a
