 COMA. (Natural Order, Ficoide^:.) P. 30. — A trailing 

 or climbing perennial plant, with ovate or more frequently 

 rhomboid leaves. It is found in a wild state along the 

 coast, trailing over rocks, or ascending shrubs, which it 

 completely envelopes in a dense mass of leafage, the pendant 

 stems having in many instances a pretty effect, forming

 leaves and branches, afford a cool and pleasant retreat in hot

 it resembles the 'salt-bush,' and is therefore specially 

 desirable for sheep, preventing fluke, etc. It will thrive in 

 most arid regions. Tetragona expansa, although a native 

 of Australia and found along the north - eastern coast
