Fig. 330. ENTEROMORPHA COMPRESSA. 
Colour. A pleasant, bright grass-green ; fading pale, yellow, and white. 
Substance. Membranaceous ; thin. 
Character of Frond. Cylindrical or somewhat compressed ; occasionally thread-like {filamentous ') ; 
tubular ; more or less branched. Branches alternate ; widening gradually upwards ; 
blunt at the tips ; tapering to a mere thread at the base ; sometimes simple, some- 
times re-branched again and again. Occasionally contracted at intervals as if tied in. 
Tips blunt throughout. 
Measurement. From J of an inch to 12 inches long. Of every width from a hairshreadth to 
J of an inch. 
Fructification. As in the preceding. 
Habitat. On every coast everywhere. In brackish ditches also, and occasionally in inland 
waters. In a large sheet — almost a lake — in Clomber Park. Very common. 
Varying as this plant does in size, amount of branching, and hushiness, it may always be 
recognised among other Enteromorphas by the blunt tips and tapering bases of its branches. 
In one curious variety the stems are one-sixth of an inch wide, fringed all over with hair-hke 
bran chi ets. 
Fig. 331. ENTEROMORPHA LINKIANA. 
Colour. A very pale green. 
Substance. Membranaceous, but firm ; rigid when dry. 
Character of Frond. Thread-like [filamentous) ; cylindrical ; tubular ; inflated ; rising with a 
main stem, set with branches on every side. Branches long, slender, between erect 
and spreading, tapering to the tips ; re-branched with a second similar set, only finer ; 
these with a third, quite hair -like. Tips pointed throughout. 
Measurement. From 6 to 12 inches long. 
Fructification. As before. 
Habitat. Appin ; once found. 
The microscopic characters of this plant are very like those of E. claihrata^ E. erecta, and 
E. ramosa. The branches are wider, however, than those of E. clathrata, and it has not the 
thorny hranchlets of any of the three.
