THE SEAWEEDS 
Dasyphloea tasmanica Harvey. 
Attachment discoid. Frond softly cartilaginous, rose red, decompound, 
much branched; branches irregularly inserted, repeatedly divided, nar- 
rowed towards each extremity and beset with small setaceous ramuli. Frond 
15 cm. to 25 cm. long, and as much in the expansion of the branches. 
The principal stem is either simple or divided into two or more branches, 
which are simple or forked. These throw off, laterally, numerous secondary, 
patent branches of unequal length, tapering at base and apex, flexuous and 
subacute; ultimate ramuli setaceous. Cystocarps formed two together in 
the ultimate ramuli, which then become fusiform. Adheres to paper. 
Victoria (Port Phillip), Tasmania.
