Fronds dwarf, filiform, creeping or erect, standing from basal 

 creeping portion where the plant adheres to other algae by emit- 

 ing root fibres from the under-surface, throughly ecorticated, alter- 

 nato-pinnately decompound, with patent or widely parted branches 

 densely arising near to each other. Longer shoots pinnately 

 branched in disticho-alternate manner with broader or slenderer, 

 shorter or longer laciniae, or with sooner or later limited similar- 

 ly pinnated short lateral branches. Laciniae grow together in 

 more or less congenital manner ; in adult ones each lacinia fur- 

 nished with isolated, well-defined single apical cell, while in younger 

 ones 2 or 3 apical cells are seen growing in a congenital manner 

 as shown in PL CXCVII, fig. 10 and older stunted branches on 

 the basal portion of frond is often much expanded with fiabellately 

 running midribs (fig. 12). Monosiphonous hairs entirely wanting.
