Loose form: f. fenuior Lyngbye Tent. Hydr. 1819, p. 42. 
In the inner Danish waters, in sheltered localities a loose form frequently 
occurs, in particular in the Zostera-formation, entangled among the rhizomes together 
with other loose Alga. It is well described by LyNGByE under the above name, 
and authentic specimens collected at Hofmansgave by LYNGBYE are to be found in 
the herbarium of the Botanical Museum at Copenhagen. It is characterized by small 
dimensions (about 1—2 cm in diameter) and by the thin dichotomous frond with 
divaricate branches. It often forms irregular clumps with the branches pointing in 
all directions. It propagates by vegetative division, the frond by degrees dying away 
at the base during continued dichotomizing at the top (fig. 563 bis).
