THE SEAWEEDS 
cortex, subverticillate, monosiphonous from the base, branching densely 
into smaller ramelli, which are dichotomous. Stichidia oval, mucronate. 
Cystocarps below the apices of the inflated pinnellae, globose, rostrate. 
Victoria, Tasmania. 
Dasya Clift oni Harvey. 
Stem long, slender, flexuous or spiral, glabrous, inarticulate, sub- 
distichously branched, bi-tripinnate ; pinnae patent, glabrous; pinnules 
alternate, subdistant, ramellif erous ; ramelli divaricately much branched, 
dichotomous, scarcely attenuate, obtuse, their articulations three to four 
times longer than broad. Stichidia lanceolate. 
Attachment or holdfast discoid. Fronds densely tufted and rarely 
extricable, 25 cm. or more in length, less than 1 mm. thick, gradually 
attenuated upwards, subdistichously bi-tripinnate. The main stem and 
primary branches are everywhere inarticulate, being coated externally with 
a layer of slender, cylindrical, longitudinal, parallel cellules, and are 
glabrous or bare of ramelli; the penultimate branchlets or pinnules are 
alone ramelliferous. These are from a quarter to half an inch in length, 
and densely clothed on all sides with dichotomous ramelli, which are
