CHLANIDOTE J. Agardh. 
There is but one species, found in South Australia and Victoria. 
Chlanidote micropliylla (ITarv.) J. Agardh. 
Frond erect, dendroid, with a stout stipes (to 6 mm. in diameter), 
branched on all sides. The stipes is coated with foxy curled hairs. The 
branches break up into very numerous flabellulate, lacerate glabrous 
segments. These segments or laciniae are very narrow, the terminal ones 
truncate, the lateral subulate acute. Oogonia single, scattered near the 
margin, obovate-globose ; antheridia (?) in the same individuals form 
oblong-linear sori directed longitudinally on the frond, dividing at length 
into sets of 4 cells. Height of plant 7.5 to 15 cm. Colour dark-brown. 
LOBOPHORA J. Agardh. 
Lobophora nigrescens J. Agardh. 
With one species only, gathered by J. Braceb ridge Wilson at Dromana 
in Port Phillip. 
Frond flat, ribless, flabellate, sub-lamellate with similar lobes prolificating 
from the upper surface. 
TAONIA J. Agardh. 
Frond erect, flat, ribless, splitting into palmatifid or subdichotomous 
laciniae ; constituted of two strata of rectangular cells, the inner consisting 
of usually 4 layers, the outer of a layer of densely coloured small cells. 
Oogonia, antheridia, tetraspores all in different individuals, the oogonia in 
scattered sori, the antheridia also in sori, the tetraspores (sporangia) 
approximate in concentric flexuose lines. 
Taonia australasica (Sond.) J. Agardh. 
Frond irregularly split into lobes, to 15 cm. high, fenestrated with 
rectangular areas between thick cross bars. Colour a yellowish green. 
South Australia and Victoria. 
PADINA Adanson. 
Fan-shaped fronds, entire or split into sections, membranaceous, often 
cucullate, concentrically zoned. Thallus of two strata of rectangular cells, 
the inner consisting of two or more layers of parallelepipedal cells, the 
outer of a single layer of coloured cells. Oogonia and antheridia on the 
same plant, tetraspores on separate plants; oogonia in sori of few large 
cells, antheridia in sori of many large cells, tetraspores scattered along 
the margins of the zones. Often indehiscent.
