Frond 25 cm. to 40 cm. high, almost pyramidal; ramuli almost regular, 
alternately pinnate; pinnae spreading from the rachis, linear-lanceolate, 
ancipitous, singly or covered with another row of pinnellae, all very fusi- 
form, the last carrying fruit. Tetrasporangia in the upper part of the 
lesser pinnulae. Cystocarps on the edges of the pinnulae, singly or in 
groups. 
South Coast of Australia. 
Chondria ovalifolia J. Agardh. 
Fronds 15 cm. to 25 cm. long, ancipitous, spreading widely and evenly 
from the edge of the stem; sometimes alternate, at other times almost 
opposite, branching off close to the main stem; smaller ramelli oval, and 
larger ones ovate-oblong, all very obtuse and constricted at the base almost 
into petioles ; cortical cellules ovate-oblong. Colour purplish-red. Adheres 
to paper closely. 
Victoria (Port Phililp). 
Chondria Curdieana Harvey. 
Fronds paniculate, irregularly pinnat^ly branched, ramuli close together, 
fascicled ; the ramelli pyriform, clavate, depressed and tufted above, curving 
to the apices ; numerous ramelli emitted from the inner side of the curve, 
and forming a second set of ramelli. Stichidia regular, carrying tetraspores 
on the tufted upper parts of the adult frond. Substance cartilaginous, 
adheres to paper. 
South Coast of Australia. 
Chondria sncculenta (J. Ag.) Falkenberg. 
Frond 15 cm. to 20 cm. long, terete, sometimes paniculate, at other times 
fascicled, ramuli and ramelli rising from the cylindrical rachis singly and 
very attenuated, the younger ramelli elliptical, adult ramuli cylindrical- 
oblong; slightly tufted. Stichidia tufted and carrying tetrasporangia, with 
prominent obtuse apices. Cystocarps large, almost globose, shortly pedi- 
cellate, carried in the apices of the ramelli. Substance gelatinous, adheres 
to paper. 
South Australia (Eastern Bays). 
Chondria dehilis Harvey. 
Frond 8 cm. to 14 cm. long, very small, widely dichotomous, flexuous, the 
ramuli alternate, spreading filiform, clavate at the apices, the ramelli

of the ramelli. Substance in young plants gelatinous, in older plants 
firmer.
