Spei Afrieze australis (CKLoN, ZrvnER). — Frons plerumque 9-5 
cm. longa, cwspitosa, in aliis Algis aut in Zosteraceis repens 
gregaria, stipite nullo distincto, a basi fere ramosa, subpinna- 
tim dichotoma, Segmenta 2-4,5 millim. lata, linearia, superiora 
acuminata sspe secunda in exteriore latere segmenti terminalis 
ineurvati, nonnulla ex lateralibus quoque hamato-incurva ; ubi 
revera pars frondis aliis adproximatur, est ea regio costalis in- 
crassata, quz sustinenti alg: advertitur, et adfigitur ramulo pro- 
prio incurvato; dum libera suecreseit pars superior frondis magis 
linearis, novas lacinias generatura aut membranaceas acuminatas 
aut in cirrhos novos mutatas aut in formam rotundato-obcordatam 
abeuntes. Fructifera plerumque breviora, s:pe trifoliata, phyllis ob- 
tusioribus, singulis soro unico infra apicem instructis. Sori non- 
numquam pauci adsunt in media lacinia. — var.? maculatum (Sond.),
