Frons flabellatim expansa, 4-7 unc. lata, basi cuneata, pluries dichotoma, laciniis linearibus cuneatisve, 4-4 
unc. latis et ultra, patentibus, apicibus obtusis emarginatis bifidisve. Substantia tenuis, membranacea, e cellulis super- 
ficiem versus minimis coloratis formata, interioribus magnis hyalinis.—Chartee non ۰ 
Our specimens of this plant are unfortunately barren, it resembles in outline the Phyllophora obtusa, but is of a 
very different consistence. Its nearest ally is the R. Palmetta, to gigantic specimens of which it may be compared. 
Prats LXXII. Fig. I.—1. a specimen of the natural size; 2, lacinia of a specimen with narrower fronds, also 
of the natural size. 
Dr. Montagne adds R. corallina, Grev., R. variegata (Halymenia, Bory), and R. bifida, Grev., as natives of Lord 
Auckland’s group, but the specimens are imperfect and they may belong to some of the former.
