upper surface glabrous and marked with concentric lines, mostly towards the 

 the upper part. The whole undcr-surface makes a thickly clothed buffy- 

 coloured tomentum, composed of short, slender, jointed hairs of unequal 

 length. Sori of both kinds scattered over the upper surface of a rather 

 older portion in irregularly roundish patches. Substance leathery and easily 

 torn up vertically. Colour reddish chestnut-brown, rather fading in drying. 



Remarhs : Peyssonnelia caulifera seems to resemble, in the external 

 appearence, to P. australis Sond., and under that name I sent some 

 specimens of this plant to the late Prof. Fr. Schmitz. But the present 

 plant has a single decumbent layer, while P. australis has many more 

 strata, as Prof. J. Agardh says in his Sp. Alg. Epicr. p. 388 " at stratum 

 decumbens magis evolutum seriebus cellularum pluribus superpositis, usque 

 6-7 vidi, saepe constituitur.'' Thus the present plant may stand in the 

 same section, ill which P. squamarla and others are placed, but differing 

 from related species, chiefly in having a stalk-like bundle of root-fibres.
