Hah. in mari Australi ad Cap. Bon?e Spei et Portum Natalense 

 (Hb. Martens), ad Novam Hollandiam (Hb. Diesing) et Tasmaniam 

 (Mlis. Paris.), ad Novam Zeelandiam (Hb. Harvey). — Frons exi- 

 mie stuposa, 9-20 cm. et etiam ultra longa, per totam longitudi- 

 nem ramis crebre vestita. Rami decomposito-pinnati. Pinnae pin- 

 nulaeque subdistiche exeuntes, sed ita plerumque flexae, ut undique 

 jugamentum tegere videantur, omnes eximie fastigiatae. Pinnulne in 

 jugamento leniter flexuoso versus apicem sensim densiorcs et bre- 

 viores; inferiores valde elongatas et simpliciusculas, unde omnes 

 oequalem altitudinem in apice pinnarum assequuntur. Articuli dia- 

 metro breviores. Fructus inter pinnulas (sphacelatas) in axilla 3-4 

 aggregati, pedicello tenui requilongo suffulti, sphoerici, diametro pin- 

 nam superante, intra perisporium hyalinum grumosam substantiam 

 foventes. Species fere maxima generis, fere Styp. scoparium aemu- 

 lans, at spinulis subulatis distichis hujus carens.
