Hab. in oceano Australi ad Novam Zelandiam insulasque vicinas 

 (D'Urville, Hooker). — Callus radicalis exiguus. Frondes aggre- 

 gatse 12-25 cm. et ultra longaa, 8-15 cm. ambitu latte, flabelliformes.

 subattenuatus, 1-3 mm. latus, distiche ramosissimus. Pinme 5- 

 6 millim. longre, alternse pinnatoe vel bipinnatae, pinnulis brevibus, 

 alternis, patentibus, serratis v. pectinatis, apice subacutis. Sectio 

 transversa monstrat cellulam ampliorem axialem, utrinque cellula 

 minus ampla denique cellula angustiori praebente ita ut in sectione 

 ipsa celluhe magnaj 5 secus unicam seriem dispositaj conspiciantur. 

 Cystocarpia sessilia involucro quadrifoliato pectinato cincta, sptue-
