2. D. eaudata Rk. Br. Prodr. (1810) 151.—Rhizome short, suberect, 
emitting numerous black wiry rootlets. Stipes 2-4in. long, slender, 
black, smooth or nearly so. Fronds numerous, densely tufted, 3-12 in. 
long, rarely more, #-2in. broad, lanceolate, acuminate or caudate, usually 
membranous, pale-green, pinnate almost to the top, more or less dimorphic ; 
sterile usually shorter than the fertile and less erect, often decumbent, 
sometimes almost flaccid; pinnae oblong or linear-oblong, obtuse, sharply 
serrate. Fertile fronds longer, usually harsher and more rigid, erect ; pinnae 
3-13 in. long, }-4 in. broad, narrow-linear, often attenuate, the lower ones 
usually conspicuously auricled at the base, the uppermost decurrent and 
confluent, terminal pinna usually very long, caudate. Sori in a single series 
on each side of the midrib.—A. Rich. Fl. Nouv. Zel. (1832) 76; A. Cunn.

Norte Istanp: From Kaitaia southwards to Cook Strait, but local and often 
absent from large areas. Sea-level to 2500 ft. 
Apparently a common Australian plant, ranging from Cape York to Tasmania. 
Some of the New Zealand forms approach very close to the preceding species; but 
usually it can be distinguished by the smaller size, by the sterile fronds being of a 
different shape and more flaccid than the fertile, and by the narrow fertile pinnae with 
conspicuously auricled bases. A small variety found on the Rimutaka Range, Wel- 
lington, is said to have scented fronds, and to have been formally collected by the 
Maoris for the purpose of mixing with oil to anoint the person; but I have never been * 
able to preceive any fragrance. Perhaps Polynodium pustulatum has been mistaken for 
it. I have seen no authentic specimens of Colenso’s D. sguarrosa, and have followed 
Mr. Baker (Ann. Bot. v (1891) 221) in referring it to D. caudata. 
21. GYMNOGRAMME Desv. 
Rhizome short and tufted or long and creeping. Fronds very various, 
small or large, pinnate or 2—3-pinnate, rarely simple. Veins simple or forked, 
or more or less copiously anastomosing. Sori placed on the veins on the 
under-surface of the fronds, oblong or linear, often elongated, simple or 
forked. Indusium not developed. Sporangia stalked, bursting trans- 
versely, surrounded by an incomplete vertical ring.
