Syn. Filie. 370 ; N. Brownei, Desv. in Mem. Soc. Linn. Par. vi. 220 ; Gymno- 

 gramme Bruwmd, Kuhn. in Bot. Zeit. 1869, 458 ; Notholmna lasiopteris, F. v. M. 

 in Hook. Kew Journ. vi. 106 ; Ckeilanthes vellea, F. v. M. Fragm. v. 123. 



Hab.: Cape York, Daemei ; Cleveland and Eookingham Bays, W. Hill, Dallachy, Gulliver; 

 Gilbert Eiver, Daintree ; Suttor River, Bowman ; and other northern localities. 



Also in the West Mediterranean reRion The distinctions pointed out by Kuhn between the 

 Mediterranean and Australian plant do not hold good in all the Australian specimens. 



3. N. distans (distant), R. Br. Prod. 146; Benth. Fl. Austr. vii. 774. Very 

 closely allied to N. vellea, of the same stature and general habit and not always 

 easy to distinguish from it. The outline of the frond generally narrower, the 

 lobes of the pinnules smaller and the indumentum not so dense, assuming on the 

 under surface the form of bristles with little or none of the woolly hairs of 

 N. vellea. Sori the same.— Hook. Spec. Filie. v. 114. Ic. PI. t. 980, Syn. Filic. 

 872 ; Kunze in PI. Preiss. ii. 109 ; Bail. Litho. Ferns Ql. 171 ; Ckeilanthes 

 distans, A. Braun ; F. v. M. Fragm. v. 122. 



Hab.: Percy Island, A. Cunningham; Logan Biver, Fraser ; Brisbane Eiver, F. v. Mueller; 

 and many other localities both north and south. Found on rocks in dry situations. 

 Also in Norfolk Island, New Caledonia and New Zealand. 



4. N. fragilis (fragile). Hook. Spec. Filic. v. 114, t. 287, Syn. Filic. 372 ; 

 Benth. Fl. Austr. vii. 774. Rhizome horizontal, rather thick, scaly. Fronds 

 broadly deltoid in outline, in some specimens 1 to 1 Jin. long, on a slender stipes 

 twice as long, in others 3in. long and broad, with a firmer black stipes twice or 

 thrice as long, pinnate with numerous small deeply pinnatifid pinnules, the 

 ultimate lobes under 1 line long, each one bearing a sorus large in proportion. 

 Partial rhachis and under side of the lobes hispid with a few rigid hairs or bristles. 

 — Bail. Litho. Ferns Ql. 171 ; Cheilanthes fragillima, F. v. M. Fragm. v. 123. 



Hab.: Thursday Island. 



5. W. Prenticei (after Dr. Chas. Prentice), Baker New Ferns, 1892. 

 Rhizome short, creeping, covered with narrow dark-brown scales, or scale-like 

 hairs. Stipes 4 to 5in. long, slender, almost black, shining, with a few narrow 

 scales at the base. Fronds narrow, lanceolate, rigid, bipinnate. Pinnae crenate, 

 lower ones much longer than the upper ones. Sori containing small spore-cases, 

 the edges of the pinnae reflexed forming a narrow indusium. — Bail. Litho. Ferns 

 Ql. 171 ; Cheilanthes Prenticei, Luess. in Bot. Centralblatt, 1882, 442. 



Hab.: Thursday Island. 



6. If. glabra (smooth), Bracken. ; Hook. Spec. Filic. v. 115 ; from Bracken, 

 b'il. U. S. F^pl. Exp. 21. Rhizome tufted. Fronds 4 to 6in. long on slender 

 stipes, nearly or quite glabrous, lanceolate to ovate-lanceolate in outline, 

 bi-tripinnate, primary and secondary divisions ovate-oblong and obtuse, the 

 ultimate divisions or segments 2 or 3 lines long and 2 lines broad, oblong, 

 irregularly cut into obtuse lobes. Venation obscure. Sori without any trace 

 of indusium and following the sinuosities of the frond. 



Hab.: Near Brisbane, Dr. Prentice. 



82. GRAMMITIS, Swartz. 



(From gramma, a line ; the sori being linear.) 



(Gymnogramme, Desv.). 



Rhizome short or tufted or creeping. Fronds pinnate or bipinnate, with forked 



and free or reticulate veins. Sori linear or oblong, without any indusium, on 



veins diverging from the midrib, scattered or crowded in a broad intramarginal 



line.
