Hab. New Mexico, Fendler, n. 1017, a.— Kuiize has well represented this 

 pretty plant, which has no inconsiderable affinity with N. deaJbata, but the zig- 

 zag rachis and singularly divaricated branches and branchlets with much of the 

 intricate habit of Cheilanthes dichotoma, readily distinguish it. The pinnules 

 are not much unlike in general shape those of our alpine Meadow-rue, Thalictrum 

 alpinum. 



13. l^.fragilis, Hook.; caudex?, stipites 2-4 inches long 

 slender filiform glabrous dark-purple as well as the rachises 

 both of which are fragile, fronds 1-2 inches long membrana- 

 ceous villous on both sides and at the margin with rather 

 long spreading white hairs deltoideo-bipinnate tripinnate be- 

 low, 'primary pinnse subopposite lowest pair petiolate un- 

 equally triangular, their secondary pinnae subsessile oblong- 

 ovate I of an inch or more long again pinnated, pinnules as 

 well as the superior secondary pinnae oblong 3-4 lines long 

 deeply pinnatifid with narrow linear inciso-dentate segments 

 which bear short naked interrupted sori of few capsules near 

 the slightly recurved margins. (Tab. CCLXXXVII. A.) 



Hab. Fitzmaurice river, N. Australia, rare, F. Mueller. — This is a very pecu- 

 liar species, small and delicate, fragile in the stipes and rachises, with much-di- 

 vided villose fronds and very sparse short sori scarcely corresponding with any 

 Poll/podium, and yet the sori are not sufficiently contiguous or confluent to war- 

 rant its being decidedly a Nofkochlmia, neither is there an involucre so developed 

 as to justify its being placed in Cheilanthes. Its affinity seems to be with N. 

 kirsuta, Desv. 



14. N. distans, Br. ; caudex scarcely creeping but rather 

 forming a short stout suberect ascending rhizome ferrugineo- 

 paleaceous, stipites tufted 1-3 inches long dark-brown sube- 

 beneous and as well as the rachises ferrugineo-paleaceous 

 with lanceolato-subulate erect scales, fronds 3-8-9 inches 

 long scarcely an inch broad subcoriaceous rigid long ferrugi- 

 nously hirsute above, beneath paleaceous with lanceolate 

 long hair-pointed scales especially on the costae and cos- 

 tules linear-oblong (nearly equal in width for the whole 

 length) obtuse bipinnate, primary pinnae petiolate ^-1 inch 

 long opposite or nearly so erecto-patent deltoideo-ovate those 

 of the lower half of the frond distant all pinnatifid at the 

 apex, pinnules few 2-3 pairs ovato-oblong obtuse lowest 

 ones pinnatifid at the base, the margins recurved and (before 

 maturity) subinvolucriform, sori continuous along the mar- 

 gin. — Br. Prodr. Fl. Nov. Holl. p. 146. Labill. iSert. Austr.
