4. Kuhn and Carruthers have lately again separated as a species the Aus- 

 tralian plant, which is -ZV. JBrownii, Desv. It has longer stipes and fewer pinnae 

 han the European plant, the lowest little or scarcely reduced. 



4*. N. obducta, Baker ; st. I in., brown, naked ; fr. lanceolate, bipinnate, 8-9 

 in. 1., l|-2 in. br. ; rachis densely tomentose ; pinnae numerous, subsessile, ligu- 

 late, I in. br., lower distant, gradually reduced ; pinnl. oblong, obtuse, upper 

 adnate, lower sessile ; texture membranaceo-carnose ; upper surface dull-green, 

 glabrescent, lower densely paleaceous; sori punctiform, hidden in tomentum.

11*. N. Newlerryi, Eaton; st. tufted, 3-5 in. 1., nearly black, \vhenyoung 

 whitish-tomentose, at length nearly smooth ; fr. as long as st., lanceolate-oblong, 

 3-4-pinnate ; ult. segm. obovate, crowded, |-^ lin. br., entire or subcrenate ; both 

 sides covered with a dense white tomentum of slender entangled hairs, more dense 

 below ; sori rather large, at last emergent from the tomentum. 



Hab. California, Dr. Newberry, Prof. Wood & Brewer. 



12*. N. paucijuga, Baker ; st. tufted, f-1 in., castaneous, filiform, naked like 

 rachis \ fr. lanceolate, f-1 in., simply pinnate ; pinnae 3-4-jugate, upper close, 

 oblong or lanceolate, entire, lowest deltoid, distant, sessile, slightly lobed, 2 lin. br. ; 

 texture membranous ; surfaces green, glabrous ; veins distinct, fine, erecto-patent, 

 sori brown, marginal. 



Hab. Port Darwin, North Australia ; communicated by Sir E. Schomburgk. 



13*. N. cinnamomea, Baker ; st. tufted, 1-5 in., castaneous, densely clothed at 

 first, like the rachis, with soft pale-brown hairs ; fr. oblong-lanceolate, 2-3- 

 pinnate, 3-4 in. 1., l|-2 in. br. ; pinnce close, lanceolate, sessile, |-| in. br., lowest 

 distant, not at all or little reduced ; pinnl. oblong, obtuse, most simple adnate, 

 lowest sometimes free and pinnate ; texture not at all rigid ; under surface clothed 

 with lax pale-brown hairs ; sori brown, continuous.

3. Var. G. procurrens, Fe"e ; veins more distinct and more raised than in the 

 type ; rachis and under surface less pilose.

23*. G. Gardneri, Baker ; st. tufted, castaneous, \-\ ft., pubescent ; basal 

 scales linear, pale-brown ; fr. deltoid, tripinnatifid, 3-4 in. each way ; lower 

 pinnce much largest, long-stalked, unequal-deltoid, 2-2^ in. br. ; lowest pinnl. 

 short-stalked, deltoid, deeply pinnatifid, with short blunt lobes ; texture mem- 

 branous ; both surfaces green, pubescent ; sori as in tomentosa and rufa.

27*. G. Sellowiana, Mett. ; st. 2-3 in., castaneous, densely pubescent upwards 

 like rachis ; fr. lanceolate, bipinnate, 3-6 in. 1., -f in. br., narrowed from the 

 middle to both ends ; pinnce numerous, close, lanceolate, % in. br., free at base, cut 

 down to rachis into few obovate-cuneate pinnl. with reflexed margins ; texture 

 subcoriaceous ; upper surface dull-green, thinly, lower densely, pilose on the 

 ribs ; sori brownish ; veins subpinnate in the pinnules. Kuhn, Linn. 36. p. 69.
