11. G. (Mert.) umhraculifcra, IMoore ; st. and racJns deciilnously tonientose and 

 subpalcaceous ; fr. often proliferous, flaccido-coriaceous ; branches dichotomously 

 fiabelliform, scarcely glaucous beneath; j)itw<x 4-G in. 1., 1 in. br., lanceolate, 

 subcaudato-acuminate, pectinato-pinnatifid ; lobes narrow-linear ; sori of 3-5 

 cap>s. — Alertensia, Kze. in Linn. 18. p>- H'i- 



Hab. S. Africa. — Perhaps too near G. Cunninr/hami of N. Zealand. 



12. G. (Mert.) pedalis, Klfs. ; st, and 7-achis with deciduous, chaffy scales ; fr. 

 often proliferous ; branches dichotomously flabelliform, subcoriaceous, yellow- 

 green when dry ; pinnce linear-lanceolate, spreading or recurved, 4-0 in. L, \-j in. 

 br., deeply pinnatifid, oblong-ovate, subglaucous beneath, horizontal, the margins 

 scarcely recurved ; sori of 2-4 c«/)5. — Hk. Sp. \. p. 6./. 8. B. 



Hab. Chili, as far south as Valdivia ; Juaa Fernandez, Bertero. 



13. G. (Mert.) cryptocarpa, Hk. ; glabrous; fr. proliferous, coriaceous, deep 

 yellow or yellow-brown when dry ; branches dichotomously flabelliform; pinna 

 broad-lanceolate, suberect and compact, 4-5 in. 1., 1 in. br,, pectinato-pinnatifid ; 

 segm. narrow-linear, strongly veined, the margins singularly revolute, concealing 

 the sori ; caps. 1-4 in a sorus. — Ilk. Sp. 1. p.'t.t G. A. 



Hab. S. Chili and Chiloe ; Falkland Islands. 



14. G. (Mert.) quadripartita, Hk. ; fr. coriaceous, black when dry, rufous- 

 brown beneath, and there deciduously chaffy on the costse, not proliferous, only 

 once forked ; each branch flabelliformly dichotomous ; jnnncB lanceolote, acumi- 

 nate, falcately curved, pectinato-pinnatifid, 4-G in. 1., l-l|in. br. ; lobes narrow- 

 linear, subfalcate, sharply acute, the margins a little recurved; caps. 1-3 in a 

 sorus.— Merteusia, Pair. G. acutifolia, Hk. Sp. \. p. 7. t. 8. A. 



Hab. Straits of Magellan, Port Famine.— Very dark-coloured, quite black above when 

 dry, red-brown beneath, reuiarkable in not being proliferous. This and the three pre- 

 ceding species Lave a strong family resemblance, and a very compact habit ; yet each 

 seems to be uniform in its respective characters. 



15. G. (Mert.) revoluta, H. B. K.; st. and rac7«5 paleaceous, especially beneath ; 

 fr. repeatedly dichotomous, rarely proliferous, rigid, subcoriaceous (geinmce often 

 foliaceous) ; pinna; linear-acuminate, 5-7 in. 1., \-^ in. br., deeply pinnatifid, 

 much and laxly divaricated and falcate ; lobes ovate, horizontal, obtuse with the 

 margin recurved, subglaucous beneath ; caps. 2-4. — Hk. Sp. l.p.7. t.l.A.. M.pru- 

 inata. Mart. {Kze.). M. subflabellata, Brack. {Moore). 



Hab. Andes of Quito, alt. 9-10,000 ft., Hiunhohlt. Brazil {Klotzsch in Herb, nostr.). 

 Braclccnridyc ? Summit of the Blue Mountains, Jamaica, Purdie. — My authentic speci- 

 men of M. suhJfubelkUa, Brack., is more glabrous, and has slenderer ami less divaricating 

 pinnae than true revoluta. 



16. G. (Mert.) simplex, Hk. ; st. subpaleaceous, undivided ; fr. simple, linear- 

 lanceolate, pectinato-pinnatifid, acuminate at the apex, or, if undeveloped there, 

 sericeo-paleaceous (rarely, in that state, with circinate heads), 6-14 in. 1., h-l in. 

 br. ; lowest seg in. free, all obliquely patent, from a broad base linear-oblong, glau- 

 cous beneath ; caps. 2-4, mixed with rufous hairs. — Hk. Ic. PL 1. t. 92. Sp. p. 7. 



Hab. Andes of Quito and Peru. 



17. G. (Mert.) pubescens, II.B.K.; st. and racMses often paleaceous or woolly; 

 branches of the fr. repeatedly dichotomous, subcoriaceous, leafy; pin7i(8 5 in. to
