10. G. (Mert.) Cunninghami^ Hew.; st. and costce beneath hairy and deci- 

 duously scaly ; fr. often proliferous, coriaceous ; branches dichotomously flabel- 

 liform, glaucous beneath, and hairy ; pinnce linear-lanceolate, acuminate, often 

 falcate, 4-6 in. 1., \-l in. br. ; segm. linear, acute ; caps. 2-4 in a sorus. Uk. Sp. 1. 

 p. 6. t. 6. B. Hk. fil. N. Zeal. 2. *. 71. 



Hab. N. Zealand. 



- 11. G. (Mert.) iimbraculifera, Moore ; st. nn&rachts deciduously tomentose and 



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

 flabelliform, scarcely glaucous beneath ; pinnae 4-G in. 1., 1 in. br., lanceolate, 

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

 caps. Mertensia, Kze. in Linn. 18. p. 114. 



Hab. S. Africa. Perhaps too near 0. Cunninyhami of N. Zealand. 



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

 often proliferous ; branches dichotomously flabelliform, subcoriaceous, yellow- 

 green when dry ; pinnce linear-lanceolate, spreading or recurved, 4-6 in. 1., ^-f in. 

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

 scarcely recurved ; sori of 2-4 caps. Hk. Sp. 1. p. 6. /. 8. B. 



Hab. Chili, as far south as Valdivia ; Juan Fernandez, ertero. 



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

 yellow or yellow-brown when dry ; brandies dichotomously flabelliform ; pinnae 

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

 seam, narrow-linear, strongly veined, the margins singularly revolute, concealing 

 the sori ; caps. 1-4 in a sorus. Hk. Sp. 1. p. 7. t 6. 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 ; pinnce lanceolote, acumi- 

 nate, falcately curved, pectinato-pinnatifid, 4-6 in. ]., l-l in. br. ; lobes narrow- 

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

 sorus. Mertensia, Poir. G. acutifolia, Hk. Sp. I. p. 7. t. 8. A. 



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

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

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

 seems to be uniform in its respective characters. 



15. G. (Mert.) revolwta, H. B. K.; st. and rachis paleaceous, especially beneath ; 

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

 fuliaceous) ; pinnce linear-acuminate, 5-7 in. 1., -|-f- 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. .7- A. M.pru- 

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



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

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

 men of M. subflabellata, Brack., is more glabrous, and has slenderer and 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., -1 in. 

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

 cous beneath ; caps. 2-4, mixed with rufous hairs. Hk. Ic. PI. 1. 1. 92. Sp. p. 1. 



Hab. Andes of Quito and Peru. 



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

 branches of the fr. repeatedly dichotomous, subcoriaceous, leafy; pinnae 5 in. to
