11. G. (Mert.) unihraeulifera, Mooi-e ; st. and rachis deciduously tomentose and 

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

 fiabelliform, scarcely glaucous beneath; pinnce 4-6 in.L, 1 in. br., lanceolate, 

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

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



Hab. S. Africa. — Perhaps too near Q. Chmninghami of N. Zealand.

 often proliferous ; branches dichotomously fiabelliform, subcoriaceous, yellow- 

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

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

 scarcely recurved ; sori of 2-4 caps. — Hi:. 8p. I. p. 6. /. 8. B. 



Hab. Chili, as fer south as Valdivia ; Juan Fernandez, Bertero. 



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

 yellow or yellow-brown when dry ; branches dichotomously fiabelliform ; pinnce 

 broad-lanceolate, suberect and compact, 4-6 in. 1., 1 in. br., pectinato-pinnatifid ; 

 segm. narrow-linear, strongly veined, the m'argins singularly revolute, concealing 

 the sori ; caps. 1-4 in a sorus. — Hk. Sp. 1. p. 7. i 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-pinnatiiid, 4-6 in. 1., 1-1^ 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. l.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.) revoltita, H. B. K.; st. and racAzs paleaceous, especially beneath ; 

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

 foliaceous) ; pinnce linear-acuminate, 6-7 in. 1., J-J in. br., deeply pinnatifid, 

 much and laxly divaricated and falcate ; lci>es ovate, horizontal, obtuse with the 

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

 Brackenridge i Summit of the Blue Mountains, Jamaica, Purdie. — My authentic speci- 

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

 pinnae than true recoluta. 



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

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

 sericeo-paleaceous (rarely, in that state, with circinate lieads), 6-14 in. 1., ^1 in. 

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