29. A. (Polystichum) moh'ioides, Bory ; caudex short 

 thick erect or oblique densely clothed with black-brown 

 glossy scales, stipites densely tufted stout subcarnose 3-6 

 inches or more long red-brown darker at the base with 

 largish patent brown scales, fronds oblong-lanceolate coria- 

 ceous subacute obtuse 6-12 and more inches long pinnate, 

 the pinnee short and ovate lobato-pinnatifid and crenated or 

 elongate and deeply pinnatifid with ovate segments or again 

 pinnate especially below, or bipinnate with the pinnules ovate 

 incised or serrated and even petiolate, serratures muticous, 

 sori close compact in two rows upon the pinnule or seg- 

 ments at length confluent, involucres close almost imbricated 

 orbicular dark broAvn slightly depressed in the centre, rachis 

 partially paleaceous. — Bory, Voy. Duper. Crypt, p. 267-

 Orange Harbour, Tierra del Fuego, Brackenridge. — A very distinct species, but 

 very variable, and the texture sometimes thick and coriaceous, sometimes simply 

 pinnate, or partially bipinnate or wholly bipinnate. It is quite peculiar to the 

 southern hemisphere, and chiefly confined to high southern latitudes, what may be 

 called South Patagonia embracing the Falkland Islands. Pceppig and M. Ger- 

 main indeed met with it in Chili proper ; but the one on the summit of a very 

 lofty mountain, Antuco, the other on the Andes of Chillon : and their specimens 

 are of a green colour and with much less of a coriaceous texture. Mettenius offers 

 the remark," fortasse speciei sequentis var." {Anpid. vesiitum, aculeatum, nobix), 

 from which I think the muticous serratures will always keep it distinct. Mr. 

 Brackenridge's specimens from Orange Harbour, its most southern locality, were 

 only 3-4 inches high, growing very dense and compact. 



30. A. (Polystichum) Cystostegia, Hook. ; stipites appa- 

 rently tufted 1-3 inches high tawny-brown and as well as 

 the broad rachis and undeveloped portions of the frond 

 paleaceous with copious long lanceolato-subulate pale ferru- 

 ginous scales quite slender upwards, fronds 4-6 or 8 inches 

 long oblong-lanceolate firm-membranaceous bipinnate, pinnae
