1 2 PATAGONIAN EXPEDITIONS I BOTANY. 



P. MOHRIOIDES (Bory) Presl. var. ELEGANS (Remy) C. Chr. 



Syn. Polystichum elegans Remy. 



Aspidium plicabtm Poeppig, var. laxum Kee. 



Polystichum mohrioides Christ. 



Aspidium mohrioides Hook. fil. 



South Patagonia; Skyring Water; W. Patagonia; Terr. Chubut, 

 Cholila. 



Add Macl., p. 133: 



P. MULTIFIDUM (Mett.) Moore. 



Stipes scattered, 15-30 cm., clothed with ovate dark scales; fronds 

 ovate, lanceolate, 50 cm. long, bipinnate, lower pinnae more than once- 

 pinnate, the lower pinnae deflexed; pinnules subdeltoid with ovate or 

 spatulate segments. Sori small, scattered. 



W. Patagonia, Rio Aysen ; also in Chili. 



P. MULTIFIDUM (Mitt.) Moore, var. AUTRANI Hicken, Anal. Soc. 

 Cient. Arg., 63 (1907) (reprint of 14). 



W. Patagonia, Canal Messier. 



P. MULTIFIDUM (Mett.) Moore, var. DUSENII, C. Chr. Some Ferns, p. 19. 



W. Patagonia, Rio Aysen ; S. Patagonia, Skyring Water. 



Whether P. orbiculatum (Desv.) Gay belongs to our district is rather 

 doubtful. The determination P. orbiculare Christ, given in Archiv. for 

 Botanik, Bd. 4, No. 12, p. 2, refers to P. multifidum var. Dusenii quoted 

 above. 



Polystichum vestitum (Forst) C. Chr. Macl., p. 133 (Dryopteris vcstita 

 (Forst.)) does not belong to the Fuegian-Patagonian flora, and should 

 be deleted. 



CYSTOPTERIS Bernh. (Macl., p. 133, Filix.) 



C. FRAGILIS Bernh. (Macl., p. 134.) 



The range of this species within our district is evidently wider than 

 Macloskie assigns to it. From Lago Argentine, Lago Viedma and Lago 

 San Martin it is known, and also occurs abundantly in the heart of S. 

 Patagonia near Yotel-Aik, by the Scheuen rivulet; commonly by Rio 

 Carren-leofu (also in Ushuaia and in South Georgia. G. M.)
