Generally confined to the forest and preferring the shadiest parts, seldom 

 seen in more open situations. Fertile fronds develop during the summer and 

 ripen Feb. — April. 



Masatierra: C. Chifladores, slope above the innermost part of Pto Fran- 

 ces, c. 500 m; ridge between Q. Laura and Q. Piedra agujeriada, 650 m; 

 Pangal (Johow); N. slope of La Damajuana, c. 450 m; the crest separating 

 the Q. Damajuana from V. Anson, on rocks, 150 m; along the road to Porte- 

 zuelo, in the woods (nos. 153, 589); Q. Gutierrez (no. 49); C. Salsipuedes, Q. 

 Helechos, 660 m, rather common and also epiphytic; Pto Ingles (Johow); Q. 

 Juanango, very large plants (no. 611); Q. Villagra, here and there near the 

 path; Q. de la Choza, dense forest, 250—300 m, very numerous. 



Masafuera: O. de las Chozas, dry bed of a stream; Q. del Mono, dark 

 ravine, 570 m; Q. de las Casas, humid sheltered corners (no. 510); Q. del 

 Varadero, dark fissures below the waterfall; Q. Angosta, at the waterfall; Q. 

 Loberia, forest patch, 280 m. In the alpine region: C. del Barril (no. 531); 

 edge of western precipice at the foot of Las Torres, 1370 m (no. 422). 



A fairly constant species, varying mainly in size. The rhizome is com- 

 monly described as creeping. This is not quite correct. It is erect from the 

 first, but soon produces underground runners, from which new plants arise; 

 with age these give rise to new runners with fasciculate leaves. The scales of 

 the rhizome are entire. 



B. valdiviense is certainly related to B. lanceolatum (R. Br.) from Australia 

 and New Zealand but well characterized. Small plants resemble B. penna 

 marina, and young plants of B. Schottii may be confounded with B. valdivi- 

 ense, but will be recognized by the dentate scales of the rhizome, which is long 

 and slender, by the scattered leaves and the prominent hydathodes on their 

 upper surface just within the margin. 



We have little doubt that L. lanceolata Colla and L. I' Herminieri Hemsl. 

 (not Bory) quoted above must be referred to B. valdiviense. Hemsley quoted 

 specimens collected by Bertero and by MOSELEY: the former is beyond doubt 

 the L. lanceolata, which according to Colla's few remarks seems to be ordi- 

 nary B. valdiviense, and the latter is perhaps a large form of the same. Johow 

 reprinted Hemslev's remarks with the addition that he had collected it in 

 Masatierra and that it might be united with L. attenuata (= B. Schottii). This 

 is no wonder for Joiiow's specimens (!) are B. Schottii. The genuine B. 

 1 Herminieri Bory, a West Indian species, does not occur in Juan Fernandez. 



Area of distribution: South Chile, Valdivia and Chiloe; Juan Fernandez.
