Not uncommon in the forests, often climbing on trees and arboreous ferns. 

 The fertile fronds are developed in late summer and ripen in March — April. 



Masatierra: From Pto Frances to Juanango, ranging from about 200 m 

 to 6 or 700 m (nos. 286, 564, 1180); also on the south side, in the quebradas 

 of Villagra. 



Masafuera: O. de las Chozas, in forest 475 m (no. 517); Q. dc las Casas, 

 not rare in the canyon. 



In 1910 the reasons were given why this should be considered a distinct 

 species, and the differences between it and the closely allied B. attenuation 

 ( Willd.) and B. tneridense (Kl.) C. Chr. were explained. We can add that the 

 basal scales are more distinctly toothed and frequently concolorous in B. Schottii, 

 subentire and black in the centre in B. meridense. 



No. 1 180 is an anomalous form with the sterile pinnae deeply pinnatifid 

 in the external half, with subfalcate, acute segments. 



Area of distribution: Fndemic.

Fairly common in the woods, preferring open glades and stony ground 

 near running water; also in the drier tracts. Fertile fronds develop during the 

 summer and ripen Feb.— March. 



Masatierra: Pto Frances, scattered in the forest, c. 500 m; C. Centinela, 

 in the woods; Pangal, west branch on dry open ground; main gorge, at the 

 waterfall; O. Damajuana, small waterfall, c. 250 m; V. Colonial, in all the que- 

 bradas, common along the road to Portezuelo (no. 565, no. 331 f. anomala); 

 C. Salsipuedes, up to 670 m; Q. Juanango, along the brook, c. 200 m; Villagra 

 common in the large quebrada; S. slope of Co Chumacera, in the Boehmeria- 

 grove; B. Chupones, 2—300 m. 



Masafuera: Q. de las Chozas, dry bed of a stream, 570 m (no. 437); 

 Q. de las Casas, common along the course of the stream; Q. Angosta, at the 

 waterfall; Q. del Varadero, waterfall; the Correspondencia Camp, in the ravine 

 1 160 m; heath near Las Torres, 1350 m (dwarf specim.). 



B. chilense belongs to a group of closely allied species which by some 

 authors are united under the name B. capense (Thunb.) Schlecht. This group 

 has never been critically revised. For the present it cannot be decided which 

 of the numerous species described should be regarded as valid. Here we prefer 

 to deal with B. chilense as a separate species, although we are not prepared 

 to give good distinctive characters. 



According to JoHOW L. Reedii is a form with fronds partly fertile, partly 

 sterile. Such anomalous forms are occasionally met with in other members of 

 the group. No. 331 of the present collection is such a form, with all the pinnae
