Differs from B. stoloniferum by: fronds (both sterile and fertile) stiffly erect; blades subcoriaceous; sterile pinnae with costae grooved adaxially; fertile pinnae 30+ pairs, inequilateral and surcurrent at bases, arcuate, conduplicate, not apiculate at apices, of relatively uniform length from near blade bases to just short of blade apices. Terrestrial on seepage slopes along streams, conifer forests, pine-oak forests; 2300–2600 m. Mexico; Guat (Beaman 4203, UC); Peru, se Braz, Bol, Chile, Arg.; circumsubantarctic islands; se Australia, New Zealand.
