 Presl, Luzon, Cuming 165, in part. B. salicifolium Kaulf., collected "at

(3) B. egregium Copeland. Stipes clustered in form of a nest, 10 to 

 20 cm. high, stout, brown, black below and densely clothed with long black 

 scales; frond about I m. high, 30 cm. broad, pinnate, glabrous, moderately 

 dimorphous; pinnse acuminate, serrate, confluent at the top, lower down 

 attached to the rachis by a broad base but distinct, at the bottom reduced 

 gradually to remote auricles; fertile pinnae coriaceous, 15 cm. long, 15 to 20 

 mm. broad next the rachis, contracted graduallj' vmtil the sorus occupies 

 very nearly the whole breadth; pinnae of the sterile frond thinner but 

 broader; indusia coriaceous, persistent. 



Sibulan River, Davao, along mountain creeks, Copeland I3I4. 



(4) B. areolaris (Harrington, Journ. Linn. Soc. 16:28). Caudex long, 

 slender, twisted, naked; stipe 15 cm. long in the sterile, nearly twice as 

 long in the fertile fronds, glabrous; barren frond ovate, 10 to 15 cm. long, 

 10 cm. broad, pinnate; pinnae 7 to 9, lateral nearly sessile, terminal stalked, 

 linear-lanceolate, 5 to 8 cm. long, 12 to 16 mm. broad, acute, finely serrate, 

 obtuse or rounded at the base; texture coriaceous; nerves forming a series 

 of arches close to the midrib, thus forming on each side a row of long 

 narrow areolae parallel to the midrib; beyond this, nerves are free and 

 simple or forking; surface naked, except that the midribs and nerves are 

 a little chaffy below; fertile pinnae 7 to 9, narrowly linear, 4 to 5 cm. 

 long, rather distant; indusium narrow, marginal. 



Mount Majayjay, growing among the leaves of a Pandanus, Steere. 



(5) B. capense (L.) Schlecht (Lomaria procera Spr.). Caudex stout, 

 woody, elongate, clothed with large ovate or lanceolate-acuminate ferrugi- 

 nous scales; stipe 15 to 30 cm. high, stout, erect, scaly below; frond 30 

 to 100 cm. high, one-third as broad, the fertile and sterile not always very 

 different, coriaceous; pinnae of sterile frond linear, the lower stalked, with 

 rounded or cordate base, acuminate; fertile pinnae narrowly linear; indusium 

 broad, membranaceous, ciliate, sometimes slightly intramarginal ; rachis 

 densely chaffy. 



Luzon, Cuming 141. 



Southern Hemisphere and Mexico. 



(6) B. Fraseri (Cunn.) Mett. var. phiiippinense (Christ). Caudex 

 arborescent, 0.5 to 1.5 m. high, 1 to 2 cm. thick, black, clothed with lance- 

 olate-ovate, dark broAvn, subulate scales 3 mm. long, and above with the 

 bases of stipes, flexile, woody, bearing a crown of 6 to 8 fronds; stipe short, 

 3 to 4 cm. long, densely scaly; frond 40 cm. long, 20 to 25 cm. broad, long- 

 acuminate, attenuate to the base; pinnae about 12 to 18 on each side, 

 alternate, 1 to 2 cm. broad with their own breadth between them, strongly
