the lower ones largest excepting the lowest one smaller ; second rachis 

 slender, very shallowly canaliculate in front, prominent dorsaliy, glabrous, 

 pale stramineous. Segments cut down to the rachis, numerous, alternate, 

 regularly and pectinately arranged, a little remote, erect-patent, adnate and 

 decurrent at the interior base to the rachis, linear-lanceolate ; gradually 

 attenuated above, acute-acuminate, recurved but revolute when dried on the 

 margin, entire but often obscurely crenulate, attaining 23 mm. long, 3 mm. 

 broad ; midrib slender, prominent beneath ; veins erect-patent, rather loose, 

 usually bifurcate near the base but some of them again bifurcate, the 

 superior ones simple. Suri of 3-4 sessile and globose sporangia, dorsal at 

 the lower part of the exterior branch of veins, rather loosely arranged on 

 about lower half of segments, one-serial on each side. Bud axillary, 

 globose or subovoid, densely clothed with scales which are similar to those 

 of the base of stipes.
