(33) BLECHNUM Linninus. 



Sterile fronds with free veins ^e\ceI)t in B. (irroUirc) , fertile with a 

 series of areola? along the eosta, otherwise free; soii along the far side 

 of these areohv, linear, usually continuous, parallel to the co.sta, sometimes 

 spreading over the parenchyma; indusium the shape of the sorus, opening 

 on the costal side. Mostly terrestrial ferns of moderate size, with erect 

 caudices. The two sections are usually treated as genera, but are not 

 sufficiently distinct.

 oblong-lanceolate, 30 cm. or more long, 10 to 15 cm. broad; pinnte numerous, 

 erecto-patent, subfalcate, linear, 10 cm. long, 1 cm. broad, narrowed 

 jrradually toward the point, dilated and connected at the base, the edge 

 inidulato-crcnate, the lower ones linear-acute and not much smaller than 

 the rest; texture coriaceous, both surfaces and rachis naked; veins fine;

(2) B. orientale L. Caudex erect, often subarborescent, clothed at the 

 crown with librillose, dark-brown scales; stipe 15 to 30 cm. high, strong, 

 erect, scaly at the base; frond 40 to 100 cm. high, ovate, with very numerous 

 close linear pinnae; pinnae 10 to 25 cm. long, 1 cm. broad, narrowed to a 

 long point, contracted to a sessile base, the upper ones decurrent, the lowest 

 abruptly reduced to mere auricles strung along the stipe; subcoriaceous, 

 glabrous; sori in a long continuous line close to the midrib.
