 Nom. Jap. Kiji-no-wo. 



Diagn •• Fronds coespitose, rising from a circular disc, 

 copiously branched almost from the base in distichous manner, 

 membranaceous, ancipito-compressed above, subcylindrical in older 

 parts, faintly midribbed, narrowly winged and pectinato-pinnatifid 

 with broadly subulate or deltoid, patent lacinlse, whose lengths 

 are shorter below, subequal to or a little longer above than the 

 breadth of rachis. Fruits of both kinds axillary and stipitate. 

 Tetrasporic receptacles elongato-ovoid, shortly pedicellate. Cysto- 

 carps flattish-globular or reniform with a furrow-like opening on 

 the summit.

Fronds arise solitary or a few together from a broad scutate 

 and circular disc which is 5-8 mm. broad, and branch copiously 

 almost from the base. The mode of ramification is distichous 

 and the plant attains 15-20 cm or more in height. Branches 

 are irregularly decompound in alternate manner, intermixed with 

 longer and shorter ones, erecto-patent, and furnished with acute 

 axils. 1 he lower portion of frond as well as of larger branches 

 is, in older specimens, subcylindrical by the decaying off of 

 lateral teeth ； but other part of frond is pectinato-pinnatifid with
