Diminutive caudex, smaller fronds, shorter, thinner and more blunt 

 pinna', and asperous. purplUi-castaneons stipes and rachis of the present 

 species clearly distinguish it from the much stouter one, Blechnum nippo- 

 nicum m. The next species also differs from the present one mainly by 

 having an elongated rhizome smaller fronds, and broader and more blunt 

 pinnte of fertile fronds. 



Blechnum amabile sp. now 



Rhizome slender, creeping, stout-liliforni. 'o aring the remains of old 

 stipes throughout, emitting fibrous roots with < lark-rufous hairs, clothed with 

 lanceolate to ovate, acuminate, ferruginous, membranaceous scales towards 

 the extremity. Sterile fronds tufted at the apical end of the rhizome, 

 oblong-lanceolate, 12-30 cm long. 2-fUem wide, regularly pectinate-pinnate, 



reiiexed, a littla apart from one another or sometimes closely approximate 

 and even imbricated, oblong-linear, often hardly falcate, entire, very 

 narrowly involute along margins, acutely obtuse, entirely adna'te with slightly 

 dilated or seldom very scarcely contracted base to the rachis, inferior ones 

 gradually diminished in size and^ more distantly and distinctly separated, 



inconspicuous; veinlets erect-patent, forked but pinnate at the inner lowest 

 one in each pinna: rachis slender, glabrous, sleii.lerlv channelled above; stipes 



long. light green tinged with rose-colour, extremely fme-asper, >us furnished 

 with scales at the basal portion. Fertile fronds equal to sterile ones in 

 hight but often taller, pinnate, similar to the sterile in the outline but 

 somewhat narrower, with also longer stipes; pinna? patent, very slightly 

 curved upwards, a little distant, oblong-linear, entire, obtuse, decurrent and 

 adnate with the suddenly dilated base to the slender rachis the inferior
