This pigmy fern is rarely found in Japan. The fronds of my speci-

Polypodium lineare Thunb. var. distans Makino. 



Rhizome long-repent, slender, wiry, 1-1 J mm. across, emitting fibrous 

 roots below throughout, distantly placed with small protuberances which are 

 basal remainders of old stipes above, simple or laxly ramose, scattered with very 

 minute deltoid or deltoid ovate acuminate subpeltate brownish-black deciduous 

 scales ; scales which are clothed on the basal knot of stipes very minute, 

 deltoid-ovate, acuminate, closely reticulated with blackish-brown venules, 

 irregularly eroso-dentate on the margin. Fronds persistent, simple, in a 

 small number, distant, linear-lanceolate, distinctly stipitate, gradually attenuat-

 and at length decurrent to the stipe, entire or slightly repand, narrowly involute 

 along the margins, 8-20 cm. long, 4-13 mm. or rarely 17 mm. wide, mem-
