sate I v to be stated that the two genera. Pe?iy a and Jfacrocii?ridivm, must 

 be united into one as I have formerly done. 



Polypodium (Pleopeltis) Uchiyamae Makino sp. nov. 



Khizome repent, rather long, tortuous, terete, branched, densely covered 

 with nigro-castaneous scales, radicant with fibrous short-branched nigro- 

 castaneous roots ; scales small, linear-subulate to lanceolato-subulate, much 

 attenuated above and long-acuminate, rounded and peltate at the base, 

 loosely patent-dentate, membranaceous, with fine and distinct oblong areolae, 

 21-3 mm. long. Frond loosely placed on the rhizome, with a long stipe, 

 lanceolato-linear to linear, acuminate or subacuminate with an obtuse 

 point, very gradually attenuated below and at length angustately marginate 

 on both sides of the stipe above, entire or somewhat repand, narrowly in- 

 volute on margin when dry, chartaceo-coriaceous, entirely green glabrous and 

 impunctate above, paler and very thinly dispersed with very minute adpres- 

 sed papilloso-pulverulent hairs under lens beneath, 2-10 cm. long, 4-10 mm. 

 broad ; midrib very narrowly prominent above, obtusely prominent beneath ; 

 venation immersed, no distinct main veins ; areolae usually hexagonally 

 oblong to elliptical, with a simply or duplicately furcate free venule within ; 

 stipe slender, wiry, terete, shorter than the frond, about 1-5 cm. long, the. 

 upper portion gradually passed into the frond. Sori in the upper or whole 

 portions excepting the lower part, forming a row nearer the midrib than 

 the margin or sometimes midway between them, shortly apart in each 

 other but the superior ones close and often confluent when mature, rounded 

 to elliptical, prominent, more or less immersed, somewhat prominent on 

 the upper surface of frond, intermixed with scales ; scales linear to oblong- 

 linear, acuminate, long-filiform-stipitate, few-denticulate, and usually several- 

 areolate, exceeding the sporangia, attaining about 2J mm. long. Sporangia 

 n umerous, 1 ong-pedicellate.

This species is very closely allied to Polypodium lineare Thunb., es- 

 pecially to the var. distans Makino, but differ* from the latter by the size 

 of frond, more slender stipe, presence of papillose hairs beneath,, spotless 

 ;tbovr. and form of scales in sorus. . It also approaches • to Pdypodiwn
