Small. Leaves long-petiolate, ova to-rotund^ or rhombeo-ovate, or 

 elliptical, irregularly sharp-clentate, abruptly cuneate at the base, glabrous, 

 efarinose but often with a mere trace of farinose beneath, 7-13 mm. long, 

 7-11 mm. wide; petiole narrowly winged, attaining about 2 J cm. in length. 

 Scape erect, exceeding the leaves, 4^-5^ cm. high, 2-3-flowered ; involucre 

 subulate, acuminate, shorter than the pedicels. Calyx tubuloso-campanu- 

 late, 5~fid, persistent ; lobes very slightly shorter than the tube, erect, 

 lato-lanceolate, acutish. Capsule cylindrical, twice the length of the 

 calyx, 6-7 mm. long ; valves obtuse. 



Nom. Jap. Hime-kozahura (T. Makino.) 



Hah. Prov. KuvUchu : Mt. Hayachine (0. Sato ! July 28, 1902). 



This is only rarely found on alpine mountains of the northern part of 

 Japan. I approve of Dr. K. Miyabe's view to take Primula macrocarpa 

 Maxim, as a synonymv to P. mistassinica Michx. 



Athyrium nikkoense Makino, sp. nov. 



Caudex short, erect or ascending, very thickly covered with the basal 

 remains of old stipes, densely rooting below. Stipes c^espitose, much 

 shorter than the frond, narrow, pale when dried but brownish dark at the 

 base, densely clothed with scales towards the base, about 1-14 cm. long; 

 scales lanceolate to li)iear, acuminate, entire, membranaceous, ferrugineo- 

 rufous, often castaneous towards the centre, attaining about 10 mm. long, 

 venules very delicate forming many longitudinal areolae. Frond simply 

 pinnate, narrowly lanceolate, acuminate, narrowed below, 8-40 cm. long, 

 2i-9 cm. broad, often rather firmly herbaceous, glabrous ; rachis slender, 

 weak, pale when dried but sometimes purpurascent, often fibrillose-squamose 

 at the base of pinnae ; pinnae numerous, 15-28 on each side, usually alter- 

 nate, sessile, patent and often approximate, but the inferior ones apart 

 and more or less reflexed and gradually diminished in size, narrowly 

 deltoid-lanceolate and usually acuminate, but narrowly deltoid and acute or 

 obtuse in the inferior ones, truncate or subtruncate at the base, pinnatiiid 

 with closed sinuses, attaining about 41 cm. long in the middle ones; lobes 

 elliptical or ovato-oval, rounded or obtuse at the apex, irregularly pauci-
