from the second by having the much shorter fronds and the 

 mainly bifurcate veins, from the third by not having a distinct 

 stipe, and from the fourth by having the frond with the short- 

 acuminate apex, entire margin, and entire-margined indusium. 

 I have named this species in memory of Mr. Yoemon Nakano 

 of the Kagoshima Normal School. 



Woodsia tsurugisanensis Making, sp. nov. {Euwood- 

 sia.) 



A little fern, about 7-13 cm. high ; caudex short, erect or 

 ascending, forming a thick mass with the densely tufted old 

 erect stipes (which are |-2cm. in length) above and rooting 

 below ; roots delicate, filiform, hard, with short rootlets, black 

 or badious-black. Stipes erect, tufted, gracile, shorter than 

 the frond, 1^-4^ cm. long, articulated below the middle, rather 

 densely scaly towards the base, naked above, stramineous but 

 fulvous towards the base ; scales erect-patent or patulous, 

 broadly ovate to ovato-lanceolate, acuminate or acute with a 

 filiform tip at the apex, usually cordato-rounded at the base, 

 entire or very minutely subdenticulate, thinly membranaceous, 

 subhyaline, fulvous, enerved, very finely areolate, about 2-5 mm. 

 long. Fronds erect, narrowly lanceolate or lanceolate, acu- 

 minate towards the apex, bipinnatisected or bipinnatiparted, 

 membranaceous, quite glabrous, 3-lOcm. long, 8-22 mm. wide; 

 rachis slender or capillaceous, straight, viridescent, canalicula- 

 ted in front. Pinna; several to subnumerous on each side, 

 laxly arranged, sessile or very shortly stalked, subopposite or 

 alternate, patent in the lower ones but erect-patent in the 

 upper, narrowly ovato-deltoid to deltoid, obtuse or acutish at 

 the apex, obliquely broadly cuneate at the base, largest in the 

 middle ones, pinnatisected into 3-10-pinnules, attaining about 

 13ram. long; pinnules erect-patent or spreading, alternate, sessile, 

 loose, ovate or broadly ovate, obtuse, cuneate below, 3-4- 

 lobate ; ultimate-lobes oval or ovato-oval, rounded-obtuse at 

 the apex, attaining about 4 mm. long; veins slightly impressed 

 above as well as the venules, flexuous, laxly pinnately venuled;
