 Mag., Tokyo, VI. 1892, p. 46. 



Nom. Jap. Hikage-warabi (T. Makino). 



Hal. Prov. Tosa : Tokano (T. Makino ! 1884), Mt. Yokognra-yama 

 (T. 'Makino \ Aug. 28, 1887), Kochi (K. Nagaamma\ I88G : T. Makino ! 

 Aug. 1892), Beppu-mura (K. Watanabe ! herb. Sc. Coll. Imp. Univ. Tokyo, 

 Oct. 5, 1891); Prov. Yauashiro : Mt. Takao-yarna {T. Makino \ Nov. 7, 

 1893). 



This species comes near to Diplazium Doederleinii ( =Asplenium 

 DcsderltiiiiL Luers.), but is usually smaller, the frond more thinly herba- 

 ceous, the pinnules more deeply pinnatifid, and the ultimate segments 

 narrower and more clearly crenulatolobed. I have named it in honour of 

 my excellent friend Mr. Koichiro Naganuma. 



Athyrium viridifrons Makino nom. nov. 



Caudex creeping, rooting, with a number of thick bases of the old stipes. 

 Stipe elongate, stramineous, scaly towards the base, compressed and thick 

 at the base ; scales rufous-brown, broadly lanceolate, acuminate, thinly mem- 

 branaceous. Frond ample, deltoid, or ovate-deltoid, acuminate, tripinnatifid, 

 light green, thin, herbaceous, very thinly dispersed with very minute linear 

 scales; rachis slender, stramineous, nearly glabrate, naked but narrowly 

 winged at the superior portions ; pinnae nearly opposite, erect-patent, about 

 10-13 on each sides, nearly sessile, oblong-lanceolate, broadest at the middle, 

 acuminate, with narrow-winged rachis; pinnules spreading, lanceolate, 

 acuminate, sessile, slightly apart from one another, regularly deeply pinnatifid • 

 segments spreading, numerous, regularly arranged, a little apart from one 

 another, oblong, slightly dilated at the base, obtuse, crenulate or crenulato- 

 lobed, 5-12 mm long, 1^-4 J mm wide; veins rlexuous. pinnate; veinlest 

 free, erect-patent, simple or often 2-forked. Sori minute, oval or oblong, 

 nearer to the mid vein than to the margin, oblique, dorsal, often horseshoe- 

 shaped ; indusiura thinly membranaceous, ciliated.
