rather loose, conspicuous beneath. Sori 4-13 to a pinnule, in two regular 

 rows near the costa, sometimes also 1-3 to an auricle, oblique, narrowly 

 oblong, 1J-3 mm long, very slightly curved, lower one often hamate at 

 the top; indusium membranaceous, subfimbriato-erose.

Kelated to Asplenium Wardii Hook., but more rigid in the texture; 

 the pinnules more numerous and more sharply pointed at the apex ; the 

 scales much fuscous-black. 



Athyrium Wardii (Hook.) Makino. 



This species was included among Euaspl enium , a section of Asplenium, 

 first by Sir. W. J. Hooker and then by J. G. Baker ; but it must, in 

 my opinion, be referred to Athyrium, for it frequently possesses sori 

 characteristic of Athyrium. Its general habit is also like that of the other 

 members of this genus. 



Var. major Makino var. no v. 



Stipe long, about 35-40 cm. long, clothed with linear and dull-brown 

 scales. Frond ample, deltoid-ovate, 30-50 cm long, 20-30 cm broad, 

 bipinnate but pinnatifid at the apical portion, herbaceous, naked ; pinnae 

 about 10 on each side, obliquely patent, moderately distant from one 

 another, lanceolate, acuminate, petioled, largest one 24 cm long, 6 cm 

 broad ; pinnules nearly horizontally patent, shortly petiolulate, a little 

 remote from one another, subdimidiato-oblong-lanceolate, obtuse with acute 

 teeth at the apex, obliquely cuneate at the base, shallowly pinnatifid into 

 crenato- lobes few- toothed, but obscure in superior ones, with a rounded- 

 ovate auricle at the upper lower side, largest one 3 J cm long, 12 mm 

 broad ; rachis slender, subflexuous above ; veinlets erect-patent, rather loose, 

 2-forked, but lower ones pinnate and upper ones simple, those in the 

 auricle simply pinnate or spuriously 4-5-times forked. Sori in two regu- 

 lar parallel rows near the costa, oblique, linear-oblong, 2-4 mm long, 

 very slightly curved, lower one doable at the top ; indusium membranaceous, 

 acute or subobtuse at both ends, obscurely denticulate or nearly entire 

 on the margin.
