Horn. Jap. O-hirobanolnuwarabi (T. Makino nom. nov.), 

 Hab. Prov. Tosa : Kitagawa in Nanokawa (T. Malxino ! 1885), Omoto 

 in Ogawa-mura (T. Makino ! . 1885, Aug. 17, 1887). 



A more robust one than the typica, from which I can not specifically 

 distinguish. The pinnules are narrower. The inferior sorus is more 

 frequently double at the top instead of being hamate, which is also the 

 condition frequent in the typica. This is due probably to the confluence 

 of the veinlet with the upper part of the hamate indusium. In general 

 habit this resembles A. macrocarpum (Bl.) and A. nigripes (Bl.) Moore, 

 but in the shape of the sori it is widely different irom the former, and 

 in the shape of pinnules from the latter. 



Athyrium Filix-fcemina Roth. 



Var. nigropaleaceum Makino var. nov. 



Stipes erect, slender, shorter than the frond, thinly scaly throughout 

 but denser towards the base, fuscous at the base ; scales fuscous- black, 

 shining, lanceolate, curled when dry. Frond oblong-lanceolate, acuminate, 

 40-60 cm long, 10-18 or more broad, herbaceous; pinnae erect-patent or 

 spreading, narrowly lanceolate, much decreasing in size in the inferior ones, 

 he lowest one sometimes about 2J cm in length, middle ones largest and 

 10-15 cm long, 1J-3 or sometimes more wide; pinnules patent, sessile, 

 adnate to the secondary rachis in the superior ones, lanceolate, about J-1J 

 cm long, 2-6 mm or more wide, inciso-lobed ; lobes ovate or elliptical, 

 usually acutely or obtusely paucidentate, obtusely truncate at the top ; 

 veinlets simple. Sori 1-4 to a lobe, situated on the infra-medium of 

 lower veinlets, about 1 mm long, .slightly curved, or hamate at the top ; 

 indusium rimbriato-ciliated. 



Nom. Jap. Miyama-meshida (Z. Matsumura). 



Hab. Prov. Kaga : Mt. Haku san (Herb. ! Sc. Coll. Imp. Univ. Tokyo, 

 sub nom. Asplenium melanolepis, Aug. 8, 1881); Prov. Shinano : Mt. Ondake 

 (Herb. ! loc. cit sub nom. Asplenium melanolepis, July 28, 1881) ; Prov. 

 Ugo: Mt. Chokai-zan (Herb.! loc. cit. sub nom. Asplenium welanolepis 

 July 28, 1887); Prov. Echigo : Mt, Shimidzu-toge (T. Makino \ Sept. 1888) 



In the size and form of the froud this variety accords with the European 

 type, but the scales of the stipe are intensely fuscous-black. It is found 

 in the middle and northern parts of the main-land of Japan. The 

 frond is usually smaller and narrower than in var. melanolepis (Fr. et Sav.), 

 but frequently broader ones may occur, which serve as the connecting link 

 of the two varieties.
