Hab. Prov. Echizen : Mt. Toehiki-toge (Herb. ! Sc. Coll. Imp. Univ. 

 Tokyo,, July 2, 1881) ; Prov. Tosa : Asakura-mura (T. Makino ! Sept, 23, 

 1892); Prov. Yamashiro : Umegahata near Mt, Takao-yama {T. Makino \ 

 Nov. 7, 1893); Prov. Omi : Maebara (T. Makino ! herb. Sc Coll. Imp. 

 Univ. Tokyo, Nov. 1894) ; Prov. Bikuchu : Mt. Knrikoma-yama {T. Makino ! 

 Aug. 1890, very luxuriant form). 



An extraordinary variety. The ultimate segments are larger and more 

 laxly disposed. 



There are some specimens in the herbarium of the Science College, 

 Imperial University of Tokyo, which were collected in the altitude of 4000 

 feet on Mt, Fuzi, and these may be referred to my variety rather than 

 to Athyrium macrocarpum (Blume), although I have some doubt on this 

 point. 



Diplaziutn Textori (Miq.) Makino. 



Rhizome widely creeping, hard, black, loosely rooting, scattered with 

 the basal remains of old stipes, clothed with scales at the apical part ; 

 roots hard, stout-filiform. Stipe long, slender, hard, dark-green, black at 

 the base, stout-wiry, sulcate on the front side as is the rachis, densely 

 clothed with scales at the base, but often sparsely scattered above, 25-48 

 cm long. Scales 4-7 mm long, linear, gradually acuminate towards the 

 apex, fuscous- black, loosely spinuloso-denticnlate, rigidly membranaceous, 

 with nerves stronger towards centre and longitudinally narrow areoke, those 

 of the superior portion of the stipe dark-brown. Frond deltoid-lanceolate, 

 acuminate, 25-40 cm long, 12-24 cm broad, simply pinnate, but pin- 

 natifid at the apical portion, glabrous above, very thinly villose underneath, 

 chartaceous, not herbaceous ; pinna? about 12-15 on each side, patent, 

 lower ones sometimes slightly deflexed, subtruncate at the base, with short 

 petioles which are about 5-13 mm long in the lowest one, but superior 

 ones sessile, and uppermost ones decurrenti-adnate to the rachis, lanceolate, 

 somewhat falcate, acuminate, largest ones about 15 cm long, 5 cm wide, 

 lower ones halfway cut down to the midvein or more deeply pinnatifid, middle 

 ones about one- third cut down and superior ones crenato-lobate : segments 

 subfalcato-ovate to oblong-ovate, obtuse, obsoletely denticulate towards the 

 apex, but subentire in the superior ones, those of the lowest pinme often 

 acute falcato-lanceolate and 3 cm in length ; rachis slender, hard, very laxly 

 scaly or nearly glabra te ; veins obliquely patent, pinnate ; veinlets about 

 2-6 on each side, but about 11 in the largest segments, erect-patent, loose,
