hastato-lanceolate acuminate pinnate, the lowest pair of pinna? 

 elongated 4-6 inches long and again pinnate, pinnce and pin- 

 nules all horizontal subsessile from a broad obliquely cuneated 

 base auricled above subexcised below lanceolate inciso-ser- 

 rate (scarcely subpinnatifid), serratures bristle-pointed, sori 

 biseriate or scattered, involucres at length almost concealed 

 by the capsule. — Kze. Bot. Zeit. vi. p. 509. Metten. Aspid.

Hab. Japan, Goring, C. P. Hodgson, Esq. Island of Tsus Sima, Gulf of Corea, 

 Wilford. — This again is a most distinct and well-marked Fern, and one of great 

 elegance, not likely to be confounded with any other. It is only the lowest pair of 

 pinnic that are mnch elongated and again pinnated ; in that respect therefore it is 

 more compound than several that follow in this " pinnated " section ; but not 

 enough so to be considered strictly bipinnate. 



20. A. (Polystichum) Tsus-Simense, Hook.; caudex short 

 thick olilique crowned with large black lanceolato-subulate 

 falcate black scales, stipites tufted slender a span long strami- 

 neous, at the base scaly with the same black scales as the caudex 

 mixed with slenderer subulate ones and black hairs, fronds 

 (the very young and undeveloped ones 2 and more inches high 

 clothed with long circinate black subulate and long pointed 

 scales) a span to a foot long finely acuminated chartaceous 

 bipinnate pinnate above, pinnas 1-1 j inch long shortly petio- 

 late from a broad base gradually acuminate falcate superior 

 base truncated and forming a large spinulose-pointed auricle, 

 pinnules very compact ovate spinulose at the apex entire or 

 with very minute mucronate serratures ultimate ones con- 

 fluent, superior pinnae simple lobato-pinnatifid, the lobes, spi- 

 nulose ultimate ones confluent into a long-attenuated apex, 

 lowest pair of pinnae scarcely smaller than the rest deflexed, 

 sori 2-4-6 on each side the costule, involucre thin-membra- 

 naceous orbicular and flat. (Tab. CCXX.) 



Hab. Island of Tsus Sima, in the Straits of Corea, C. Wilford. — I find no de- 

 scribed species to accord with this. Tlie scales of the caudex are singular in 

 shape and peculiarly black : the upper portion of the frond is pinnated, the rest re- 

 gularly bipinnate, tlie lowest pair of pinn;c deflexed. 



21. A. (Polystichum) semicordatnm, Sw. ; caudex thick 

 horizontal creeping (?) very densely clothed with long (| of an 

 inch) subulate scales, stipites solitary (not tufted) stout a span 

 and more long shaggy with long slender paleaceous scales at 

 length deciduous, fronds 2-.3 feet long broad or ovato-lanceo- 

 late (8-10 inches wide) coriaceo-membranaceous blackish-
