ASPLENIUM SAMPSONI Hance 
POLYPODIACEZ 
ASPLENIUM SAMPSONI Hance, Ann. Sci. Nat. V. 5: 257 (1866); C. Chr. Ind. Fil. 
130 (1905). 
Asplenium Belangeri Dunn & Tutch. (non Kze. 1848) Fl. Kwangt. & Hongk. 344 (1912). 
Rhizome thick, short, erect, densely scaly; scales blackish, lanceolate, dense 
at apex; fronds caespitose, stipe fleshy, 3-6 cm long, sparcely clothed in blackish, 
irregularly armed scales, lamina lanceolate, 13-25 cm long, 2-4 cm broad, 
acuminate, gradually narrowed towards base; pinne 17-28-jugate, patent, subses- 
sile, the lower ones gradually reduced into a broadly deltoid outline below 1 cm 
long, the middle ones 1.5-2.5 cm long, 1 cm broad, oblong, obtuse, base unequal, 
being auricled at anterior side, deeply pinnatifid; segments 5-8-jugate, linear, pecti- 
nate, uni-nerved, the anterior basal one generally 2-3-forked; tewture herbaceous, 
green; sovz linear, one to each segment, industwm membranaceous, entire, open 
upward.

This distinct endemic species is*closely related to A. Belangert (Bory) Kze. of 
tropical Asia, to which it was reduced by Baker (Cf. Syn. Fil. 223), from which it 
differs, however, in much smaller size with narrowly lanceolate frond, gradually 
narrowed towards the short fleshy scaly stipe, which is, as rachis, sparcely 
clothed in black, irregularly armed and distinctly reticulated scales. From A. 
prolongatum Hk., our fern differs in non-prolongated, and rooting apex of frond of 
a lanceolate outline, on much shorter stipe, and in very patent or subhorizontally 
spread, more copiously and regularly pinnatifid pinne, of which the lower ones are 
gradually shortened.
