LEPTOGRAMMA CAUDATA Ching in Sinensia 7: 98 t. 4. 1936. 
Dryopteris africana Hayata, Ic. Pl. Form. 4: 187 t. 124, A-B. 1914 (non C. Chr. Ind. Fil. 1905). 
Rhizome oblique, or short-creeping; fronds fasciculate at the growing apex of the rhizome, stipe gracile, 
stramineous, moderately hirsute throughout, 5-10 cm long, lamina elongate, deltoid-lanceolate, gradually 
long-acuminate, 10-16 cm long, 35 cm broad above the hastate base, simply pinnate below the broad and 
deeply pinnatifid upper half; free pinnae 3-5 pairs, sessile, the upper ones become more and more adnate 
as they go upwards, the basal pair of pinnae generally much the longest, 4-2 cm long, 1 cm broad, broadly 
lanceolate, acute, horizontally patent or somewhat deflexed, apex acute or obtusish, base unequal, ie. the 
lower side cut oblique, the upper side as broad as the upper part, pinnatifid less than half way down into 
6-4 oblique, deltoid, obtuse entire lobes; pinnae above the basal pair half as long, patent or oblique-patent, 
more or less adnate, of similar shape as the basal ones, less deeply lobato-incised, close, base roundish or 
subtruncate, equal, apex obtuse or acute; texture herbaceous, moderately hirsute on both sides, margin 
ciliate; vers in lobes usually 3-jugate, simple, free from flexuose costule, the basal pair of the contiguous 
groups reach the leaf margin a little way above the sinus; sori linear along the lower veins of each group, 
hirsute due to the presence near the top of the sporangia of some upright pale-colored needle-like unicel- 
lular hairs. 
Fukien: Foochow, Lukiang, F. P. Metcalf 5002C (type), August 10,1926. Taiwan: Mt. Arisan, Hayata 
et Sasaki, January 1912; Faurie 529, June, 1914. 
A peculiarly distinct species, different from all other known species of the genus in the narrowly elon- 
gate fronds with much produced basal pair of pinnae.
