This is the so-called L. lanceolata of Japan, of which I have in hand 

 specimens from Nippon and Quelpaert. It differs from real L. lanceolata 

 in the paleae, in being more coriaceous, and most conspicuously in the 

 sori. From L. malayana, it differs most notably in not being winged to the 

 base; and the fronds are more scattered and more coriaceous. In texture 

 it approaches L. involuta. 



LOXOGRAMME MALAYANA Copel. nom. nov.

 2: 84, Tab. 36, non Grammitis lanceolata Sw. 



Blume's description and plate in "Flora Javae" are complete and make 

 a new diagnosis superfluous. L. lanceolata (Sw.) Presl is a plant described 

 from Bourbon and found in East equatorial Africa. It is represented, 

 for instance, by No. 9 of Rosenstock's Filices Africae Orient. Germ., 

 collected by Daubenberger on Kilimanjaro. Its sori are costal and much 

 less spreading, and the frond is stipitate and has its broadest part 

 farther from the apex. L. malayana is decidedly taller, broadest near the 

 tip, then less acuminate, and winged nearly or quite down to the insertion 

 on the rhizome. The sori are spreading, and imbricate wh^n in full fruit, 

 and may reach nearly to the margin. Mettenius (Polypodium No. 216) 

 has described the Javan plant as Polypodium Loxogramme, but that name 

 must probably be held as fixed by his citations of synonymy and therefore 

 as itself applying to the real L. lanceolata.
