primary veins straight and distant nearly to the edge ; areoles 

 fine, with # copious free included veinlets ; sori large, in two regular 

 rows ; indusium reniform. Hook. Syn. Fil. 297. A. grande. J. Sm.

Perak, sea level. {Day ; King, No. 2,347.) Perhaps only 

 a form of repandum, with reniform instead of polystichioid 

 involucres. 



(Also in the Malay Islands, Philippines, and Solomon 

 Islands.) 



12. Aspidium multicaudatum. (Wall. Cat., 377.) Perak, 

 at the Taepang Waterfall, at no elevation. (King's collectors.) 

 Wallich's specimens were collected at Chappedong, Birma. The 

 sori are, I believe, always apical on the free veinlets, the magnified 

 section showing the venation in page 337, F. B. I. not being correct. 



12A. Aspidium dubium. (n. sft.) Stipes up to 3 feet long, 

 f inch thick at base, furnished copiously towards the base with 

 narrow-lanceolate scales ; fronds up to \\ feet long by the same 

 breadth across the base ; bipinnate below, pinnate upwards, and 

 pinnatifid towards the apex ; the pinnae and pinnules cut deeply 

 down into lanceolate acuminate lobes ; texture papyraceo- 

 herbaceous ; hairy on the veins, especially on the under surface ; 

 main veins distinct to the edge, with copious areoles and many 

 free included forked veinlets even in the acuminated lobes ; sori 

 large, generally in a single row on each side of main veins, on con- 

 nected veinlets, or terminating free veinlets. Nephrodium cicuta- 

 rium var. ? dubia. Clarke and Baker ; Linn. Soc.Jour. xxiv./. 417. 



Makum Forest, Lukhimpur, Assam. [Mann, Clarke) This 

 has the outline, texture, and colour of multicaudatum, but the 

 venation of cicutarium ; in this the venation is more copious, with 

 numerous forked free veinlets, the veins anastomosing copiously 

 even in the lobes ; the large sori often compital; in multicaudatum 

 the venation is not so copious, free veins few and not forked, and 

 the venation in the lobes nearly quite free ; the sori smaller and 

 much more scattered, and always terminating free veinlets.
