2. Cyrtomium caducum. There are apparently two varieties 

 of this species — one with the pinnae coriaceous, the veins 

 nearly always free, the pinnae often becoming much lobed, pin- 

 natifid or even perfectly pinnate — the other much thinner 

 in texture, the veins rather copiously anastomosing, even half way 

 between the midrib and margin, the pinnae never becoming pinna- 

 tifid. The former is abundant on the Khasia Hills, the latter 

 near Darjeeling and at Munipore. 



i. Aspidium singaporianum. Perak sea level. {Day.) The 

 rhizome is erect in all Mr. Day's specimens. 



ia. Aspidium Kunstleri. (11. sp.) Stipe, rachis, and partial 

 rachis minutely pubescent ; frond i-ij feet long, deltoid-ovate, 

 pinnate, upper pinnae narrow-lanceolate, about 5 inches long by 

 f-i inch broad, entire or with scalloped margins, lowest pair 

 broad-deltoid, the lower margin towards the base being produced 

 into 3-4 long lobes, the largest being 4-5 inches long, upper 

 margin deeply scalloped, texture rather coriaceous, surfaces 

 glabrous, except the main veins, primary veins zigzag, tolerably 

 prominent nearly to the margin, cross veins forming areoles, free 

 veins rare not forked ; sori very small, numerous, and scattered 

 between the main veins generally on connected veinlets. 



Goping, Perak. King 1 s collector , No. 405. Outline of pachy- 

 phyllum, but pinnae much narrower, venation and sori different.

 stipes 8-18 inches long, naked or nearly so, winged upwards ; 

 fronds 10-12 inches long, 7-8 inches broad, deeply trilobate; 

 lobes lanceolate, long-acuminate, the lateral ones 5-6 inches long, 

 \\-2 inches broad, the intermediate one about 10 inches long, 

 2^-3 inches broad ; margins entire ; texture papyraceo-her-
