17*. Nephkodium (Lastrea) subcrenulatum", Bakery n. sp. 

 Stipe (incomplete) slender, castaneous, furnished, as is the rachia, 

 with a few minute, linear, brown scales, and a little pubescence. 

 Frond o,blong-]anceolate, membranous, glabrous, bright-green, 

 bipinnatifid, 8-12 in. long, 4-5 in. broad. Pinnse lanceolate, patent, 

 cut down nearly to the rachis into obscurely crenate, obtuse lobes 



\ 



2-2^ lines broad ; the central pinnae shortly petioled, |— | in. 



broad, the lowest pair deflexed and produced on the lower side ^ 



(I in. broad). Veins distinct, erecto-patent, 6-8-jugate, usually 



simple, but in the dilated segments of the posterior side of the 



lower pinnse forked. Sori median. Involucre small, glabrous, 



persistent. 



Most resembles N. cTirysolobum and the small forms of N, 

 cari^ense. 



N. pate2^s, var. madagascakiense. Baker. Dwarf (lamina a 

 foot long), densely pilose ; many lower pinnse gradually reduced ; 

 largest pinnse 2 in, long, 4-4^ lines broad ; segments at most a 

 line broad, completely filled up with sori, 8-9 on a side ; involucre 

 persistent, densely pilose. 



Eecedes from the type in the direction of the pubescent varie- 

 ties of IT, conterminum. 



45*. ]Sr. (Lastrea) anateinqphlebium, Baker^ n, sp. Stipe 

 (incomplete) grey, naked. Frond oblong-lanceolate, bipinnatifid, 

 moderately firm in texture, glabrous, l|-2 feet long, 7-8 in. 

 broad, narrowed at the base ; rachis finely grey-pilose, not scaly. 

 Pinnse sessile, lanceolate, acuminate, |-1 in. broad, cut down 

 nearly or quite to the racliis into crenulate ligulate segments \ in. 

 broad. Veins 8-9-jugate, simple, erecto-patent, very distinct. 



Sori small, supramedian, on the veins. Involucre minute, 

 fugacious. 



Allied to N, conterminum, 



53*. N. (Lastrea) loxgicuspe, Baker, n. sp. Stipe (incom- 

 plete) naked, pale brown. Frond oblong-deltoid, bipinnatifid, 1|- 

 2 feet long, 10-12 in. broad, the lower pinnse suddenly dwarfed, 

 the lowest represented by a gland only, moderately firm in tex- 

 ture, glabrous except on the midrib of the pinn^ beneath, which, 

 like the scaleless pale-brown rachis, is finely pubescent. Pinnse 

 very numerous, sessile, linear, with a long cusp, | in. broad, cut 

 down to a narrow wing into ligulate erecto-patent segments
