ASPLENIUM, § ATIIYRIUM. 223 



Ilab. Java, Blume fin Herb. Nostr.), Thos. Lobb, ZoUinger ? (Metten.J. 

 Khiisya, Griffith. Ceylon, Gardner, 1372. Upper Assam, Griffith. Khasya, 

 (rri///lh, Ilr/oker fit. e'f Thomson, clev. r)-6000 feet. Sikkiin, Hooker fit. et 

 Thomson. — My si)ccimeiis from the above localities of the continent of India are 

 named foliohsum, Wall., by Moore (different from my specimens from M'allich 

 under that name), and the Asptenium macrocarpon of Blume, in my licrharium, 

 (unquestionably Blame's Aspid. macrocarpon, of his Enumeratio I'il. Jav.), he 

 makes a synonym to it. If Mr. Moore be correct in the reference, the long pub- 

 lished character of Blume's macrocarpon will entitle his name to the preference. 

 The two in question are i)robal)Iy the same, but there are such variations in the 

 specimens that it is hard to define them, and equally so to define the limits of 

 this and the allied Indian species. Mettenius's figures of the piiuuc and pinnules 

 of his A. fallax well represent Blume's A. macrocarpon. 



225. A. (Athyrium) Nigritianum, Hook. ; whole plant 

 when dry quite black paler below, caudex short thick erect 

 fibroso-radicose, stipites aggregated stout 5-6 inches long 

 shaggy (as well as the stout rachis) with brown subulate vil- 

 lous scales, fronds 1-H foot long firm-coriaceous rigid lan- 

 ceolate acuminate attenuate below by the inferior dwarfed 

 remote pinnje bi-tripinnate, primary pinnse numerous 2 rare- 

 ly 3 inches long narrow-oblong acuminate nearly sessile, 

 pinnules 2-3 lines long (the largest of them) all petiolulate 

 obliquely rhomboid obscurely and obtusely auricled at the 

 superior base sublobate serrato-dentate, middle ones more 

 lobed inferior ones 3-lobate or ternately pinnate, ultimate 

 pinnules broad-cuneate subrhomboid, lowest pair reflected 

 upon the main rachis, veins obscure sunk subfla])ellately di- 

 chotomous, sori 1-3 rarely 4 on each pinnule or lobe rather 

 small oval-o1)long, involucre straight firm-coriaceous convex 

 entire almost black, primary rachis furrowed above, second- 

 ary ones slender, naked. — Hook. 2nd Cent, of Ferns, t. 44. 



Ilab. Prince's Island, Fernando Po, Barter, n. 1898. — A distinct and very 

 peculiar Asptenium, which has no very near relationship with any species known 

 to me ; remarkable for its firm rigid habit, very stout stipes, and main rachis, 

 shaggy with woolly hair-like scales, and the very black colour of the entire plant 

 when dry. I place it in the A/hyrinm-section with some hesitation, on account 

 of a certain peculiarity of habit, and of the convex involucres, which are very 

 firm and coriaceous, and nearly of the same colour as the (dried) frond. 



22G. A. (Athyrium) asp'uUoides, Schlecht.; caudex "ascend- 

 ing," stipites pale brown glossy 6-8-12 inches long ]ialea- 

 ceous at the base with large broad lanceolate-acuminate 

 fronds 1-2 (-4, Schlecht cnda/) feet long broad-ovate membra- 

 naceous tender dark green trii)innate, primary ])innse 6-8 

 inches long subflexuose very distant short-i)etiolate patent 

 ovato-lanceolate acuminate, secondary pinnules ^-2 inches
