82 ASPLENirM, § EUASPLENIUM. 



Pacific, Utria Bay (Seematnt), Society Islands {Bidwill in Herb. Nostr.), and to 

 the Galapagos {Capt. Wood) ; and is, in the New World, the representative of A. 

 Nidus in the Old. — More particular localities are piven in our * Kilices Exoticjc ' 

 above quoted. It is best distinguished, both from A. Nidii,s and A. Auxtralasicum , 

 by the absence of the marginal vein ; but in the shari)ly carinated costa it most 

 resenihh's the latter species. All the fronds of the numerous specimens I have 

 seen of this jdaut are attenuated gradually at the base into a short stipes: never 

 broad and obtiibc there, nor quite sessile. A singular variety is in my Her- 

 barium, with the fronds deeply and irregularly incised at the margin ; gathered in 

 French Guiana by Le Prieur. 



9. A. (Euaspleiiium) sinuutum, Beativ. ; caudex scarcely 

 any, fronds fasciculated 1 ^ foot long coriaceous lato-lanceolate 

 scarcely acuminate entire subsinuate attenuated gradually at 

 the base into a short l)lack shining semiterete stipes grooved in 

 front, costa below at the back nearly plane, in front singularly 

 ))roinincnt and sHghtly channelled, veins rather distant free 

 and clubbed at the a])ices, sori linear narrow occupying much 

 of the frond between the costa and margin. — Beauv. Fl.

Hah. Western Tropical Africa ; Oware, Pafisot de Beai/vois. River Nun, 

 Vogel. Fernando Po, on Oil-Palms, Barter, in Baikie's Niger Exped. — This 

 very much resembles those states of A. serralum of the tropics of America, wilh 

 entire margins to the frond, anil I should probably have referred it to that species, 

 had not the possession of it in a living state enabled us to distinguish characters 

 scarcely visible in the dried specimens, viz. that the back of the costa is re- 

 markably depressed, while the front is unusually promineut, as shown in our 

 figure in ' Filices Exoticae.' 



10. A. (Euasplenium) CVrron, Hook. ; fronds glabrous li 

 foot long about 1^ inch broad submembranaceous loriformi- 

 lanceolate acuminate scarcely attenuated and very obtuse at 

 the base, stipes scarcely any, veins rather distant as well as 

 the linear sori which are suberecto-patent, occupying a good 

 portion of the frond and neither extending to the costa nor 

 to the margin. 



Hab. W. African coast, south tropics, near Elephant's Biiy, Dr. Curror. — I 

 have seen no caudex of this species, but my otherwise perfect specimens i)0ssess 

 the very short stipes, about 2 lines long. The base of the frond is scarcely at 

 all contracted or dccurrent, hut obtuse below. The breadth of the fiond is there- 

 fore pretty uniform for the greater part of its length, giving it a loriform character. 

 The veins and the sori are more distant than is usual in this grouj), and their 

 direction much less patent. Its affinity is perhaps with A. sinuatum, from which 

 the above characters and the want of the long stipes will readily distinguish it. 

 The frond is also much more membranaceous. 



11. A. (Euasplenium) squamuJatum, Bl. ; caudex short 

 thick, fronds tufted coriaceo-meml^ranaceous 1 i foot Ions: 2-3
