 (in Herb. Nos-fr.) (more lax, ultimate pinnules more cuneate and more distant, 

 sori very small).— The ordinary form of this delicate and elegant species, almost 

 entirely confined to the New World, which has ovate pinnatifid (not deeply) i>in- 

 nules, with sori not marginal, but on the disc, is distinct enough; hut, unfortu- 

 nately, there are copions specimens where the pini\ules are so dee])ly divided, and 

 into such narrow segments, that there is not room for more than one sorus, and 

 these have generally the fronds much contracted below, or rather that ])art 

 is formed of numerous dwarfed multifid pinnae, extending almost to the base 

 of the stipes in some cases : and there seem to be all intermediate grades. 

 None of the individuals here brought under J. cicutarium are radicant at the 

 apex, and (his may afford a character to maintain this species distinct from 

 A. rhizophi/llum, Kze., and its allies. I cannot but feel a little donbtfid about 

 my Maealisberg plant, which has tlie pinnules more dissected than in the com- 

 mon form of A. cicutarium, but the sori are very small, and always distant from 

 the margin. Mr. Moore has marked it as near A. myriophyllum : itself a very 

 dubious species. 



190. A. (Euasplenium) Giberfianum, Hook.; caudex short 

 thick descending densely fibrous clotlied witli suliulate scales 

 at the summit, stipites tufted numerous from the crown of 

 the caudex \h inch or a little more long green at length cas- 

 taneous chiefly at the back slightly scaly below winged above, 

 fronds 6 inches long membranaceous bright green lanceolate 

 pinnated, pinnae numerous approximate f of an inch long 

 ovato-lanceolate obliquely cuneate at the base and decur- 

 rent so as to form a wing to the rachis extending to the 

 insertion of the pinna next below, deeply pinnatifid, seg- 

 ments oblong lanceolate very acute entire, inferior ones sub- 

 cuneate bi-trifid, the lower sinuses deeper and extending 

 nearer to the costa^ veins simple or in the lower segments 

 once or twice forked, sori solitary near the base of each seg- 

 ment occupying as it were the disc of the piima neither ex- 

 tending to the rachis nor the margin scarcely a1)ove the sinus, 

 involucres membranaceous almost white, rachis green much 

 compressed winged on both sides with the dccurrent leases of 

 the pinnules at the apex frequently extended some length 

 beyond thepinucx and proliferous. — Hook. 2nd Cent, of Ferns,

 Index Fil. p. 137 [name only). 



Hab. Assumption, State of Paraguay, 650 miles altove Buenos Ayres, M. Gibert, 

 to whom I desire to dedicate the species (not from the " Island of Assumption," as 

 stated by Mr. Moore).^A beautiful species, yet I sometimes fear too nearly allied 

 to Aspl. cicutarium, a very variable plant. Its distinguishing characters may be 

 looked for in the pinnatifid rather pinnated pinna;, the very acute segments, the sori 

 all distant from the margin, the broad winged rachis, often prolonged and proli- 

 ferous at the apex.
