ANEMIA. 



The fummit of each frond is obtufe, and fimply pinnatifid. 

 Spikes triply and minutely compound, with linear (hort feg- 

 ments ; ihevcjlalhs hifpid. 



12. h.. tomentofa. Downy Anemia. Swartz n. lo. 

 Willd. n. 1 1. (Ofmunda tomentofa ; Lamarck Did. v. 4. 

 652.)— Frond doubly pinnate, oblong, clothed with tawny 

 down ; leaflets crefcent-fhaped, entire ; the lower ones 



bluntly pinnatifid. Common ftalk. downy Found by 



Commerfon at Buenos Ayres. A pretty fpecies, feven or 

 eight inches high, exhahng the fmell of myrrh, and covered 

 all over with fine, long, cottony, tawny down. The common 

 Jlalk is rather flout, twice the length of the leafy part, which 

 is about two inches broad. Spikes compound, on (lender

 n. II. Willd. n. 12. (Ofmunda fulva ; Cavan. Ic. v. 6.

 vvhat downy ; leaflets elliptic -oblong, bluntly pinnatifid, or 

 ferrated. Spikelets partly whorled. All the ftalks hairy. 



Gathered by Louis Nee, on the hill called Pan de A%ucar, 



or the Sugar-loaf, thirty-two miles from Monte Video. 

 Above a loot high, with very hziry Jlalh, and a broad 

 frond, doubly pinnate throughout, except at the very top. 

 Leaflets three-quarters of an inch long, and one-third as 

 broad, uniform, fomewhat decurrent. The JpHes feemto be 

 fimply compound, their tranches horizontal, linear, deeply 

 notched, many of them in whorls of three or four together ; 

 their common flalks and ribs hairy, fending off one or three 

 lateral branches, which we have feen in no other fpecies.

/S. Willd. (A. afplenifolia ; Swartz n. 10. Ofmunda 



afplenifolia ; Savigny in Lamarck Dift. v. 4. 652.) 



Frond doubly or triply pinnate, triangular ; leaflets obo- 

 vate, fharply toothed at the end, partly notched, hairy, as 

 well as their common rib. Common flalk nearly fmooth. 

 Spikelets digitate. — Native of the Weft Indies, particularly 

 of Hifpaniola, in dry rocky or ftony places. Its large 

 handfome, fhining, ftriated frond bears confiderable refem- 

 blance to our common yfjplenium yldiantum-nigrum, to which, 

 and not to the real genus Adianlum, the fpecific name alludes. 

 The wvtktA flalk is often a foot high ; the length of the leafy 

 part almoft as much. The copious leaflets meafure about 

 half an inch, and are flrongly ftriated ; convex above ; 

 paler, and rather moft hairy, beneath ; all their ftalks hairy. 

 Spikes fomewhat panicled ; their ultimate divifions radiating, 

 or finger-like, linear, flat. Capfules of a light fhining 

 brown. 



Sir Jofeph Banks has favoured us with feveral fpecimens 

 of a variety of this fern, gathered at Campechy by Houftoun, 

 which differs chiefly in being not above a fpan high, with a 

 lefs compound frond, and having fometimes, from the fame 

 root, much narrower, almoft linear, leaflets. The common 

 Jialls are alfo rather more hairy, and the fpiies more com- 

 pact. It is neverthelefs an evident variety, and probably the 

 ^ of WiUdenow, to the charafters of which it anfwers.

mcnts denfely crowded. — Gathered by Plumier in a dry 

 ftony traft of land in Hifpaniola. We find no good autho- 

 rity for its ha.ving ever been found elfewhere, nor by any 

 other botanift. Linnaeus adopted this fpecies entirely from 

 Plumier, between whofe figure and defcription there is a 

 ftrange contrariety. The plate, drawn and engraved by 

 himfelf, evidently exhibits the hvixren frcnds as doubly pin- 

 nate, each of the numerous primary divifions being com- 

 pofed of a rather fmaller number, (about thirty,) of oval or 

 ovate, fomewhat decurrent leaflets, except a few of the 

 uppermoft, which run into a terminal ferrated point. His 

 defcription fays, " the tufted root bears feven or eight ribs, 

 about a foot and a half long, garniihcd nearly throughout 

 their whole length, with longifh, narrow, pointed, yellowifh- 

 green leaves, but ilightly furrowed, and all cut into rather 

 broad, and fomewhat pointed notches." As the author is 

 known to have loft many of his fpecimens, we can only fup- 

 pofe this defcription was made from too (light a view of his 

 own drawing, without a re -examination of the plant, which 

 he feems to have gathered but once. A few taller and more 

 flender _y?«//j', fpvinging alfo from the root, and doubly pin- 

 nate in the firft inftance, bear innumerable capfules crowded 

 into denfe maffes, which we prefume to be compofed of 

 narrow compound fegments, like the other fpecies. At 

 leaft the analogy of A. fliculifoUa hereafter defcribed jufti- 

 fies this fuppofition. 



16. A. aurita. Auricled Radical Anemia. Swartz 

 n. 15. Willd. n. ly. (Ofmunda aurita; Swartz Ind. 

 Occ. 1578.) — "Frond pinnate; upper leaflets fimple, 

 ovate, obtufe, finely toothed, unequally wcdge-fhaped at the 

 bafe ; lower ternate. Spikes compound, on radical ftalks ; 

 fpikelets digitate." — Found by Dr. Swartz, on the fides of 

 lirae-ftone rocks, in the interior part of Jamaica. Roots 

 creeping, (lender. Common flalks feveral, crowded, about a 

 fpan high, flender, moft hairy and fcply at the bafe ; downy 

 and roughifh upwards. Each bears an ereft frond, fix 

 inches in length ; doubly pinnate in its lower part, the 

 leaflets fmall, roundifh, the terminal ones larger and rhom- 

 boidal : the upper part is fimply pinnate ; leaflets oblong, 

 oblique at the back, dilated on the upper edge, at the bafe, 

 into an obtufe angle : all the leaflets are coriaceous, fmooth 

 and (hining, (lightly convex, ftreaked with radiating veins ; 

 finely crenate at the margin ; more opaque beneath. 

 Cluflers, (or rather ^;7fj-,) compound, on radical ^ij/Zj-, clofe 

 to, and refembling, thofe of the \iwre-a fronds ; their branches 

 compound, nearly oppofite, fpreading ; their ultimate feg- 

 ments digitate, lanceolate, acute, bearing on the upper fide 

 roundifh-ovate bivalve capfules, with concentric ilreaks on 

 their apex, and interfperfed with minute fcales or hairs.

 doubt.

 PI. 1520. Plum. Fil. 137. t. 160. Petiv. Fil. n. 171.

 elliptic-oblong, acute, ferrated ; terminal ones larxeolate, 



pointed. Spikes in whorled branches, on radical ftalks 



Gathered once only, in the forefts of Hifpaniola, by 

 Plumier, nor does it appear that any other botanift has even 

 feen this fpecies, his work having been Linnxus's fole 

 authority. The genus, therefore, can only be prefumed 

 from analogy, but we think this analogy as fair as in any 

 fimilar inftance. The tufted root fends up many barren 



fronds, which are fupported by long rough flails, and three- 

 cleft in the firft inftance, then doubly pinnate ; their common 

 outline pentagonal, a foot in diameter ; their leaflets ufually 



near
