original A. tomentosa and deltmdea are the less-developed forms of the less-divided 

 variety, with which agree the Neilgherry A. Wightiana, Gardn. (Beddome, t. 66), and 

 Abyssinian A. Schimpenana, Presl. The former has an unusually strong stem, both 

 that and the rachises densely ferrugineo-tomentose ; whilst a plant gathered by Dr. Wel- 

 witsch in Angola is like /3, but nearly naked, with the divisions blunter than in the 

 extreme form. Besides the synonyms already quoted, we appear to include the following, 

 which are given as distinct by Sturm ; viz. ruhroslipes, Pohl, fer)-uginea, H. B. K., Rod- 

 diana, Link, ohlonga and imbricata. It has been gathered lately in Natal. 



15. A. trichorhiza' Gardn. ; cated. with a dense tuft of bright red-brown fibril- 

 lose scales f in. ]. at the crown ; 5^. 1-2 in. ]., densely clothed with white woolly 

 tomentum ; barren segm. ovate-deltoid, 2-3 in. 1., 1-1 1 in. br., bipinnate ; pinnae 

 close, spreading, lanceolate, with several close roundish or oblong pinnl.; texture 

 coriaceous ; both sides when young completely enveloped in dense woolly tomen- 

 tum ; panicle subsessile from the base of the barren segm. — Hk. Ic. t. 876. 



Hab. South Brazil, Gardner 4080, Burchdl 7043, 1881. — A very distinct species. 



16. A. rutcnfolia, Mart. ; st. 6-9 in. 1., firm, naked ; barren segm. short-stalked, 

 2-3 in. I., 1-1| in. br., oblong, hi- or tripinnatifid ; pinnte subdistant, lanceolate, 

 cut down nearly to the rachis into narrow toothed or sligiitly piunatifid divisions ; 

 texture subcoriaceous ; surfaces slightly hairy ; panicle subsessile, close, 1-1| in. 1. 

 —Mart. t. 55. A. glareosa, Gard. 3ISS. 



Hab. South Brazil, Martins, Gardner 5339. — This may be a variety of the next, from 

 which it seems to differ principally by its subsessile panicle. 



17. A. adiantifolia, Sw, ; rhizome creeping ; st. 12-18 in. I., firm, naked ; barren 

 segm. short-stalked, 6-9 in. 1., 4-6 in. br,, deltoid, bitripinnate ; pinnce close, 

 lanceolate, the lowest the largest ; ult. divisions oblong or linear-cuneate, the outer 

 edge toothed ; texture coriaceous ; rachises slightly pilose ; veins fine, channelled, 

 flabellate ; panicle 3-4 in. I., the peduncle 1-3 in. 1. — Plum. t. 158. 



Hab. Cuba, Bahamas, Florida, and Mexico to Bahia. — A. asplenifolia, Sw. (Hk. &G-r. 

 t. 16), is a reduced bipinnate form. This forms the genus Anemirhiza of J. Smith, cha- 

 racterized by an elongated rhizome, from which the stems arise in a single row. A. carui- 

 folia, Presl, is a finely-cut variety, 



18. A. cuneata, Kze. ; rhizome creeping ; st. 3-4 in, 1,, slender, naked ; barren 

 segm. long-stalked, 3-4 in. 1., tripinnatifid, with distant pinnse and pinnls., the 

 ult. divisions linear-cuneate, ^ lin, br,, cleft at the apex ; texture subcoriaceous ; 

 rachis and surfaces naked ; panicle slender, lax, the lower branches elongated, the 

 peduncles slender, I5 in. 1. — Kze. Anal. Pter. 8. t. 5. 



Hab. Cuba, Pceppig. — Perhaps a small finely-cut form of the preceding. 



§§ Anemidictyon, J", Sm. Paiiicle and leafy portion united in the same frond ; 

 veins anastomosing. Sp. 19-21. Fig. 65. e. 



19. A, (Anemid.) Tweediana, Hk, ; s^. 3-4 in. 1., naked or slightly pilose ; 

 barren segm. \\-2 in. 1., 1 in. br., ovate-oblong, simply pinnate; pinnce in 2-3 

 sessile pairs, oblong, | in. 1., f in. br,, the point blunt, the edge crenulate, the 

 base rounded ; texture subcoriaceous ; main vein not distinct to tlie apex ; panicle 

 1-2 in. 1., dense, the lower branches short, the peduncle 1-2 in. 1. — Ilk. Ic. t. 906. 



Hab. Uruguay and South Brazil, 



20. A. (Anemid.) Schraderiana, Mart. ; st. 6-9 in, 1., villose below ; barren 

 segm. 3-5 in. each way, witii 1-3 nearly equal pinnce on each side, which are 2-2^ 

 in. 1., 1 in. br., ovate-acuminate, the edge subentire, the base cuneate, the ter- 

 minal pinna with 2 divergent lanceolate lobes ; texture subcoriaceous ; main vein
