 in. 1., 2 in. br., ■with several distant horizontal lanceolate pinnm on each side, 

 which are only lobed in the upper third, but cut down below into spathulate 

 pinnl. 2 lin. 1., ^ in. br. ; teseture herbaceous ; rachis naked, flaccid ; veins 

 pinnate ; sori few, small, linear-oblong. — Hh. JSp. 3. p. 192. 2nd Cent. t. 27. 



Hab. Jamaica, McFadyen. — This is a feebler plant than th6 less cut forms of A . rMzo- 

 phyllum, with fewer and more distant pinnae and pinnules. 



162. A. tenuifolium, Don ; st. tufted, 3-6 in. 1., slender, naked, slightly 

 ebeneous ; fr. 6-12 in. 1., 3-6 in. br., oblong-lanceolate, with numerous pinnce 

 on each side, the lower ones 2-3 in. 1., f in..br. ; lower pinnl. siibdeltoid, cut 

 down to a narrowly-winged rachis into spathulate segm. ^ in. br., sharply 

 incised on the outer edge ; texture thinly herbaceous ; rachis green, naked, 

 slender ; veins solitary ; sori 1 or 2 to each segm. placed on the disk. — Hi. Sp. 3.

Hab. Himalayas, Neilgherries, Ceylon, Malayan Peninsula. 



163. A. rhizoph/llwm, Kunze ; St. tufted, 2-6 in. 1., greyish, naked ; fr. 6-12 

 in. 1., lJ-2 in. br., cut down into numerous close-placed horizontal pinnm on 

 each side, the central ones 1 in. 1., J-§ in. br., cut down throughout nearly to the 

 centre into simple or forked erecto-patent pinnl., the lowest on the under side 

 suppressed ; texture herbaceous ; rachis compressed, winged ; vdns one to each 

 segm. ; sori solitary, submarginal. — A, dubium. Brack, (3, A. myriophyllum, 

 Presl ; fr. broader ; central pinnm \\ in. 1., with lower pinnl, cut down into 

 several simple or forked linear segm. — Hk. Sp, 3. p. 200. 



Hab. Florida, Trop. America, Polynesia. — A. atrictvm, Brack, t. 23, differs from the 

 typical plant by its stronger rachis, and pinnules of the upper half of the pinnse linear- 

 falcate and simple ; A. Mfissum, F&, is a slender form, with pinnati&d pinnules with 

 distant linear segments; and A. cladolepton, P^e,'has cnneato-flabellate lower pinnules 

 deeply 2- to 3-cleft at the apex. A. dubium has a creeping rhizome, and is probably 

 distinct. 



154. A. nctaeeum, Mett. ; st. tufted, 1-4 in. 1., naked, polished, chesnut-brown ; 

 fr. 6-12 in. 1., 3-4 in. br., oblong-lanceolate, elongated and radicant at the apex ; 

 pinnm numerous, close-placed, horizontal, the central ones 1-1^ in. 1., J-^ in. br., 

 cut down to the rachis into numerous rhomboidal pinnl. 2 lines each way ; 

 lowest segm. spathulate, stalked ; textwe thinly herbaceous ; rachis polished 

 and chesnut-brown like the stem ; veins one to each segm. ; sori solitary, central. 

 T-Hh. 8p. 3. p. 203. 2nd Cent. F. t. 34. 



Hab. Venezuela, New Granada, Ecuador, Galapagos Island — This differs from the 

 preceding by its radicant habit and distinctly obovate-spathulate pinnules. It comes near 

 A. rachirhiam, Kaddi. 



165. A. cicutarium, Swartz; sJ. tufted, 4-8 in. 1., firm, greenish, naked ; /n 

 6-16 in. ]., 4-6 in, br., with 10-16 horizontal />«m»<8 on each side, the lower ones 

 2-3 in. 1., 1 in. br., cut down to the rachis into numerous ovate-rhomboidal 

 pinnl., which are |-| in. 1,, i in. br., obliquely truncate on the lower side, and cut 

 down to the rachis throughout into linear or oblong segm., the latter once or 

 twice cleft at the apex ; textwe ihm\y herbaceous ; colour bright-green ; rachis 

 compressed and often winged ; sori principally in two rows along the pinnl.— 

 Hk. Sp. 3, p. 198.— ft A. ah/ssinicim, Fee ; fr, flaccid ; texture thin ; pinnl. 

 and segm, fewer and broader. — Hk, Sp, 3. p. 191, 



Hab. Tropical America, from Cuba and Mexico to Peru ; Abyssinia, Macalisberg, Guinea 

 Coast, — A. mmtverdense, Hk. 2nd Cent, t, 41, appears to be a reduced form of this.
