151. A. Fadyeni, Hk. ; st. scattered, 3-4 in. 1., slender, scaly below ; //•. 6-8 

 in.-L, 2 in. br., with several distant horizontal lanceolate pimice on each side, 

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

 pinnl. 2 lin. 1,, | in. br. ; texture herbaceous ; rachis naked, flaccid ; veins 

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



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

 phyllum, with fewer and more distant pinnse and pinnules. 



152. A. temiifoliwn, Don ; st. tufted, 3-6 in. 1., slender, naked, slightly 

 ebeueous ; fr. 6-12 in. 1., 3-5 in. br., oblong-lanceolate, with numerous jnnnce 

 on each side, the lower ones 2-3 in. 1., f in. br. ; lower pinnl. subdeltoid, 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. — Hk, Sp. 3. 

 p. 193. 2nd Cent. F. t. 29. A. concinnum, Wall. 



Hab. Himalayas, Neilgherries, Ceylon, Malayan Peninsula. 



153. A. rhisopJiyllum, Kunze ; st. tufted, 2-6 in. 1., greyish, naked ; fr. 6-12 

 in. 1., 1^-2 in. br., cut down into numerous close-placed horizontal pinnce 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 p>innl., the lowest on the under side 

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

 segm. ; sori solitar}-, submarginal. — A. dubium. Brack. /3, A. myriophyllum., 

 Presl ; fr. broader ; central pinnoi \\ 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. strictum, 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, bifissum, Fee, is a slender form, with pinnatifid pinnules with 

 distant linear segments; and A. cladoJepton, Fee, has cuneato-fiabellate lower pinnules 

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

 distinct. 



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

 fr. 6-12 in. 1., 8-4 in. br., oblong-lanceolate, elongated and radicant at the apex ; 

 pinnce 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 ; texture thinly herbaceous ; rachis polished 

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

 —Hk. Sp. 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. rachirhizon, Raddi. 



155. A. cicutarium, Swartz ; s^. tufted, 4-8 in. 1., firm, greenish, naked ; /r. 

 6-15 in. 1., 4-6 in. br., with 10-15 horizonta.1 pinnce 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 f-| in. 1., J 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 ; texture thinly herbaceous ; colour bright-green ; rachis 

 compressed and often winged ; so7-i principally in two rows along the pinnl. — 

 Hk. Sp. 3. p. 198. — ^, A. abyssinicum, Fe'e ; fr. flaccid ; texture thin ; 2)innl. 

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



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

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