scaly below, ebeneous ; fr. 2-3 ft. 1., 9-12 in. br., the point pinnatifid, with 12-20 

 pinnce on each side, the lower ones 2 in. or more apart, distinctly stalked, 4-6 

 in. 1., 1-1^ in. br., the point acuminate, the edge slightly toothed, and sometimes 

 broadly lobed below, the base equally rounded on both sides ; texture thinly 

 herbaceous ; colour deep-green ; racAw' firm, erect, naked ; veins pinnated, pel- 

 lucidj about 5 at the edge to a group ; sori irregular, falling slightly short of 

 both midrib and edge.— M-. Sp. ^. p. 241. 



Hab. Cuba to Ecuador and Brazil, and we cannot distinguish a plant from the Ladvoneg 

 gathered by Capt. Carmichael. — The sori are sonaetimes scarcely at all double, and then 

 this comes near A. oligophyUum. 



214. A. (Dipl.) flavescens, Mett. ; st. 1 ft. or more 1., firm, erect, brownish, 

 nearly naked ; fr. 2-3 ft. 1., 9-18 in. br., with a large terminal and 10-15 lateral 

 pinna;, the lower ones sessile or slightly stalked, 4-8 in. 1., l|-2 in. br., the 

 point acuminate, the edge subentire or slightly toothed, the base narrowed or 

 rounded equally on both sides ; texture papyraceous or subcoriaceous ; colour^ 

 bright-green ; racMs firm, erect, naked ; veinlets dark-green, 3-4 in a group ; sori 

 falling slightly short of both edge and margin.— A. juglandifolium, Hk. Sp. 3. 

 p. 242. Fil. 'Ex. t. 242 {not Lam.). 



Hab. Cuba southward to Peru. — A larger and u.sually more coriaceous plant than the 

 last, with a sub-arborescent caudex. A. Boemerianum, Kze. {A. caucense, Karst,), is a 

 variety with laxer veins and pinnae slightly toothed. 



215. A. (Dipl.) rhoifolium, Mett. ; st. firm, erect, 1 ft. 1., naked ; fr. 2-3 ft. 1., 

 12-15 in. br., with a pinnatifid apex and 10-20 pinnce on each side, the lowest 

 on stalks | in. 1., the pinna G-8 in. I., |-1 in, br., the apex acuminate, the edge 

 subentire, the base on both sides rounded ; texture subcoriaceous ; rachis and 

 both sides naked ; veins 5-6 in a cluster, the sori reaching nearly to the edge ; 

 invol. narrow, thin. — Mett. Asj)!. p. 178. A. sambucifolium, Presl. 



Hab. New Granada. — A. Triance, Mett. Fil. N. G. p. 233, is said to differ from this by 

 its opposite pinnas with a cordate base and toothed involucre. This has the texture of 

 A . celtidifolium, but the pinnae are more numerous and narrower, with the fruit prolonged 

 almost to the edge. 



216. A. (Dipl.) celtidifolium, Kunze ; st. strong, erect, 1 ft. or more I., brownish, 

 paleaceous below •,fr. 2-4 ft. 1., 9-18 in. br., with a pinnatifid apex and numerous 

 pinnce on each side, the lower ones distinctly stalked, 6-9 in. ]., 1^-2 in. br., the 

 point acuminate, the edge subentire or slightly toothed, sometimes with short 

 blunt lobes ^ in, deep, the base rounded or cordate on both sides ; texture sub- 

 coriaceous ; rachis finii, often slightly fibrillose ; veins pinnated, the same colour 

 as the frond, 4-6 in a group ; sori beginning at the midrib, but falling short of 

 the edge.— -ffii-. Sp. 3. p. 240. 



Hab. Cuba and Columbia to Ecuador and Brazil. — D. crenulans, F^e, from Guade- 

 loupe, is probably a form. Our specimen has coriaceous pinnas bluntly lobed throughout 

 to a depth of \ in., and 8-10 veins in a group. The Javan and Philippine A. Lohhianum 

 (Hk. Sp. 3. p. 244 ; 2nd Cent. t. 17) agrees with this very nearly. 



217. A. (Dipl.) st/lvaticum, Presl ; caud. decumbent ; st. 1 ft. 1., firm, erect, 

 brownish, naked, scaly at the base ; //•. 1-2 ft. 1., 4-8 in. br., ovate-lanceolate, 

 with numerous spreading jmince, the largest 3-4 in. 1., ^-| in. br., the point 

 acuminated, the edge broadly lobed to a depth of ^-1 lin., and the base nar- 

 rowed suddenly on both sides ; texture thin, herbaceous ; rachis firm, erect, 

 naked ; veins fine, pinnated in the lobes, 5-7 to a group ; sori in long slender 

 lines reaching nearly to the edge. — Ilk. Sp. 3. p. 248. {in 2)art) Beddome, Fil,
