232 38. ASPLENIUM, DIPLAZIUM. 



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

 pinnae 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 ; rachis firm, erect, naked ; veins pinnated, pel- 

 lucid, about 5 at the edge to a group ; sort irregular, falling slightly short of 

 both midrib and edge. Hk. Sp. 3. p. 241. 



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

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

 this comes near A. oligophyllum. 



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 

 pinnce, the lower ones sessile or slightly stalked, 4-8 in. 1., 1^-2 in. br., the 

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

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

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

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

 p. 242. Fil. Ex. t. 242 (not Lam.). 



Hab. Cuba southward to Peru. A larger and usually more coriaceous plant than the 

 last, with a sub-arborescent caudex. A. Roemerianum, 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 pinnae on each side, the lowest 

 on stalks | in. 1., the pinna 6-8 in. 1., f-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. Aspl. 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 pinnae with a cordate base and toothed involucre. This has the texture of 

 A. celtidifolium, but the pinnse 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 1., 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, G-9 in. 1., l-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 firm, 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. Hk. Sp. 3. p. 240. 



Hab. Cuba and Columbia to Ecuador and Brazil. I), crenulans, F6e, from Guade- 

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

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

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



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

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

 with numerous spreading pinnce, the largest 3-4 in. 1., ^-f in. br., the point 

 acuminated, the edge broadly lobed to a depth of \-\ 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. Hk. Sp. 3. p. 248. (in part) Beddome, Fil.
