 way from the margin, 2 inferior approaching the midrib, mostly double. — Metten. Fil. Lips, 

 t. \2.f 3. 4.- a leaf-segment, distinguished from our form by a serrulate margin. — Dipla- 

 zium, Kze. — " Stem 2' high, inclined to be arboresceut " {Pd.) ; segments 4"-5" long, 1" 

 broad.— Hab. Jamaica!, Macf, Pd.; Trinidad!, Pd. ; [Venezuela!, New Granada!;

 acuminate, rounded-subtruncate at the equal base, repand or crenate : veins dichotomous, 

 jertile at the anterior and posterior distant branches ; sori linear, extending to a small dis- 

 tance from the margin, anterior inferior approaching the midrib, double, superior simple, 

 distant from the midrib. — Metten. Asplen. t. 5.f. 3 : part of a segment. — Hemionitis, Sw. 

 Diplazium, Sw. — Proportions of the leaf as in the preceding, but "petiole from the root" 

 (Sw.).~- Hab. Jamaica!, Macf, Jl., Wils. ; Triuidad!, Woodford; [Cuba! to Brazil!]. 



TT Veins forked-dichotomous or pinnately divided, free, lowest all on the superior side of 

 their rib ; leaf pinnatisect. 



217. A. juglandifolium, Lam. (non Hook.). Leaf pinnatisect : segments oblong- 

 lanceolate or lanceolate-oblong, shortly acuminate, cuneate or rounded at the base, repand- 

 entire or serrulate above : veins dichotomous in the terminal, most 2-partite in the lateral 

 segments, fertile at the antenor inferior (rarely also at the posterior) branches ; sori linear, 

 intermediate between the midrib and margin, all or inferior approaching both, inferior of 

 the terminal segment double, those of the lateral segments simple. — SI. t. 37. Schk. Crypt. 

 I- 85. dextr. — From Hooker's homonym I exclude Sloane's figure : for its sori (all anterior 

 and double) do not extend to near the margin, and the penultimate lowest veins are at the 

 inferior side of their rib (Fendl. PL Venez. 498, Spruce, PI. Ecuad. 5337 : A.Fendlerianum, 

 Gr.).— Diplazium, Sw. A. Ecemerianum, Kze.— Stout ; segments 6"-8"(-4") long, 2"-

218. A. semihastatum, Kze. Leaf pinnatisect : segments lanceolate or ovate-lan- 

 ceolate, bluntish, upwards auricled 'at the cuneate base, serrulate or pinnatifid-pinnatipartite 

 below : veins forked above, superior simple, lowest pinnately divided, fertile at the anterior, 

 in the auricle also at the posterior branches ; sori linear, intermediate between the midrib 

 and margin, distant from both, inferior (or few) double.— Metten. Asplen. t. 4. / 17. 18 : 

 leaf-segments. Hook. Spec. t. 207.— A. cubense, Hook. I A. hymcnodcs, Metten. (I. c. t. 

 5 -/- 18. 19) : the form with broader, blunt, towards the base divided segments. Diplazium 

 angustifrons, Pr.—V-2' high ; segments l"(-2") long.— Hab. Jamaica (Sw.) ; [Cuba !]. 



219. A. auriculatum, Metten. {non Sw.). Leaf pinnatisect : segments lanceolate or 

 oblong-lanceolate, acuminate or bluntish, upward auricled at the obliquely cuneate base, 

 sinuate or slightly pinnatifid to one- fourth .- lobes dentate-serrulate.- veins dichotomous, 

 fertile at the lowest anterior, in the auricle also at the posterior branches ; sori linear, ap- 

 proaching the midrib at their base, distant from the margin, inferior (or few) double.— 

 Diplazium, Kaulf. A. arboreum, W. sec. Kaulf: but not arboreous Hook. ! (ex Wr. 

 Cub. 1034).— H'-2' high ; segments 2"-4" long, 8"'-12"' broad.— Hab. Jamaica!, all coll. ; 

 S. Vincent!, Guild.; [Cuba I to Brazil]. 



220. A Shepherd! Spreng. Leaf pinnatisect: segments oblong-lanceolate, acumi- 

 nate, inferior pinnatifid 'to the middle: lobes ovale, bluntish, appressed-serru/ale, gradually 

 decrescent and passing into serratures in the superior segments : temlets pinnate, mot) 

 forked above, anterior inferior or most fertile; sort linear, mf-rwr approaching the midrib 

 at their base, all distant from the margin, inferior in the superior segments (or few; double.
